- oidhche (obsolete)
From Old Irish aidche, from (virtual, i. e., mechanically reconstructed, not actually expected) Proto-Celtic *adakʷiā, arisen (likely only within Old Irish) through analogy (paradigm split) from the genitive singular (*adakʷiăs) of Old Irish adaig, from Proto-Celtic *adakʷī; from Proto-Celtic *ad (from Proto-Indo-European; possibly cognate with Latin āter (“dark”) and Sanskrit (compare Hindi अंधा (andhā, “blind”))) + *akʷiā (from Proto-Indo-European *akʷ; possibly cognate with Lithuanian ãklas), although the first element could also be from the preverb *ad- (from Proto-Indo-European *ád, cognate with Latin ad (“at”)) and the phonological shape of the second element is unclear and not necessarily Proto-Celtic *akʷ: the vowel is ambiguous, and the consonant need not be labialised.
oíche f (genitive oíche, plural oícheanta)
