Proto-Celtic

Etymology

Suggested to be contracted from *trāē, from earlier *trāsē, dative singular of *trās, from earlier *trāns (“across”).
Alternatively, from pre-Celtic Proto-Indo-European *tr̥h₂éy, alternative form of *tr̥h₂és, both fossilized inflected forms of a root noun **térh₂s.
In either case, derived from the root *terh₂- (“to cross, go through”).
