From the Latin Sacaveni, genitive of the personal name Sacavus: 'the [estate] of Sacavus'. A toponym characteristic of Roman Lusitanian fundi, preserved intact since imperial epigraphy.

Transparent compound: Vila Franca 'town with privileges' (charter granted by King Sancho I in 1212, freeing settlers from taxes) + Xira, a hydronym of disputed origin, probably pre-Roman over the Latinised form Cira.

From the Portuguese valada, derived from the Latin vallata 'palisaded, land enclosed by fence': a riverside hamlet that took its name from the defensive or agricultural enclosure that bounded it in medieval times.

A rare hybridisation between Roman Scalabis and the Christian dedication Sancta Irene —⁠the local 7th-century martyr⁠—⁠, fused in the Arabic pronunciation Shantarem; modern Portuguese Santarém preserves both strata in a single form.

Disputed toponym. The most widespread hypothesis derives it from the feminine of galego 'Galician': the town would have taken its name from a medieval female owner from Galicia. Other onomasts posit a pre-Roman hydronym without firm parallels.

From the Arabic az-zinâqa 'the narrow lane, the alley between walls': it designated the narrow passage between olive groves or fences typical of the Andalusian agricultural landscape. Birthplace of José Saramago, Nobel laureate in Literature.

From the Arabic aṭ-ṭalâʿiya 'the watchtower, the lookout post': it designated in al-Andalus the raised towers for watching borders or roads. Preserved intact in dozens of Iberian toponyms.

From the Arabic al-bayyâz 'the falconer' + nisba suffix -îr: 'the place of the falconer'. Falconry was an aristocratic occupation regulated in al-Andalus, attested in charters of privilege and hunting treatises.

From the Portuguese rabaça 'water-cress' (Apium nodiflorum) + collective suffix -al: 'cress-field, place where cresses abound'. The hamlet sits beside streams rich in this aquatic plant.

The Roman city —⁠not the modern one⁠— whose original name travelled sixteen kilometres north after the Suebic destruction of the 5th century, giving rise to today's Coímbra. Conímbriga today preserves only the ruins: the place that lost its name but keeps its form.

'Saint John of the Wood': parish dedication to John the Baptist + reference to the wooded mountain the town crossed. Madeira here retains the medieval sense of 'forest, wooded land', earlier than the modern sense of 'wood (material)'.

From late Latin Ecclesiola —⁠diminutive of ecclesia 'church'⁠—⁠, it evolved by aphesis and palatalisation to Igrijó and finally Grijó: 'the little church'. A common pattern in the rural toponymy of the Iberian northwest.

From the Latin Portus Cale —⁠'the port of Cale'⁠—⁠, a doublet between the pre-Roman settlement of Cale on the south bank of the Douro and the Roman port built on the north bank. The medieval contraction of the compound gave its name both to the city and to the kingdom of Portugal.

From the Latin personal name Barcalus + the suffix -os, marker of a Roman rural property ('the [estate] of Barcalus'). The famous legend of the Rooster of Barcelos —⁠a 15th-century Jacobean miracle⁠— is much later than the name and does not explain it.

Parish dedicated to Saint Victorinus (from the Latin Victorinus 'the victorious') + geographical qualifier dos Piães, probably derived from the Latin palumbarius 'dovecote' (via pião 'young pigeon'), alluding to the medieval presence of seigneurial dovecotes.

Transparent compound: ponte 'bridge' + the pre-Roman hydronym Lima, a river the Romans called Flumen Oblivionis —⁠'river of oblivion'⁠— because they feared crossing it would erase memory. Decimus Junius Brutus, in 137 BC, crossed it alone to prove the opposite.

From the Roman personal name Rubius/Rubilius + the plural locative suffix -ās: 'the [estate] of Rubius', with a plural marker of belonging to family members. The hamlet preserves that Roman epigraphic capsule in its name.

Galician diminutive of porro 'leek' (from the Latin porrum): 'the little leek-field', for the traditional crops of the Louro river meadows. Some onomasts reject the vegetal hypothesis and posit a medieval personal name Porrius; the popular association with the crop, however, is the most deeply rooted.

Etymology disputed between Latin arcata 'arcade, row of arches' —⁠in reference to the Roman bridge over the river Verdugo⁠— and an obscure pre-Roman origin. The modern form is attested from the 12th century.

From the Latin petronem —⁠'great stone, milestone'⁠—⁠, accusative augmentative of petra. The town grew around an ancient stone preserved beneath the altar of the church of Santiago, identified by the Jacobean tradition as 'the pedrón' to which the boat that brought the apostle's body was moored.

Compound of ponte 'bridge' + Cesures, a toponym of disputed origin: possible Latin caesura 'cutting, passage' —⁠referring to the meander of the Ulla that the bridge spans⁠—⁠, or an opaque pre-Roman root.

From the Castilian esclavitud 'condition of slave', an 18th-century Marian dedication: the Virgen de la Esclavitud —⁠'enslaved by love of humanity'⁠—⁠. The Baroque sanctuary that rose around a miracle gave its name to the hamlet that grew at its foot.

Toponym of disputed origin. Some onomasts connect it to the Indo-European root deiwos 'god' —⁠same family as gives tribal Tui⁠—⁠, reduced through Galician evolution; others posit an opaque medieval personal name. Attested since the 12th century.

Santiago from the Latin Sanctus Iacobus, 'Saint James'. Compostela has two readings: the scholarly one, from the Latin compositum 'cemetery' (from componere 'to bury'); the popular one, encouraged by the Jacobean legend, reads Campus Stellae 'field of the star', after the stars that in the 9th century revealed the apostle's tomb to Bishop Theodemir.

Transparent medieval French compound: 'Saint John at the foot of the pass', a hagiotoponym to John the Baptist + reference to the Pyrenean crossing the town guards. The coexisting Basque name, Donibane-Garazi, preserves the dedication and adds the regional name.

Pre-Roman toponym of disputed origin. The most widespread hypothesis derives it from the personal name Abilis or Abilus, attested in Celto-Gallaecian epigraphy, Latinised through Roman contact. Other onomasts posit a pre-Indo-European hydronymic root.

Probably from the Gothic personal name Wamba or Wimara, an early medieval owner whose name was fixed in the Latin genitive (villa) Wimaranis > Wuemanes > Güemes. Documented since the 10th century.

Disputed etymology. The dominant hypothesis proposes Late Latin cubiculum 'chamber, cabin, refuge' (the same root as Castilian cubículo and English cubicle). Other readings propose an opaque medieval personal name.

Pre-Roman hydronym of the river Navia, a possible derivative of the Celtic divinity Navia, goddess of waters attested in Hispano-Roman epigraphy of the Iberian northwest. The town inherits the name of the river at its mouth.

Transparent compound: vila (Galician, from the Latin villa) + alba (from the Latin alba, 'white', in reference to the lime of the walls or to the white coat of the cattle on its pastures). 'The white town.'

From the Gothic personal name Wadamundus or Badamundus, the early medieval owner of the estate, Latinised as the genitive (villa) Badamundi. Galician Romance voicing yielded Baamonde; the first element lost the intervocalic d-.

Transparent Galician compound: boi (from the Latin bos, bovem, 'ox') + morto (from the Latin mortuus, 'dead'). 'The dead ox', in reference to a commemorative founding episode whose precise detail is unknown.

From Andalusian Arabic Ishbiliya, the medieval Latinisation of the Roman name Hispalis — a pre-Roman word of disputed origin (possible Phoenician root spal, 'low, floodplain'), applied to the Turdetanian settlement on the Guadalquivir. After the 1248 Christian conquest, the spelling was Castilianised as Sevilla.

From the Latin Emerita Augusta = 'the emeriti of Augustus': a city founded in 25 BC by Emperor Augustus to settle the emeriti, the discharged veterans (emeritus = 'one who has completed service') of the V Alaudae and X Gemina legions.

From the Arabic Qazris (قَصْريش), an adaptation of the Latin Castris —⁠the ablative plural of castra, “camp”⁠—⁠, the colloquial name of the settlement beside the camp of Castra Caecilia (not the colony Norba Caesarina, an ephemeral foundation abandoned in the 4th century). Medieval Arabic preserved that Latin word and returned it to Castilian.

From pre-Roman Capera, an indigenous word of disputed origin (possible pre-Celtic root or a Lusitanian personal name), Latinised as the name of mansio XXIV of the Roman road. The city was abandoned in the 8th century, and only the famous tetrapylum over the road now remains.

Descriptive compound: baños (from the Latin balneum, 'thermal bath') + de Montemayor, in reference to the Sierra de Béjar closing the valley to the north (literally, 'of the greater mountain'). The Roman baths of Via XXIV named the village.

From pre-Roman Helmantica or Salmantica, a Vaccaean-Celtic word attested by Polybius in the 2nd century BC. Disputed etymology: possible hydronymic sal- root (referring to the river Tormes) + suffix -mantica of opaque meaning. The initial S- replaced the original aspirated H- after Latinisation.

Disputed etymology. The most widespread reading derives the toponym from the Arabic Šamûra (سمورة), adapted from the pre-Roman indigenous word Sentica or a Vaccaean derivative of the river Duero. The initial Z- preserves the Arabic sibilant š palatalised in medieval Castilian.

From Andalusian Arabic Sajra (صخرة) — 'rock, crag' —⁠, in reference to the stony hill on which the Muslim fortress settled in the 9th century. The initial Z- preserves the Arabic affricate s palatalised in medieval Castilian.

Diminutive of almendral (from the Arabic al-lawz, 'the almond', Latinised with the collective suffix -al): 'the small almond grove'. The almond-tree landscape documented in these lands from the 12th century justifies the descriptive toponym.

From Andalusian Arabic al-Kuwašgar, of disputed origin: a possible derivative of the Berber personal name Kuwašgar of an 8th-century local chieftain, or an Arabic adaptation of a pre-Roman word. The initial al- is the petrified Arabic article.

Transparent compound: aldea (from the Arabic aḍ-ḍaīʿa, 'the estate, the village') + nueva (Latin nova) + del Camino. A medieval Christian foundation on the Roman road, with the qualifier added to distinguish it from the nearby Aldeanueva del Cañedo.

Descriptive compound: fuente (Latin fontem) + roble (Latin robur, 'hardwood, sturdy oak') = 'spring of the oak'. De Salvatierra refers to the historical region (Salva Terra = 'protected land', a medieval charter).

Medieval compound: granja (from Old French grange, 'granary, monastic agricultural estate', through the Cistercian orders) + Moreruela, the medieval personal name of an early medieval owner (Maurusiana, a possible diminutive of the Byzantine personal name Maurus).

Compound: puebla (from the Latin populare, 'to settle', a medieval noun for 'new settlement with charter') + Sanabria, a natural region of disputed etymology (possible pre-Roman root sen- over the river Tera, or a derivative of Latin senabra).

