Reconstruction:Proto-Celtic/trei

This Proto-Celtic entry contains reconstructed terms and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.

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”).
