tarsno

Old Irish

Alternative forms

tarsnu

Etymology

A derivative of Proto-Celtic *taras (“across”, preposition) (whence tar, dar), from Proto-Indo-European *terh₂-. Originally probably a yo-stem, but the expected nominative/accusative *tarsnae is unattested, the dative tarsno, tarsnu taking its place.