From the Latin Aurientia or Auriense, derived from the Latin aurum ('gold'), after the gold-bearing outcrops of the river Miño that the Romans exploited from the 1st century. The Galician form Ourense preserves the diphthong au- > ou-; the Castilian Orense simplified it.

From Late Latin monasterium 'monastery', a learned word taken from the Greek monastḗrion ('place of one who lives alone', from monos 'alone'). It designates a primitive early medieval cenobium —⁠probably Mozarabic⁠— that disappeared around the 12th century. The suffix -erio preserves the learned Latin form.

From the Latin caccabus 'pot, clay vessel', with the augmentative suffix -oso: 'place of clay pots, pottery'. Documented since the 13th century in reference to the area's pottery activity, linked to the clays of the river Jerte.

Toponym of disputed origin. The dominant hypothesis proposes a pre-Roman root tab- of opaque meaning, attested in other peninsular toponyms (Tábara in Zamora, Tabarca in Alicante). Others derive it from the medieval personal name Tabari without firm parallels.

Disputed etymology. The most widespread hypothesis derives the toponym from Late Latin gutta ('drop') with the suffix -ina, in reference to the area's water sources; others propose a pre-Roman root gud-. The Galician article A (feminine) marks it as a proper noun.

From Andalusian Arabic Ḥilyāna (حليانة), an adaptation of the Latin personal name Iuliāna (feminine of Iulius, a Roman gens name). 'The one of Juliana' → a Roman, Hispano-Roman or Visigothic woman owner whose name became fixed to the rural estate.

Transparent compound: calzada (Latin calceata, 'paved', passive participle of calceare 'to shoe') + de Béjar, in reference to the regional head town. The village sits on the preserved stretch of Roman Via XXIV — the calzada you walk on is the toponym.

Transparent compound: castillo (from the Latin castellum, diminutive of castrum, 'small fortified camp') + blanco (from the Germanic blank, 'bright, luminous') + de los Arroyos, in reference to the streams crossing the municipal area. 'The white castle of the streams.'

Compound: real (from the Latin regalis, 'of the king' — royal camp or quarters) + de la Jara, in reference to the Mediterranean rockrose scrub (Cistus ladanifer, from the Greek kistos) that covers the range. 'The royal camp of the rockrose grove.'

From Late Latin casar ('group of houses, modest hamlet', substantivised plural of casa) + de Cáceres, in reference to the head town 12 km away. Casar without diminutive suffix preserves the direct medieval form from Latin, distinct from caserío or casería.

Compound: calzada (Latin calceata, 'paved', see Calzadilla and Calzada de Béjar) + Valdunciel, from the compound Val + dunciel = 'Valley of Dunciel', an early medieval personal name. The village sits on the exact course of Roman Via XXIV between Salamanca and Zamora.

Descriptive compound: cubo (from the Latin cupa 'barrel, wine container', also the root of cuba) + de la Tierra del Vino, a historic wine-growing region south of Zamora. The toponym commemorates the village's cooperage and winemaking tradition since the Middle Ages.

Disputed etymology. The most widespread hypothesis derives the toponym from the Latin lacia or laqueata ('interwoven, intertwined'), applied to the valley interwoven with streams. Others propose a pre-Roman root lakk- of hydronymic meaning.

Compound: xunqueira (from the Latin iuncaria, 'place of rushes', a derivative of iuncus + collective suffix -aria) + de Ambía, the floodplain region of the river Arnoia, in reference to the local marsh reed beds.

Toponym of disputed origin. The dominant hypothesis proposes a pre-Roman root ker- of opaque meaning, attested in other northwestern toponyms (Cea in León, Ceán in A Coruña). Others derive it from Late Latin cedere ('to yield, to grant') after some medieval jurisdictional privilege, without firm attestation.

Disputed etymology. The dominant hypothesis derives the name from the Gothic personal name Allini or Alini, an early medieval owner whose estate became fixed in the Latin genitive (villa) Allini. Others propose a pre-Roman root lal- without firm parallels.

From the Germanic banda ('strip, group distinctive, ensign'), through Old French bandiere and medieval Catalan bandera: 'ensign, standard'. The toponym probably commemorates a medieval jurisdictional episode —⁠seigneurial concession, coat of arms or privilege⁠— now lost.

Transparent compound: ponte (Latin pontem, 'bridge') + Ulla, the pre-Roman hydronym of the river the bridge crosses. Ulla has disputed etymology: possibly pre-Indo-European or Celtic with a hydronymic root ul-.

From the Latin personal name Lupianus (a derivative of Lupus, 'wolf', a frequent Roman personal name), Latinised as the medieval genitive (villa) Lupiani = 'estate of Lupianus'. Romance voicing -p- > -b- and vowel elision gave Lubián.

Hagiotoponym: Santa Marta (sister of Lazarus of Bethany, patron saint of innkeepers) + de Tera, the pre-Roman hydronym of the river that crosses the village. The saint's monastery, founded in the 7th century, originated the first documented pilgrim hospital on the Camino del Plata.

Transparent compound: Val de la Casa = 'valley of the house', a medieval Castilian agglutination of valle (from the Latin vallis) + casa (from the Latin casa). The toponym commemorates the early medieval rural possession of an isolated casa solar in the river Sangusín valley.

From Andalusian Arabic al-yusayn (الحسين), an affectionate diminutive of Hussein, a personal name linked to the Prophet's family. The initial al- is the petrified Arabic article, assimilated before the solar consonant y-.

Compound: aldea (from the Arabic aḍ-ḍaīʿa, 'estate, hamlet') + del Cano, in reference to the dedication or to the medieval personal name Cano (Latin canus, 'grey-haired, white'), probably the nickname of a knight of the Order of Santiago who repopulated the place.

From the Castilian cañaveral = caña (from the Latin canna, 'cane, reed') + collective suffix -veral (a variant of -al over caña + -ver): 'place of canes, large reed bed'. It describes the vegetation of the Tagus floodplain and its streams.

Disputed etymology. The main hypotheses derive it from the Gothic personal name Galisten or from the Latin personal name Calixtus (Pope Calixtus II, owner of the estate in the 12th century), Latinised as (villa) Calistei → Galisteo. The voicing C- > G- is characteristic of medieval Castilian.

Compound: hagiotoponym San Pedro (the apostle named Petrus in Latin, 'stone', a calque of Aramaic Kefa) + de Rozados, the substantivised plural of the medieval verb rozar ('to clear, to open arable land by burning scrub'). A toponym of medieval repopulation.

Substantivised plural ethnonym: Asturianos, from the Latin gentilic asturianus ('belonging to the Astures', the pre-Roman people of the northwestern peninsula). A pure repopulation toponym: the village name is the gentilic of those who founded it.

Descriptive compound: Mom- (contraction of Latin mons, 'mount') + -buey, from the Latin bos, bovis ('ox') in the collective formation bovetum ('herd of oxen'). Under the pastoral reading it means 'the mount of the oxen'. Some onomatologists alternatively propose a medieval personal name under the second element, but the documentation is ambiguous.

Possessive toponym of Latin origin: [Villa] Verini, '[the estate] of Verinus'. From the Latin anthroponym Verinus (derived from the adjective verus, 'true, sincere') in the genitive -ini. The name of the owner of a late-Roman rural villa was fixed as the place name after the dissolution of the villae network.

Possessive toponym of Germanic root: [Villa] Alarici, '[the estate] of Alaricus'. From the Gothic anthroponym Ala-reiks (a compound of ala-, 'all, complete', + reiks, 'powerful, ruler'), latinised in the genitive Alarici. It preserves the trace of the Germanic aristocracy that settled in Galicia after the Suevo-Visigothic migrations.

Toponym of disputed origin. The most widespread reading interprets it as a possessive genitive of the Latin or late-Latin anthroponym Ovetus / Ofetus: '[the villa] of Ovetus'. Other onomatologists defend a pre-Roman toponymic base ow-/owet- of opaque meaning. There is no epigraphic record to settle the debate.

Romance reduction of Latin Lucus Augusti, 'the sacred grove of Augustus'. A compound of lucus (Latin, 'consecrated grove, ritual clearing') + the genitive of the emperor Augustus. The Roman foundation of 13 BC sat on a preexisting Celtic sanctuary: the most widespread reading identifies its titular god with Lug, the pan-Celtic deity of light and crafts, whose name the Latin homophony leveraged.

Toponym of transparent Latin root: from the Latin gradus, 'step, rung, stepped ford'. Applied to a crossing of the river Cubia where stones arranged in steps allowed people to cross dry-shod, it gave its name to the settlement that grew on the bank. Same root as English grade, Spanish grada, and the modern terms academic degree or military rank.

Compound toponym: Pola (the Asturian form of puebla, from the Latin populare, 'to populate') designated a town founded by royal charter, a privilege granted between the 12th and 14th centuries to repopulate strategic regions. Allande, the second element, is pre-Roman and of opaque meaning: the most widely accepted reading points to a hydronymic or topographic base, with no firm parallels.

Transparent descriptive toponym: from the Latin Fons Sacrata, 'consecrated spring'. A compound of the noun fons, fontis ('spring, fountain') + the participle sacratus ('consecrated, dedicated to a cult'). The Galician article A that opens the name is the feminine determiner: 'the sacred spring'. It documents a venerated spring at least since the Early Middle Ages — likely the Christianisation of an older pre-Roman sacred source.

Substantivised plural of Latin sala, a word of Germanic origin —⁠from Gothic or Frankish sal- 'manorial house, noble residence'⁠— that late Latin adopted to designate the main hall of a villa or palace. The toponym commemorates a group of seigneurial residences documented in the area since the Early Middle Ages.

Toponym of disputed pre-Roman origin. The attested medieval form is Tineiu (12th century), generally attributed to a Celtic or pre-Latin toponymic base of opaque meaning. Some onomatologists defend the Latin anthroponym Tinneus / Tineius; others, a pre-Roman hydronym. With no epigraphic record, neither reading has prevailed.

Toponym derived from late Latin virductum (popular variant of viridarium, 'green place, garden'), formed on the adjective viridis ('green, fresh, lush') plus the collective suffix -etum indicating abundance. It means, literally, 'place of green pastures' or 'land covered with greenery' — an exact description of the high-altitude meadow on which the village sits, just before the Palo pass.

Compound toponym in two layers. Grandas is the substantivised plural of Asturian granda, 'high, flat, stony land covered with low scrub, suitable for grazing but not cultivation', a pre-Roman word attested across the Cantabrian range. Salime, the second element, is a pre-Roman hydronym of opaque meaning that names the river Navia on this stretch and, today, the reservoir.

Substantivised Galician appellative: cádavo designates the burnt trunk of a tree that remains standing after a forest fire, covered in charcoal but still rooted. The most accepted etymon traces it to a pre-Roman base cad- related to the idea of burning or blackening; an alternative reading derives it from late Latin captivum ('captive, held back'), with less phonetic support. The toponym commemorates a place burnt at some point in the Middle Ages — the forest scar became fixed as the name of the place.

