Tui
Tuy
PontevedraGalicia
Pre-Roman toponym attested in classical sources as Tude or Tyde, with no established linguistic affiliation. Hypotheses oscillate between a Celtic root and an earlier substrate; none has been confirmed.
Tude appears in Pliny the Elder's Naturalis Historia and Ptolemy's Geographia as one of the civitates of the grovii, a pre-Roman people of the lower Miño. The two main hypotheses contest its origin. The first proposes an Indo-European root teutā- 'people, tribe' —the same that gives the name Teutons—, consistent with a tribal frontier settlement. The second posits an earlier non-Indo-European substrate, without firm parallels in peninsular onomastics. The Celtic affiliation is the most widely accepted in contemporary Galician onomastics, although no author considers it demonstrated. The intervocalic Latin d, preserved in Tude and Tudae, was already lost in medieval Galician-Portuguese; the forms Tuy (Castilian) and Tui (modern Galician) are phonetically identical.
