errach

Old Irish

Etymology

Pedersen derives this from Proto-Celtic *wesrakos, an enlargement of Proto-Celtic *wesr-, from Proto-Indo-European *wósr̥. Compare Latin ver (“spring”). Stifter disputes this; he and Schrijver before him^[1] point out that **ferach would be expected. Wagner, and Stifter after him instead derive it from the precursor of Middle Irish err (“hind”), the semantics derived from spring being the "tail-end" of winter.^[2]