Descriptive compound from late Latin Castrum Viride, 'the green castro'. Castrum (Latin, 'fortified camp') came, in Galicia and Asturias by semantic specialisation, to designate the fortified hill settlements of the pre-Roman castreño culture — the Celtic castros that dot the peninsular northwest. Viride is the adjective viridis ('green, lush') in neuter agreement. The toponym commemorates an indigenous castro already overgrown with vegetation when medieval resettlers fixed the name.

Toponym of disputed origin. The most sustained reading derives the name from late Latin ferrolium, a diminutive of ferrum ('iron'), referring to the metalworking activity documented in the region since Roman times — ferric mineral extracted from the slopes that surround the estuary. Other onomatologists prefer an opaque pre-Roman base. The form Ferrol is attested from the 12th century.

Toponym of disputed origin between two strong hypotheses. The Latin one derives from late Latin Caronium or Crunia, possibly linked to an opaque pre-Roman base Latinised. The popular legend —⁠already in the 13th century⁠— connected it with the columna that supported the Tower of Hercules, the 2nd-century Roman lighthouse that still presides over the city. The Galician form A Coruña is attested from the 12th century.

Transparent compound toponym: Ponte (Galician 'bridge', from the Latin pons, pontis) + de Eume, the hydronym of the river that crosses the town. Eume is pre-Roman, of Indo-European root probably linked to the notion of 'water, flow', with parallels in European hydronyms such as the French Aume. The toponym commemorates the medieval bridge built by the Andrade family in the 14th century — one of the largest in Galicia.

Toponym of disputed origin. The most solid reading derives it from the Latin genitive plural Brittancium or Bettantiorum, 'of the Brittancii / Bettancii': a Hispano-Roman or late-Roman family (gens) documented in local epigraphy. Others propose a pre-Roman root of opaque meaning. The medieval form Bétanços appears from the 12th century in the records of the monastery of Sobrado.

Compound toponym. Hospital, from the Latin hospitale ('place of lodging'), specifically designates a medieval Jacobean hospice: a building founded to shelter pilgrims, with bed, food and basic care. Bruma, the second element, is pre-Roman and of opaque meaning — probably a Celtic base linked to a topographic or hydronymic feature, prior to the hospice that gives the place its current name.

Toponym of disputed origin between two readings. The Latin one derives from the occupational adjective secalarius ('rye grower or producer', from the Latin secale, 'rye'), with the Galician suffix -eiro designating the practitioner of a trade. The Germanic one proposes a Gothic anthroponym Sigerius / Sigeric, 'powerful through victory', in possessive genitive. Both are phonetically plausible; neither is firmly documented.

Pre-Roman toponym of opaque meaning. The most sustained hypotheses derive it from a hydronymic base prior to Romanisation, probably linked to the notion of 'watercourse, wet moorland', attested in toponyms of the Atlantic northwest. The medieval form Nesa appears in the records of the San Martiño monastery in the 11th century.

Substantivised plural of Galician-Portuguese cabana, 'hut, humble rural shelter', from late Latin capanna — a word of probable pre-Roman (Hispanic or Celtic) origin that Latin adopted to designate the rustic dwelling of shepherds and farm workers. The toponym commemorates a group of huts or shelters documented in the area since the Early Middle Ages: the cabanas that gave the place its name.

Toponym of disputed origin. The classical reading derives it from the Latin or late-Latin anthroponym Minius in possessive genitive, '[the villa] of Minius', a habitual pattern in Hispano-Roman toponymy. Other onomatologists connect it with the pre-Roman hydronym Mino that gives its name to the peninsular Miño river, here applied to the river Lambre that crosses the concello. Without epigraphic testimony or early documentation to settle the debate.

Transparent compound toponym: A Rúa (Galician 'the street, the paved way', from the Latin ruga 'wrinkle, furrow, paved road') + de Francos, gentilic in substantivised plural from franco, 'inhabitant of the Frankish kingdom' or, by medieval extension, any European of trans-Pyrenean origin. It documents a medieval settlement of Frankish merchants and artisans along the Camino, the same historical pattern that gave its name to the Camino Francés.

Substantivised Galician appellative: calle, from the Latin callis, 'narrow path, footpath, livestock passage'. In its original Latin sense and in conserved rural Galician, calle did not designate the urban street but the path itself —⁠the way worn by the constant passage of people and animals. The toponym preserves that primitive meaning: the place is called, literally, 'the path'.

Germanic loanword into late Latin: from Gothic baurgs or Frankish burg, 'fortified town, defended enclosure', Latinised as burgus and adopted by all Romance languages with semantic shift to 'suburb, fortified suburb of a larger city'. The toponym commemorates the medieval suburb raised outside the walls of A Coruña, over the Roman-medieval bridge of the river Mero.

Pre-Roman toponym of disputed origin. The attested medieval form is Calamir (11th century), generally read as a pre-Roman hydronym or oronym —⁠probably Celtic⁠— from a base kal- linked to the notion of 'stone, stony riverbank, watercourse over stone'. Some onomatologists defend a different base linked to a natural formation in an arc or bend. Without epigraphic testimony to settle the debate.

Toponym derived from the Galician-Portuguese carral, 'narrow path suitable for carts, narrow valley with cart passage', from the Latin carrus + the augmentative suffix -al of belonging/abundance. It specifically designates a topographic passage —⁠usually a tight valley or a path between ridges⁠— transited by ox-drawn carts in the medieval rural network. The toponym is frequent in Galicia and preserves the exact trace of an agrarian trade.

Compound toponym in three layers. Villafranca, 'free town, exempt from taxes', designated in the medieval repopulation a foundation with carta-puebla and its own charter — the adjective franco here is not a gentilic but a fiscal one. Montes de Oca, the orographic complement, locates the place in the eponymous range, whose name derives from the local river Oca, a pre-Roman hydronym of opaque meaning.

Compound toponym. Terradillos is the substantivised plural of the diminutive terradillo, from the Latin terra ('land') + the suffix -aculum/-uelo of diminutive, designating small plots of cultivable land. De los Templarios, the second element, commemorates the village's ownership by the Order of the Temple from the 12th century until its dissolution in 1312, during the repopulation of Tierra de Campos.

Descriptive compound toponym. El Burgo documents a fortified medieval suburb, from late Latin burgus —⁠a Germanic loanword⁠— which in Castilian designated a small town with its own charter. Ranero is a derivative of rana ('frog') with the suffix -ero of abundance, 'place abundant in frogs', describing the seasonal ponds of the León plateau where amphibians historically proliferated.

Compound toponym. Vega, from Hispanic pre-Roman baika / bega ('fertile river plain, low cultivable bank'), counts among the few pre-Roman terms that Castilian adopted as a common word with its meaning intact. De Valcarce particularises the place through the name of the valley: Val (Latin vallis, 'valley') + Carce, probably from the Latin carcer ('prison, confinement'), alluding to the narrow, hemmed-in valley that the river crosses.

Basque toponym of opaque origin. The most sustained reading derives it from untoa / unto, an archaic Basque word linked to the idea of 'valley floor, humid meadow' or 'depression', frequent in toponyms of the Navarro-Occitan Pyrenees. Without epigraphic testimony to settle the debate.

Basque-Pyrenean toponym of disputed origin. The most sustained readings connect it with archaic Basque bases related to water —⁠or-, present in hydronyms such as Oria or Orisson⁠— or with a Latinised pre-Roman anthroponym. Without early documentation or firm parallels to decide between them.

Two names superimposed. In Basque Auritz, 'place abundant in ferns or rockroses', from the Basque aur + the suffix -itz of abundance. In Castilian Burguete, a diminutive of the Germanic burgo ('small town with charter'), from late Latin burgus. The dual naming documents the historical bilingualism of the Erro valley.

Parallel dual name. In Basque Aurizberri, 'new Auritz', from the Basque berri ('new') — a medieval foundation as an annex of neighbouring Auritz/Burguete. In Castilian Espinal, from the Latin spinetum ('place of thorns'), with the collective suffix of abundance. The two names do not translate each other: each language gave its own label to the same landscape.

Descriptive Basque toponym: bizkar ('back, ridge, mountain crest') + the locative suffix -eta ('place of'). It means literally 'the ridge, the back' — an exact description of the elongated hill on which the village sits, on the watershed between the valleys of Erro and Aezkoa.

Basque toponym of disputed origin. The most widespread reading interprets it as a compound of a medieval anthroponym —⁠probably the Latinised Germanic Liñus / Lintius⁠— with the Basque suffix -ain, a locative of belonging: 'that of Liñus, the estate of Lintius'. Others connect it with opaque pre-Roman bases.

Descriptive Basque toponym: aker ('he-goat, billy goat') + the locative suffix -eta ('place of'). It means 'the place of the he-goats' — an exact designation of an area of goat-grazing documented since the Middle Ages in the Esteríbar valley, with characteristic scrubland slopes suitable for caprine livestock.

Descriptive Basque toponym: zarika ('willow', a word of old Basque) + the locative suffix -egi ('place of'). It means 'willow grove, place of willows', an exact description of the bank of the river Robo where the village sits, on the southern slope of the Sierra del Perdón.

Pre-Roman toponym of opaque origin. Contemporary Navarrese onomastics classifies it as Basque-Aquitanian of lost meaning, with parallels in Pyrenean toponyms of the same belt. Documented as Obanos from the 12th century, without earlier forms that allow the original base to be reconstructed.

Toponym of disputed origin. The most sustained readings derive it from a medieval anthroponym Mañer or Magnerius (Latinisation of the Germanic name Magnher, 'great in honour'), in possessive, following the pattern villa Magnerii → Mañeru. Another reading appeals to an opaque pre-Roman base.

Descriptive toponym: Villa Tuerta, from the Latin villa ('rural estate') + tuerta ('twisted, bent'), from the participle torta of torquere, 'to twist'. It describes the layout of the village, set in a meander of the river Iranzu — the hamlet curves following the line of the water, instead of the habitual straight layout of medieval villages.

Coordinated dual toponym. Ayegui, Basque, derives from ai ('slope, hillside') + the locative suffix -egi: 'place of the slope'. Irache, also Basque, comes from ira ('fern') + the suffix -tza/-tze of abundance: 'fern grove'. Today it designates the Irache monastery complex, famous among pilgrims for its 20th-century wine fountain.

Substantivised descriptive appellative: from the Latin ventosa, a feminine adjective agreeing with an elided villa — 'the windy (villa), exposed to the wind'. The toponym commemorates the precise geography of the place, on a hillock of the Najerilla valley through which the wind of the Sierra de la Demanda blows constantly.

Possessive toponym: from the Latin (villa) Ciriana, 'the villa of Cirius / Ciriacus', from the Latin anthroponym Cirius or Ciriacus in adjectival form. It follows the -anus / -ana pattern of Hispano-Roman possessive toponyms, where the adjective derived from the owner's name agrees with an elided villa.

Toponym derived from the Latin granio / granione ('place of grain, granary'), from granum ('cereal grain') with the augmentative suffix -onem. It designates an agricultural settlement characterised by its cereal production, a function documented since the Early Middle Ages in the Tirón valley.

Compound toponym. Redecilla is a diminutive of Latin retis ('net'), alluding to a system of branched canals or watercourses that irrigated the meadow — 'small net of waters'. Del Camino is a Jacobean complement added in the Middle Ages to distinguish it from other Redecillas, fixing its belonging to the Camino de Santiago.

Compound toponym: Castil, an apocopation of castillo (from the Latin castellum, 'small fortress') + Delgado, a medieval anthroponym or surname of the lord owner. The formula Castil + surname is a habitual pattern of Castilian toponymy for identifying seigneurial possession.

Dual toponym. Viloria, from the Latin villa aurea ('golden villa') or vill-oria (affective diminutive of villa, 'little villa'), depending on whether the semantic or morphological reading is preferred. De Rioja is a modern geographical complement (20th century) to distinguish it from other Vilorias. It is the documented birthplace of Saint Dominic of the Calzada.

Compound toponym: Villa Mayor, from the Latin villa maior ('greater estate, principal villa'), following the medieval comparative pattern to distinguish settlements by relative size. Del Río is a geographical complement that fixes the place on the bank of the Reláchigo river, a tributary of the Tirón.

Medieval contraction of Todos Santos, a hagiotoponym dedicated to the Christian feast of All Saints (1 November). The phonetic change follows the habitual pattern of Castilian agglutinations with loss of the unstressed middle syllable: todos sanctos → tosanctos → tosantos.

Toponym of disputed origin. The two competing readings are a Latin compound —⁠villa + ambistia, 'villa of double ford' or 'villa between two waters', with the Basque root ibi ('ford, river crossing') in the second element⁠— and an anthroponymic one that posits a medieval personal name Ambestia without firm documentation. Without epigraphic testimonies.

Compound toponym: Espinosa, an adjective derived from the Latin spinosus, -a ('full of thorns'), from spina, 'thorn', in feminine agreeing with an elided villa. Del Camino is a medieval complement that distinguishes it from other Castilian Espinosas and fixes it in the Jacobean network.

Toponym of disputed origin. The most sustained readings connect it with the Basque base aitz ('rock, crag, cliff') in its variant ag-, frequent in toponyms of the southern foothill of the Cantabrian range. Without early documentation or epigraphy that allows the base to be reconstructed with certainty.

Compound toponym. The most widespread reading derives Rabé from Hispanic Arabic rabad ('suburb, neighbourhood outside the walls'), a term that medieval Castilian adopted as a loanword and that in toponymy was applied to settlements that sprang up at the edge of a roadway or of a larger settlement. De las Calzadas documents the crossing of two Roman roads that converged here.

Hagiotoponym derived from the name San Antón Abbot (Anthony of the Desert, c. 251–356), father of Christian monasticism. The toponym commemorates the convent-hospital of the Order of Saint Anthony founded in the 12th century beside the Camino to attend to pilgrims suffering from 'Saint Anthony's fire', the ailment that gave the order its name.

Compound toponym. Población, from the Latin populatio ('the act of populating, human settlement'), designated in medieval Castilian a foundation built from scratch to repopulate recently reconquered land. De Campos places the village in the Tierra de Campos, the great cereal plain between Palencia, Valladolid, Zamora and León.

Compound toponym in three elements. Villa, from the Latin villa ('estate, rural settlement'). Alcázar, from Hispanic Arabic al-qasr ('the castle, the fortress'), a medieval Arabism. De Sirga, from the Latin syrica or from the Galician-Portuguese sirga, 'tow rope', alluding to the old technique of hauling boats up a river with ropes from the bank.

Toponym of disputed origin. The most widespread reading derives it from the Latin genitive plural Letigorum ('[of the] Letigii'), a Hispano-Roman gens documented in local epigraphy. Another reading, today minority, appeals to an opaque pre-Roman base related to minor watercourses of the Carrión basin.

Toponym derived from the medieval adjective moratino, a diminutive of moro (from the Latin maurus, 'inhabitant of Roman Mauretania'), used in medieval Castilian to designate the Andalusi Muslims. The substantivised plural 'Moratinos' would commemorate a small settlement of Mudejar or Morisco population documented in the Christian repopulation of Tierra de Campos.

Hagiotoponym dedicated to Saint Nicholas of Bari (4th century), patron of pilgrims, sailors and children. The complement del Real Camino documents the Jacobean condition of the village and its belonging to the Camino Real, a medieval administrative designation of the pilgrim ways protected by the Castilian crown.

Compound toponym. Calzada, from late Latin via calciata ('trodden road, paved way'), from the verb calcare, 'to tread'.

Hagiotoponym dedicated to Saint Martin of Tours (4th century), one of the most popular saints of medieval Europe, patron of soldiers, the poor and pilgrims. The complement del Camino distinguishes it from the dozens of peninsular San Martins and fixes its belonging to the Jacobean network.

Compound toponym. Villar, from the Latin villare (neuter diminutive of villa), 'small villa, lesser farmstead'. De Mazarife, from the medieval Arabic anthroponym Maṣārif (plural of maṣrif, 'irrigation canal, ditch') or, alternatively, from the Arabic personal name Maṣrūf.

De los Polvazares, derived from the Latin pulvis ('dust') with augmentative suffix, alludes to the dusty quality of the clay soil of the Maragatería plateau.

Toponym of disputed origin. The competing readings are an anthroponymic one —⁠from the medieval personal name Manjar or Manjarino, a hypocoristic of an unidentified Germanic anthroponym⁠— and a toponymic one that appeals to a pre-Roman base man- linked to orographic features. The hamlet sits at 1450 metres, at the top of the Foncebadón pass —⁠the highest point of the Camino Francés.

Possessive toponym of Germanic root. The most sustained reading derives the name from the Gothic anthroponym Rudilanus or Rudilani, 'the brave one in land', with the base hrod ('fame') + land ('land, dominion'), in Latinised genitive. It documents an early-medieval rural villa owned by a Visigothic lord of the Bierzo area.

Toponym derived from the Galician-Portuguese liñar ('flax field'), from the Latin linum ('flax', textile plant) with the suffix -ar of cultivated field.

Toponym derived from the Galician-Portuguese mercadoiro, from late Latin mercatorium ('place where one trades'), from mercatus ('market') with the locative suffix -orium. It documents an old market or rural fair point —⁠a frequent medieval institution on the Jacobean roads, where the flow of pilgrims justified periodic exchanges.

Descriptive compound toponym from the Latin castrum maior ('the greater castro, the big castro'), a comparative applied to one of the most extensive Celtic castros in the Galician pre-Roman network —⁠distinguished thus by its size in relation to other nearby minor castros. The archaeological site documents occupation from the 4th century BC until the 1st century AD.

Toponym derived from the Galician-Portuguese eirexa / igrexa ('church'), from the Latin ecclesia, in turn from the Greek ἐκκλησία ('assembly, congregation'). The substantivised toponym documents a hamlet formed around a medieval rural church, with no further descriptive complement —⁠the temple was the centre and the name of the place.

Hagiotoponym dedicated to San Xulián, the Galician dedication of Saint Julian the Hospitaller, patron of pilgrims and innkeepers in the medieval European tradition.

Toponym derived from the Latin castaneta ('chestnut grove, place abundant in chestnut trees'), from castanea ('chestnut tree') with the collective suffix -eta / -etum.

Compound toponym. Riba, from the Latin ripa ('bank, riverside'), designates the margin of a river. Diso is a contraction of de Iso, from the name of the Iso river —⁠a pre-Roman hydronym of opaque meaning that crosses the area. It documents a medieval settlement on the bank of the river Iso, where a Jacobean bridge crossed it.

Compound toponym. Condeixa is of disputed origin: the most widespread reading derives it from late Latin condicia ('condition, pact, seigneurial agreement'), alluding to the medieval repopulation pact with which the place was founded. A-Nova distinguishes this late-medieval foundation from the nearby Condeixa-a-Velha, settled on the Roman ruins of Conímbriga.

Compound toponym in two layers. Vila Nova, 'new town', designates a medieval foundation with a charter of privileges. De Gaia documents the old pre-Roman and medieval settlement that preceded the new town: Cale or Gaia, a hydronymic or anthroponymic root of disputed origin —⁠the same that named Porto (from Portus Cale) and the country Portugal.

Affective diminutive of Portuguese vilar ('lesser farmstead, rural hamlet'), from the Latin villare, with the suffix -inho. It literally means 'little villa, small farmstead'.

Substantivised plural of Latin arcus ('arch'), a common appellative applied both to architectural structures (bridge arch, triumphal arch, arcades) and to natural features with curved form (river bend, arched cliff). The plural form fixes the collective character.

Pre-Roman toponym of disputed origin. Contemporary Portuguese onomastics classifies it as hydronymic, with the base tam- present in other watercourse names of the European Atlantic quadrant (cf. the Galician river Támega, the Portuguese Tâmega, the British Thames). The precise meaning has been lost —⁠a word older than documented Celtic.

Toponym derived from the Latin arcucellum, a diminutive of arcus ('arch'), with the affective suffix -cellum that generated the Portuguese form -zelo. It means 'small arch', 'modest arches' —⁠a description applied either to minor architectural structures (a chapel arch, a small bridge arch) or to a curved geographical bend.

Toponym of disputed origin. The two competing readings are a Latin-Germanic one —⁠composed of the Gothic anthroponym Saxa ('Saxon') + munda ('protector, guardian'), a medieval personal name attested in Leonese charters⁠— and a toponymic one that appeals to Latin saxum ('rock') + mons ('mount'). Without firm documentation to decide between them.

Hagiotoponym dedicated to San Amaro, the Galician and Portuguese dedication of Saint Maurus the Abbot (6th century), disciple of Saint Benedict and patron of pilgrims in the popular tradition of the Camino. His devotion spread in the Middle Ages through the northwestern peninsular quadrant and gave its name to dozens of hamlets with their own hospice or hermitage.

Descriptive Basque toponym: hondar ('sand, sandbank') + ibi(a) ('ford, river crossing'). It means 'ford of the sandbank' —⁠an exact description of the historical crossing over the Bidasoa estuary, where the border with France was forded over the sandy bar of the mouth. The Castilianisation Fuenterrabía is a folk etymology unrelated to the original.

Basque toponym of disputed origin. The most sustained reading connects it with the hydronymic base or- ('water', present in hydronyms such as the river Oria, at whose mouth the town sits), of pre-Roman root linked to the liquid element.

Toponym of disputed origin. The most sustained reading derives it from the Latin or late-Latin anthroponym Cerdicus (a Hispanicised variant of the Germanic name Ceretik or of Latin Cerdicius), in possessive. Another reading appeals to a pre-Roman base cer- linked to relief, without firm parallels.

Toponym derived from the Latin insula ('island') with the plural locative suffix -ares, 'place of islets'. It describes the coastal geographical feature of the place: a series of rocky islets close to the beach that the low tide uncovers and the high tide covers. The plural marks the set.

Toponym of disputed origin. The two competing readings are a hydronymic one —⁠from a pre-Roman base liend- linked to watercourses, with parallels in Cantabrian and Basque toponyms⁠— and a toponymic one that appeals to Latin limitem ('limit, frontier'), applied to the valley that bordered the Laredo jurisdiction. Without firm early documentation.

Possessive toponym from the Latin Gallicianus, an adjective formed on the gentilic Gallaecus ('Galician') with the suffix -anus.

It designates a stony terrain —⁠a beach of rounded pebbles, rocky soil, stone hill⁠— on the edge of the Santander bay.

Compound toponym. Boo is of disputed origin —⁠Cantabrian onomastics connects it with an opaque pre-Roman base or with Latin bovis ('ox, bovine'), applied to a pastoral place. De Piélagos, from the Latin pelagus ('open sea, deep water', a Hellenism), describes the wide estuary of the Pas-Pisueña on whose bank it sits.

Pre-Roman toponym of disputed origin. Contemporary Cantabrian onomastics classifies it as hydronymic, with a base mog-/mogr- present in other northern peninsular toponyms linked to watercourses or coastal features. Without early documentation or firm parallels that allow the original meaning to be recovered.

Substantivised plural of Latin cupricia ('copper mines, copper places'), from cuprum ('copper'), a metal whose Latin name comes in turn from the island of Cyprus (Cyprus), the principal exporter in antiquity.

Toponym of disputed origin. The most widespread reading derives it from the Latin genitive plural Columbrorum ('[place] of the Columbri'), a Hispano-Roman or late-Latin gens documented in Cantabrian epigraphy. An alternative reading appeals to a pre-Roman base col- linked to relief, without firm documentation.

Toponym of disputed origin. The most sustained reading derives it from the Latin or late-Latin anthroponym Pendolius or Pendulius, derived from pendulus ('hanging, suspended'), in possessive plural.

Toponym of disputed origin. The most sustained reading derives it from the Latin expositum ('exposed', participle of exponere) applied to the open character of the coast or the Cávado estuary mouth. Other readings propose an unidentified medieval anthroponym or an opaque pre-Roman base.

Toponym of disputed origin. The most sustained reading derives it from the Latin faginum ('beech grove, place of beeches'), from the phytonym fagus (beech). Another reading proposes an unidentified medieval anthroponym in possessive. Portuguese phonetics of the final nasalisation fits the Latin derivation.

Compound toponym. Viana, a hydronym of pre-Roman origin (probably from the Celtic base vianna-, 'watercourse, river'), preserved as the name of the river Lima on its lower stretch. Do Castelo identifies the medieval castle of Santiago da Barra (16th century), which the Portuguese royal succession added to the toponym in 1848 to distinguish it from other peninsular Vianas.

Compound toponym. Vila + Praia ('beach town') + de Âncora, from the Latin ancora (in turn from the Greek ánkyra, 'anchor'). The name of the river Âncora originates, according to Portuguese onomastics, in a medieval legend about the anchor of a sunken ship; alternative readings propose a pre-Roman hydronymic base.

Portuguese affective diminutive: caminha, from the Portuguese caminho (Latin caminus, 'road, way') with the suffix -inha. It literally means 'little road, small passage' —⁠a description of the narrow historical passage that the road followed between the range and the Miño river before crossing into Galicia.

Substantivised Galician-Portuguese appellative: guarda, from the Germanic warda ('watch, protection, guard post'), a Gothic loanword into late Latin that passed to all the Romance languages. It documents a medieval fortress of vigilance over the mouth of the Miño —⁠the natural border between the Christian kingdoms of the northwest and medieval Portugal.

Toponym of disputed origin. The two competing readings are a hagiographic one —⁠from the name of the Cistercian monastery of Santa María de Oia (12th century), taken from an unidentified medieval anthroponym⁠— and a pre-Roman one that appeals to a base oi-/ou- of relief or watercourse, attested in other toponyms of the Galician coast.

Possessive toponym of Germanic root. The most sustained reading derives it from the Gothic anthroponym Mauricius (Hispanicised variant of Maurus, 'Moor, dark-skinned', with the suffix -itius), in Latinised plural genitive. It documents an early-medieval rural villa owned by a Hispanicised Germanic family lineage.

Toponym of disputed origin. The most widespread reading derives it from the Latin Baionnia or from a Celtic pre-Roman base bai- linked to the liquid element —⁠the same root that names French Bayonne, on the other Atlantic coast. The protected cove of Baiona was a documented Roman port (Erizana) and, in 1493, the first European port to receive news of the New World.

Possessive toponym: from the Latin (villa) Nigrini, 'the villa of Nigrinus', an anthroponym derived from the adjective niger ('black, dark') with the affective suffix -inus. It documents an early-medieval rural villa owned by a Nigrinus —⁠a popular Roman cognomen⁠— Hispanicised after the Christian conquest of Galicia.

Toponym derived from the Latin vicus ('hamlet, small rural settlement, street'), a basic geographical appellative of the Roman lexicon that specifically designated a settlement smaller than the oppidum (fortified city) and the municipium (city of Roman law). It is one of the most transparent Roman toponyms in the peninsular northwestern quadrant.

Romance syncope of the Latin phrase Summum Portum ('the highest pass'), applied by Roman itineraries to distinguish this Pyrenean col —⁠1,640 metres, passable by cart⁠— from the lesser passes of neighbouring valleys. The name is documented as Summo Portu in the 9th century and evolves by agglutination into Sompuerto, Sompuert and finally Somport, preserving both elements fused into a single word.

Agglutinated Latin phrase Campum Francorum ('field of the Franks'), medieval designation of the plain that opened immediately south of the Somport pass and served as a truce and trade zone between Franks and Aragonese. The agglutination of the two elements into a single word dates from the 12th century; earlier it is documented separately as Campo de Francos and Campo Franco.

Transparent Romance compound Villa Nova ('new town'), with the Aragonese phonetic peculiarity of preserving the unstressed final -a and stressing the penultimate syllable as acute —⁠Villa-nóva > Villanúa⁠—⁠. It designated the late medieval foundation of the present nucleus, an 11th-century repopulation over a small previous settlement of the valley.

Two-member compound. Castiello is the Aragonese form of Latin castellum ('small fortress, castle'), with the diphthongisation e > ie characteristic of the Aragonese language, parallel to Castilian castillo but with preservation of the -ll- group without full palatalisation. De Jaca is a locative genitive that links the fortress to the seigneury of the nearby episcopal city and distinguishes it from many other Castiellos of Upper Aragón.

Pre-Roman toponym of Iberian or Vasconic origin. The form Iaca appears already in the 1st century BC in the texts of Strabo and Pliny the Elder as the name of the capital civitas of the Iaccetani people (Iacetanos), described by Strabo as one of the Vasconic-Iberian groups of the central Pyrenees. The root iak- or iac- has not been linked with certainty to any modern Vasconic lexical term, but the concentration of Pyrenean toponyms in iaca- and iaco- suggests a homogeneous pre-Roman substrate.

Hagiotoponym formed by Sancta Caecilia ('Saint Cecilia'), a Roman invocation widely spread in Pyrenean repopulation, plus the locative genitive de Jaca that places the village under the seigneury of the regional centre. The form Cilia, proper to medieval Aragonese, maintains the palatalised pronunciation of Caecilia without the diphthongisation that Castilian imposed on Cecilia.

Three-member compound. Santa Cruz is a Christian invocation (Latin Sancta Crux); de la Serós derives from the Latin sororum ('of the sisters'), genitive plural of soror ('sister'). The popular Aragonese form Serós collectively names the nuns of the old Benedictine female monastery of the place, whose 11th-century Romanesque church of Santa María gave name to the whole complex.

Toponym of probable Vasconic-pre-Roman origin, linked to the Pyrenean substrate prior to Romanisation. The most sustained philological hypothesis derives it from the Basque harri ('stone, rock') with locative suffix -tz/-es, yielding approximately harritze > arrés with the meaning 'stony place, quarry'. The description fits the village's setting: an isolated rocky outcrop above the Aragón valley, dominated by limestone protrusions.

Pre-Roman toponym of disputed etymology. The hypothesis with most support derives it from an Ibero-Vasconic base *rost- or *rust- with the value of 'crag, rocky slope', also present in toponyms such as Rusticán, Rostán, Rosta, distributed throughout the central Pyrenees and prepyrenees. Other authors propose a pre-Latin origin linked to the Aragonese term ruesta ('slope, steep incline'), descriptive of the village's location on the southern flank of the Sierra de Peña.

Two-member compound. Undués, of probable Vasco-pre-Roman origin undatze ('place of waters, spring'), from the lexeme unda or uhar ('water, stream') plus locative suffix -tze. De Lerda, a locative that distinguishes this Undués from another Pyrenean Undués (Undués Pintano) by reference to the contiguous place of Lerda, an old associated term.

Toponym of disputed etymology. The philological hypothesis with most support —⁠Mitxelena, Salaberri⁠— derives it from old Basque zangoza ('place of feet, crossroads'), from the lexeme zango ('foot, base, foundation') plus locative suffix, a description that fits the village's historical setting at the confluence of the Pyrenean roads and the Aragón valley.

Transparent pre-Roman Basque toponym Ilunberri, compound of ilun ('dark, shadowy') and berri ('new'), with the meaning of 'new place of the shadowy valley' or, according to alternative interpretation, 'new town' —⁠iri ('city') plus berri⁠—⁠. The form Ilumberri is attested on Celtiberian coins and on Latin inscriptions as the name of the indigenous civitas prior to Romanisation; Lumbier is its Romance evolution with loss of the initial i- and simplification of the -nb- group.

Transparent Romance composition Mons Regalis ('royal mountain, king's mountain'), applied to the fortified hill at the foot of which the village grew by initiative of the Navarrese Crown. The foundation dates from King Sancho VII the Strong around 1198, on the site of a previous settlement known as Elo, a Vasco-pre-Roman toponym of disputed etymology.

Toponym of disputed etymology. The hypothesis with most support —⁠Mitxelena, Salaberri⁠— derives it from old Basque teba or tepa ('low hill, knoll, gently elevated terrain') with the Romance plural suffix -as, designating the gentle elevations on which the nucleus sits. The medieval form Thebas suggests a pronunciation with initial aspiration that Navarrese Romance lost.

Anthroponymic derived from the Germanic name Henricus (Latinisation of Frankish Haimirich, 'prince of the household', from haim 'home' and rich 'powerful'), adapted to old Basque with locative suffix -itz yielding Eneritz, 'place of Henry'. It designates a medieval settlement founded or linked to a character named Henry, probably a 12th-century feudal lord.

Transparent Romance compound. Ponte is Galician for 'bridge' (Latin pons, pontis); Maceira, 'apple tree', derives from the Latin mattiana ('apple of the mattiana variety', so named in the 1st century by the agronomist Caius Matius). The toponym describes the place with literalness: the medieval bridge of the Tambre surrounded by apple trees planted in the river meadows, Galician agrarian landscape documented in the cartulary of San Martín Pinario from the 12th century.

Toponym derived from the Latin Nigraria ('dark place, shadowy area'), formed on the adjective niger ('black, dark') with the locative suffix -aria. The most sustained interpretation associates it with the colour of the Tambre in this stretch enclosed between hills —⁠the river runs deep under closed forest and keeps its dark tone in the sun⁠—⁠. A second hypothesis derives it from the colour of the quartzites that outcrop on the surrounding slopes.

Transparent Romance compound. Vila, from the Latin villa ('country house, rural estate'), generalised in late Latin as appellative for a small population centre; Serío, of disputed etymology, with two parallel hypotheses: Latin anthroponym Serius (Roman cognomen attested in Hispanic epigraphy) or derivative of Latin serius ('late, evening-like'), applied to agricultural farms with a late cycle.

Descriptive toponym, from the Latin pinna ('feather' in original meaning, 'crag, battlement, pointed rock' through metaphorical evolution), with the Galician feminine article a prefixed. The Galician form pena preserves the meaning common to all peninsular Romance languages: high rock, rocky outcrop, rocky crest. The name describes the granite outcrop that dominates the hamlet's surroundings.

Toponym of pre-Roman base *Olbeira or *Olveira, a hydronymic root of the Indo-European family *albh- ('clear, white water') also present in Atlantic toponyms like Olbia (Sardinia), Albia (Italy) or Alba (Scotland). The suffix -oa is the Galician continuation of Latin -ola with diminutive or locative value. The medieval form Olveyroa is attested from the 12th century in cartularies of the monastery of San Xusto de Toxosoutos.

Toponym derived directly from the Latin hospitalis ('hospitable, for guests'), applied in the Middle Ages to pilgrim hostels at critical passes of the Camino. The noun hospitalis (domus) gave hospital as the name of the building. In this case, the toponym fossilises an old pilgrim hospital documented from the 14th century, located at the exact point where the Camino branches towards Fisterra or towards Muxía.

Pre-Roman toponym of disputed etymology. The hypothesis with most support —⁠Edelmiro Bascuas⁠— derives it from an Indo-European hydronymic base *sek- or *sak- ('current, watercourse, spring') with locative suffix -i-, yielding approximately *Sakia > Cee. Other authors have proposed a pre-Greek origin Kaia ('shore'), though without solid documentary support. The form Cee, without Romance diphthongisation, reflects the early Galician palatalisation of the initial k before a palatal vowel.

Toponym of disputed origin. Three parallel hypotheses concur: a) pre-Roman base *kurk- or *kork- ('rock, crag, rocky promontory'), with augmentative Romance suffix -ón; b) Latin anthroponym Corcubius in the function of villa owner; c) medieval maritime denomination Curvus Sinus ('curved bay'), descriptive of the meander that forms the ría. The medieval form Corcobión is attested from the 11th century.

Toponym derived from sardiña (Latin sardina, 'sardine'), plus the Galician locative suffix -eiro (from the Latin -arius) of professional or instrumental value. It means 'place where sardines are fished or salted', a habitual designation on the Galician coast for seasonal tuna trap settlements and salt-curing factories. The form Sardineiro, without accent, preserves the proparoxytone Galician pronunciation.

Transparent Latin toponym Finis Terrae ('end of the earth'), fixed by the Roman geographers of the 1st century to name the westernmost known cape of Gallaecia. The native Galician form Fisterra preserves the pronunciation of the compound without the phonetic Castilianisation Finis > Finis, while the Castilian Finisterre adds the final paragogic -e. Both forms coexist in current official documentation, with Galician institutional preference for Fisterra.

Pre-Roman hydronym of disputed etymology. Bascuas's hypothesis derives it from a paleo-European base *lir- or *ler- of the Indo-European family *lei- ('to flow, spring, pour water'), present in Atlantic hydronyms like Welsh Llŷr (sea), Irish Lir (sea god) or Portuguese Lis. The plural suffix -es is the Latinised mark of the Galician locative generic. The hamlet gives its name to the small ría where the homonymous river flows.

Toponym of double philological hypothesis. The interpretation with most support derives it from late Latin monachia ('monastery, community of nuns'), through the medieval Galician form monxía, with palatalisation -nx- > -x- and simplification of the compound. The toponym would commemorate the old female Benedictine monastery documented at the site from the 11th century. The alternative pre-Roman hypothesis links it to a base *muk- ('rock, crag') common to Atlantic orographic toponyms.

Toponym derived from late Hispanic Latin robula, diminutive of robur ('oak', properly 'hard wood'), applied in Leonese toponymy as a descriptive appellative for spaces populated by young oak groves or small oak forests. The definite article La, prefixed, reflects the fixation of the toponym as a proper place name from the late medieval period.

Three-member compound. Pola, in medieval Leonese and Asturian, derives from the Latin populus ('people, community') by particular phonetic evolution, and specifically designates a free village founded by royal charter between the 12th and 14th centuries. De Gordón is a locative genitive that places the pola in the historical territory of Gordón, an anthroponym derived from the Latin Gordius (cognomen of the Roman gens Gordiana) with the Romance augmentative suffix -ón.

Pre-Roman toponym homonymous with the Occitan Tolosa (Toulouse), attested on both sides of the Pyrenees since Antiquity as a common toponymic base. The philological hypothesis with most support —⁠Joan Coromines, Joaquín Gorrochategui⁠— derives it from a pre-Roman base *tol- or *tol-os- of the Indo-European family with the value of 'elevation, mass, mountain', also present in Atlantic hydronyms like Tola, Toledo and in Pyrenean oronyms like Toll. The current Basque form Tolosa preserves the toponym without phonetic alteration.

Compound Basque toponym. Beasain, according to the most sustained hypothesis —⁠Koldo Mitxelena, Patxi Salaberri⁠—⁠, derives from bea- (reduced form of behe, 'lower part, bottom') plus the locative suffix -zain ('guardian, custodian'), with the approximate sense of 'place of the lower-part guard' or 'valley watch post'. The denomination describes the strategic position of the town, founded in the 14th century as a control point of the Oria river corridor.

Basque toponym of disputed etymology. The hypothesis with most support —⁠Mitxelena, Salaberri⁠— derives it from the base zegi or zegama, linked to a pre-Roman root *sek- or *seg- with hydronymic or orographic value (also present in toponyms like Segura, Segama, Sego), plus the Basque locative suffix -ama of abundantial value. It designates the hamlet enclosed at the foot of Aizkorri (1,532 m, highest point of Gipuzkoa) at the headwaters of the Oria river.

Double toponym. Salvatierra, in Castilian, is a Romance composition of salvus ('safe, free') plus terra ('land'), applied by the Castilian kings to walled urban foundations with defensive function. Agurain, the previous Basque name, is of disputed etymology: Mitxelena's hypothesis derives it from the pre-Roman anthroponym Agur- with the Basque locative suffix -in. Both names coexist in current official signage, with Alavese institutional preference for Agurain.

Double toponym. Vitoria is the Castilian name imposed by King Sancho VI the Wise of Navarre upon founding the walled town in 1181: from the Latin victoria ('victory'), commemorating, according to the 13th-century chronicle of Rodrigo Ximénez de Rada, a victory of the Navarrese king over the Castilian armies. Gasteiz, the previous Basque name, derives from the medieval anthroponym Gastei (Basque form of Castellus) with the Basque locative suffix -iz, designating 'place of Gastei' —⁠the original pre-foundational hamlet⁠—⁠.

Three-member compound. La Puebla, from late Latin populare through medieval Castilian, designates an urban foundation with charter granted by the Crown. De Arganzón is a locative genitive derived from the pre-Roman anthroponym Arganzius (variant of Argentius) with the Vasconic locative suffix -on. The original hamlet received the anthroponym of the early medieval owner; the Puebla is a later refoundation by Alfonso VIII of Castile in 1191.

Toponym of disputed etymology. The hypothesis with most support derives it from the Latin pannus curvus ('curved cloth, folded canvas'), a metaphorical description of the limestone walls of the gorge that curve on both sides of the Oroncillo riverbed forming a natural 'cloth'. The medieval attested form Pancurvo (10th century) supports this etymology. A second hypothesis derives it from a pre-Roman anthroponym Pancorbus, without clear documentary support.

Pre-Roman toponym of Celtiberian origin attested in 1st-century Roman sources. The Latinised form Virovesca, cited by Pliny the Elder and Ptolemy, designated the capital civitas of the Autrigones, a Celtiberian people of the upper Ebro valley. The most sustained Celtiberian etymology —⁠Joaquín Gorrochategui⁠— derives the name from *wiros ('man, male, warrior') plus *upo-isk- ('lower place') or hydronymic variant, with the approximate sense of '(city) of the men of the lower place'.

Three-member compound. Monasterio, from the Latin monasterium (Christian Hellenism from monastērion, 'place of solitary monks'), applied by early medieval toponymy to villages of monastic origin. De Rodilla, of disputed etymology: the most sustained hypothesis derives it from the Latin rotella, diminutive of rota ('wheel'), applied to circular geographical features —⁠in this case the conical elevation of San Vicente hill on which the nucleus sits⁠—⁠. A second hypothesis links it to the pre-Roman anthroponym Roditta.

Toponym of double convergent filiation. The pre-Roman base matrice, from the Latin matrix ('matrix, riverbed, mother-watercourse'), named the main spring of the locality. The Berber conquest of 711 introduced the Arabic form Mayrīṭ (مَجْريط), from the root mağrà ('watercourse, water conduction') plus the locative suffix -īṭ borrowed from Hispanic Romance. The two etymologies describe the same hydrographic reality —⁠the density of springs in the Madrid subsoil⁠— and converge in the current form.

Descriptive toponym of modern Castilian. The compound Tres Cantos refers to the three stone markers (cantos, in old Castilian, 'natural unworked stone') that historically marked one of the vertices of the municipal term of Colmenar Viejo, from which the current municipality segregated in 1991. The urban foundation of the satellite city is from 1971: one of the youngest toponyms with municipal entity in Spain.

Compound toponym. Colmenar is a derivative of Latin columnaris ('proper to columns') or, according to the more sustained philological hypothesis, of pre-Roman *culumena ('honeycomb, container for bees') with the Castilian locative suffix -ar, designating 'place of beehives'. The epithet Viejo, added in the 15th century, distinguishes this Colmenar from other homonymous municipalities of the Madrid surroundings (Colmenar de Oreja, Colmenar del Arroyo).

Compound toponym. Manzanares is a pre-Roman hydronym of disputed etymology: the hypothesis with most support —⁠Coromines, Galmés de Fuentes⁠— derives it from an Iberian base *mantia ('watercourse, river') plus locative suffix, without etymological relation to the fruit manzana (apple) despite the phonetic coincidence. El Real, added in the 14th century, refers to the Castilian royal domain of the place after the donation of the seigneury by King John I to the Marquis of Santillana in 1383.

Toponym derived from the Latin ceresetum with diminutive suffix, 'small cherry orchard', formed on cerasum ('cherry tree'). The compound designates a discreet grove of cherry trees, a frequent formation in the transition forests between Meseta holm oak and Guadarrama pinewood and beech grove. The diminutive form, irregular in Castilian —⁠Cercedilla instead of the expected Cerezuela⁠—⁠, reflects an early fixation of the toponym in late Hispanic Latin.

Transparent two-member compound. Fuenfría, Romance contraction of fuente fría ('cold spring'), designates the icy spring that emerges at the col at 1,796 metres, headwater of the Guadarrama river. The syncopated agglutinated form is characteristic of medieval Castilian; it coexists with the full form Fuente Fría in parallel toponyms of the Central System. The noun puerto, from the Latin portus ('mountain pass, gorge'), extends metaphorically to high mountains the original maritime sense of the term.

Celtiberian toponym attested from the 2nd century BC. The form Segouia appears on Celtiberian coins with legend in northeastern Iberian alphabet, in Pliny the Elder (III, 27) and Ptolemy (II, 6, 56). The most sustained etymology —⁠Joaquín Gorrochategui, Carlos Jordán⁠— derives it from the Celtic compound *sego-uia, 'place of victory' or 'strong city', from the root *segh- ('strength, victory, dominion') plus the suffix *-uia ('place'). Cognate with other Celtiberian toponyms in Sego-: Segeda, Segobriga, Segontia.

Four-member compound. Santa María is the Marian invocation of the apparition that founded the place; la Real refers to the royal patronage of the sanctuary; de Nieva is the pre-Roman toponym of the hamlet on which the monastery was raised. The base Nieva, of disputed etymology, probably derives from the Indo-European root *nei- ('to flow, spring') or *neig- ('watercourse'), of paleo-European origin, also present in the toponyms Nieves, Nievas and in the Asturian hydronym of the Nalón river.

Pre-Roman toponym attested from the 2nd century BC as Cauca, capital of the Vaccaei according to Roman sources (Titus Livius, Appian, Pliny the Elder). The most sustained etymology —⁠Joaquín Gorrochategui, Francisco Villar⁠— derives it from an Indo-European base *kauk- with the value of 'elevation, rounded height, prominence', compatible with the geographical position of the Vaccaean oppidum on the Eresma river meseta. The Castilian form Coca preserves the toponym with the sole transformation of the final vowel loss characteristic of peninsular Romance.

Transparent Arabic toponym. Alcazarén derives from Andalusian Arabic al-qaṣrayn (القَصْرَيْن), dual form of the noun al-qaṣr ('the castle, the fortress', in turn a loan from the Latin castrum). The dual suffix -ayn, characteristic of Arabic but exceptional in Hispanic toponymy, designates the existence of two castles —⁠probably two 9th-century Muslim fortlets on the Duero frontier⁠—⁠. It figures among the few peninsular toponyms that preserve the dual mark of Arabic.

From the Latin ulmetum, “elm grove”: a collective of ulmus “elm” with the suffix -etum of abundance, the one behind Spanish -edo (robledo “oak grove”, pinedo “pine grove”). Olmedo names the old elm wood of the Tierra de Pinares.

Toponym of debated etymology with three main hypotheses: a) Arabic balad al-Walīd ('territory of Walid'), from the Berber anthroponym of the founder of the first Muslim settlement on the Pisuerga; b) Latin Vallis Olit ('valley of Olid'), Arabic anthroponym Romance-adapted; c) Latin Vallis Tolitum ('valley of Toledo'), from the Visigothic period. The Arabic hypothesis, sustained by Federico Corriente, Joan Coromines and Jaime Oliver Asín, is the most accepted by contemporary philology.

Two-member compound. Medina, from the Arabic madīna ('city, urban settlement with own jurisdiction'), Arabism of wide use in peninsular toponymy. De Rioseco, transparent Latin compound río + seco ('dry river'), refers to the Sequillo river (small dry river) that crosses the town with pronounced dry season from July to October. The toponym thus designates a madīna identified by its intermittent watercourse, in opposition to other peninsular Medinas (Medina del Campo, Medina-Sidonia).

Three-member compound. Villalón, transparent Romance, derives from villa (Latin, 'country house, rural estate') plus anthroponym in augmentative suffix -ón applied to an early medieval Lubo or Lupus ('wolf') —⁠compositional pattern common to Villalobón, Villalonso, Villalumbroso⁠—⁠. De Campos places the town in the Tierra de Campos, historical cereal region of the Central Meseta.

Pre-Roman Celtiberian toponym attested in Roman sources as Septimanca, cited by Pliny the Elder (III, 27) and by the Antonine Itinerary as a Vaccaean civitas of the middle Pisuerga valley. The most sustained etymology —⁠Francisco Villar, Joaquín Gorrochategui⁠— derives it from the Celtic base *septim- ('seventh') plus the suffix *-anca of abundantial-locative value, with the approximate sense of 'the seventh' (stage, mile or settlement) in the Celtiberian road network.

Unique hagiotoponym in Spain derived from the Germanic anthroponym Wamba, Visigothic king of the Hispani between the years 672 and 680. The Germanic base *wamba means 'belly, womb, broad abdomen' in Gothic and other western Germanic languages, originally attributed as a descriptive nickname. The toponym commemorates the tradition that places the king's burial in the Mozarabic church of Santa María of the place after his deposition and monastic confinement by Ervig in 680. It counts among the few peninsular toponyms with directly attested Germanic etymology.

Hagiotoponym deformed by Romance agglutination of the Latin phrase Sanctus Gervasius ('Saint Gervasius'), 1st-century Milanese martyr patron of Lombard Christianity and, by extension, of Gallo-Roman Christianity of the Late Empire. The phonetic evolution Sancti Gervasii > Santervas, with loss of intervocalic consonant and palatalisation of the -rv- group, is regular in medieval Asturleonese and Leonese. The epithet de Campos places the town in the cereal Tierra de Campos.

Transparent Castilian compound mata + el pino ('pine scrubland' or 'pine low-forest'). The base mata, from late Hispanic Latin matta of probable pre-Roman Celtic origin *mattos ('terrain covered with scrub, low forest'), describes the forest formation characteristic of the mountain foothills before the dense pinewood.

Toponym of disputed etymology. The hypothesis with most support derives it from the Basque zamar ('sheep fleece, short curly wool', base of Castilian zamarra) plus a locative suffix -mala or -amala of uncertain filiation, probably pre-Roman. The toponym would originally name a sheep livestock fold, pastoral function that the hamlet maintained from the Middle Ages on the high Eresma pastures.

Descriptive toponym of medieval Castilian, locative plural of Latin hortus ('garden, vegetable plot, enclosed cultivated space'). It designates the small Segovian hamlet settled on the irrigated meadows of the Eresma river, already documented in the 12th century as vegetable gardens dependent on the Segovia cathedral chapter.

Pre-Roman toponym of disputed etymology. The hypothesis with most support —⁠Joaquín Gorrochategui, Francisco Villar⁠— derives it from a Celtiberian base *anneā of hydronymic value, linked to the Indo-European root *an- ('water, spring'), also present in peninsular toponyms such as Anna (Valencia), Aniana and the Atlantic hydronyms of the Aña-, Ane- group. It designates the small Eresma meadow hamlet settled on a constant spring.

Two-member compound. Nava, a pre-Roman word documented in all peninsular languages with the sense of 'plain between mountains, enclosed meadow, depression covered with grass', of probable Vasco-Aquitanian origin (modern Basque naba, 'plain'). De la Asunción, Marian invocation of the parish church added in the 16th century to distinguish this Nava from dozens of peninsular namesakes.

Compound toponym. Vill- is a reduced form of villa ('country house, rural estate') followed by the Germanic anthroponym Egilo or Egidio with diminutive suffix -illo. The compound designates 'small estate of Egilo/Egidio', a hamlet of old Visigothic or early medieval domain.

Descriptive compound. Puente, from the Latin pons ('bridge'), and Duero, pre-Roman hydronym of the river attested in Roman sources as Durius (Pliny, Strabo), from the Indo-European base *dheuro- ('flow with force, abundant river'). The toponym names the historical Duero crossing south of Valladolid where the Roman road XXIV crossed the river.

Three-member compound. Peña Flor, transparent Romance from the Latin pinna ('crag, raised rock') plus florida ('flowery, covered with flowers'), describes the limestone mass on which the nucleus sits. De Hornija, pre-Roman hydronym of the eponymous stream, linked to the Indo-European root *urn- of hydronymic value ('current, spring'), distinguishes this Peñaflor from other peninsular ones.

Transparent Romance compound from the Latin castrum ('fortified camp, military fort') plus monte ('elevation, wooded mountain'), literal description of the location of the old Celtiberian castro on the hill that dominates the Hornija valley. The toponym commemorates the survival of the pre-Roman fortified enclosure in the micro-region.

Toponym of disputed etymology. The hypothesis with most support derives it from a pre-Roman base *berr- of Vasco-Aquitanian filiation with the value of 'scrubland, terrain covered with watercress or ferns', also present in Cantabrian and Basque toponyms like Berrueta, Berriobeiti, Berrón. The Latinised plural suffix -ueces fixes the medieval form attested from the 11th century.

Two-member compound. Cuenca, from the Latin concha ('mollusc shell, concave vessel'), applied in Hispanic toponymy with an extended orographic sense of 'natural depression of the terrain, hollow surrounded by elevations'. De Campos places the town in cereal Tierra de Campos and distinguishes it from Cuenca of Cuenca, eponymous head city.

Transparent Romance compound. Fonti-, reduced form of Latin fons, fontis ('fountain, spring'), followed by hoyuelo, diminutive of Castilian hoyo ('depression, hollow'). The compound means 'small fountain of the hollow' or 'fountain of the hollow', a description of the spring that emerges in the natural depression on which the nucleus sits.

Toponym of disputed etymology. The philological hypothesis with most support —⁠Mitxelena, Salaberri⁠— derives it from the Basque bal(a) ('round, curved, oval', dialectal Basque word preserved in balau, 'curved cord') plus locative suffix -aseda of pre-Roman origin linked to the hydronymic *sed-. The approximate sense would be 'curved place of the spring' or 'meander of the flowing water', a description that fits the bend of the Cadagua river on which the historical centre sits. The medieval attested form is Valmaseda (1199), with the V reflecting the Basque bilabial pronunciation.

Two-member compound. Medina, from the Arabic madīna ('city'), a common toponymic Arabism of the Christian repopulation of the Burgalese Bureba. De Pomar, derived from the Latin pomarium ('apple orchard, orchard of fruit trees'), refers to the historical region of Pomar de Valdivielso —⁠documented from the 10th century as a zone of apple orchards dependent on the Oña monastery⁠—⁠.

The form Vivanco, without locative suffix, originally designates 'estate or property of Vivancus', a compositional pattern common to other Burgalese toponyms like Villasante, Villalain or Villarcayo. It preserves the fossilised genitive of the Latin anthroponym.

Pre-Roman toponym of disputed etymology. The hypothesis with most support derives it from a pre-Roman base *bon- of hydronymic or orographic value linked to the Vasco-Aquitanian substrate of the Esla valley.

Diminutive toponym derived from the Latin rivulus ('small river, stream'), diminutive of rivus ('river, watercourse'), with the Asturleonese suffix -iello characteristic of western Romance diphthongisation. It designates the hamlet settled on the upper meander of the Omaña river, in one of the deepest valleys of the Leonese Maragatería.

Transparent toponymic Arabism. Aldea, from Andalusian Arabic ad-day‘a ('the hamlet, the small rural nucleus', from the root dāʿa 'to be lost, scattered'), a common Arabism of peninsular lexicon that passed to Castilian as a generic name.

Latin toponym attested from the year 14 BC as Caesaraugusta, Roman foundation of Emperor Augustus as immune colony of Italic law, settled on the Iberian oppidum of Salduie. The Castilian form Zaragoza derives by phonetic evolution from the Arabic name Saraqusṭa, adaptation of the Latin Caesaraugusta to the Arabic phonological system (loss of the initial e, simplification of the -rs- consonantal group, preservation of the final suffix).

Pre-Roman toponym attested in Roman sources as Alaun (Antonine Itinerary), Iberian civitas of the middle Ebro valley also cited by Pliny the Elder.

An unresolved etymology. The one secure element is the suffix -anza (from the Latin -antia), a pre-Roman formant abundant in the toponymy of the northwest; the root Priar- still lacks a firm explanation.

A debated etymology. The best-supported reading links it to the Latin meta / metula 'conical heap' —⁠whence the Galician meda, a haystack⁠—⁠, after the pinnacles the mine left behind; others trace it to medulla 'marrow', the hollowed-out interior of the mountain, or to the Mons Medullius of the Asturian wars.

From the Latin pontem 'bridge' —⁠after the stone bridge over the river Cabrera that gave rise to the town in the 13th century⁠— followed by the personal name Domingo Flórez, of the Flórez lineage, 'son of Froila'.

Barco has a double reading —⁠from the pre-Roman *barc- 'hollow' or from the word barca, 'boat', after the ferry over the Sil⁠—⁠; Valdeorras is not 'valley of gold' but 'valley of the gigurri', the Asturian people Pliny called Gigurri.

From the Latin Villa Martini 'the villa —⁠the rural estate⁠— of Martín', on the personal name Martinus; the addition de Valdeorras places it in the valley of the gigurri and distinguishes it from other Vilamartín.

From the Latin ruga —⁠'furrow, fold' and, in late Latin, 'street, road'⁠—⁠: the town born along the road. The same word gives Galician and Portuguese rúa and Italian ruga.

Of disputed origin: from a Latin personal name Petinius —⁠the estate of a certain Petinius⁠— or from a reference to a 'set stone', a boundary marker or milestone of the Roman road. Neither reading has consensus.

A transparent compound: Galician monte furado 'pierced mountain', from the Latin montem foratum. The name is literal: a Roman tunnel perforates the mountain to divert the Sil and take its gold.

A debated etymology: from Galician queiruga / queiroga 'heather' —⁠a place of heathland⁠— or from a pre-Roman base, perhaps hydronymic, that the oldest forms seem to require.

Pobra, from the Latin populare 'to settle, to found a chartered town', recalls a medieval foundation by charter; Brollón goes back to the personal name Braulione, attested as early as 1050.

From the Latin Mons Fortis 'strong, fortified mount' —⁠the hill of San Vicente that crowns the town⁠—⁠; Lemos preserves the name of the lemavi, a pre-Roman Galician people.

From the Latin (terram) plantatam '(land) planted or driven in', past participle of plantare —⁠Galician chantar, 'to drive in'⁠— with the shift pl- > ch-. It is debated whether it names a plantation or a stockade of driven stakes.

A debated etymology, from the Latin rota 'wheel' with the suffix -arium: 'road of cart-tracks', or a place of wheelwrights, or —⁠by another path⁠— a pre-Roman hydronym tied to running water.

From the Latin riparia 'riverbank, shore', feminine of riparius (from ripa, 'bank'): the town facing the ría de Arousa. The -b- of the official spelling is the regular Galician voicing of the Latin -p-.

Pobra, from the Latin populare 'to settle' —⁠a 'puebla', a medieval foundation⁠—⁠; Caramiñal, 'place of caramiñas', after the camariña (Corema album), the shrub endemic to the Atlantic coast.

Of unresolved origin. The Real Academia Galega's own Seminar on Onomastics calls it an 'enigma': several hypotheses circulate —⁠a budetum 'reed-bed', a pre-Roman root, a Suevic settlement⁠— and none has been proven.

From the Latin rivum angulum 'the bend of the river', after the angle the coast of the ría de Arousa makes on passing. The reading is probable and widespread, though no onomastic study has sealed it.

Of unfixed etymology, probably of a pre-Roman stratum. The district's toponymy is one 'of names in the water' —⁠the Ulla marshes, the place names in -bre⁠— but Dodro itself still lacks a firm etymon.

From the Latin Bracara Augusta, 'the Bracara of Augustus': the name of the pre-Roman bracari people joined to that of the emperor who founded the city. Braga is the contraction of Bracara.

From the Latin portella, diminutive of porta: 'the little gate', the low pass that opens the Gerês range; followed by do Homem, 'of the river Homem', whose valley the road climbs.

The río Caldo, from the Latin calidus 'hot', after its thermal waters; the baths are those of the Roman mansio of the Via Nova, long read as Aquis Originis.

It is not 'wolf'. Lobios is the plural of lobio —⁠the trellis, the vine raised over the path⁠—⁠, from the Germanic *laubja 'shelter, gallery'. Friar Sarmiento already clarified it in 1754.

From the Latin corticata, on cortex 'bark'; the sense is debated —⁠'the bark-covered', an enclosure, or a place of stripping bark⁠—⁠. Pliny already named an insula Corticata.

From the Latin ripa Aviae, 'the bank of the Avia': the town at the confluence of the river Avia with the Miño. Avia is a pre-Roman hydronym, from the old water-root *av-.

Pazos, from the Latin palatium 'palace, manor house' —⁠the Galician pazo⁠—⁠; Arenteiro, from the river, the old Argentarium, 'the silver one', after its silvery sands.

A possessor toponym: from the genitive of the Germanic personal name Viaricus, '(the estate) of Viaricus'. It is one of the many Galician names in -riz that fix the owner of an old holding.

A plant-name: from codeso —⁠the shrub Adenocarpus⁠— plus the collective suffix -eda (from the Latin -eta): 'the codeso-ground', the place where the codesos abound.

From the Latin muros, 'the walls': a plural toponym, after the walls of an old fortification —⁠or the stone arcades that still form its seafront⁠—⁠.

From the Galician outo 'high' (from the Latin altus), the same family as outeiro, 'hillock': 'the heights', after the coastal high ground where A Serra de Outes sits.

A pre-Roman name, from an old water-root *noig- 'to wash', fitting an estuary site. Its resemblance to Noah (Noé) fed a legend —⁠the ark run aground on Monte Aro⁠— but it is folk etymology, not philology.

From the Celtic *briga 'fortified height, hillfort', with loss of the intervocalic -g-: 'the fort'. Not from the Galician brión 'moss', which is a homonym.

A pre-Roman hydronym from the root *am- 'water, river': 'the place of waters', the same origin as the valley of A Maía and the pre-Roman people of the amaei.

Of disputed etymology: from the Gallaecian theonym Bandua —⁠a pre-Roman deity worshipped in the region⁠— or from the genitive of a Latin personal name, '(the estate) of Bandus'.

From the Latin cella nova, 'the new cell': the monastery that San Rosendo founded in 935. Cella was the monastic cell —⁠or granary⁠—⁠; nova, new.

From the Galician merca 'purchase' (from the Latin mercari, 'to trade'): 'the trading', after the historic fair that gave rise to the town at a crossroads.

From the Latin (villa) Beati, 'the estate of Beatus': a possessor toponym, from the Latin name Beatus 'happy, blessed', over an old holding in the Ribeiro.

From the Galician leiro 'plot of tilled land' (masculine of leira), from a pre-Roman base *laria: the terraced vineyard plots that carpet this bank of the Avia, heart of the Ribeiro.

Of unresolved etymology. The Real Academia Galega proposes recovering the form Aboborás, which would link it to abóbora, 'pumpkin/gourd' —⁠a place of gourd-fields⁠— but there is no firm etymon.

From the Galician barreiro 'clay-pit, mudflat' (from barro, 'clay', plus the suffix -eiro), in the plural: 'the clay-pits', the places where clay was dug.

From the Latin fauce 'throat, jaws', applied to a river's mouth: 'the mouth of the river', here that of the Masma into the Cantabrian Sea. Not to be confused with hoz 'sickle', of another root.

Of unresolved origin. The Real Academia Galega rejects the popular explanations —⁠burel (coarse cloth or heraldic band), the buoy⁠— and points to a personal name, without fixing the etymon.

Of disputed etymology: from the Latin cervus 'deer' —⁠an animal toponym⁠— or from a pre-Roman base *(s)kerbh- 'sharp, cutting', which would make it a name of the terrain.

From the Latin Iovis, '(consecrated to) Jupiter': probably a villa Iovii over an old Roman cult of the god. Iove > Xove, with the Galician x-.

From the Latin urticaria 'place of nettles' (from urtica, 'nettle'): a plant-name, 'the nettle-ground'. It names the largest ría of the north Galician coast.

From the Latin cetaria 'salting factory, fishery of great fish' (from cetus, 'cetacean, large fish'): a Roman name of the fishing coast.

It is not 'valley of wine'. Valdoviño comes, on the best-argued reading, from the Germanic personal name Baldovino —⁠the estate of a certain Baldovino⁠—⁠; another makes it Val de Aviño, on a pre-Roman hydronym.
