Proto-Slavic

*аzь (Leuciscus idus)

Etymology

From Proto-Balto-Slavic *āˀźis (“goat”), cognate with Lithuanian ožỹs (“billy-goat”), Latvian āzis (“buck”). Further akin to Proto-Indo-Iranian *Haȷ́ás (“goat”). Probably from Proto-Indo-European *h₂eǵ- or *h₂eyǵ- (“goat”) (whence Ancient Greek αἴξ (aíx, “goat”)).

For the semantic shift in Slavic, compare Proto-Slavic *byčьkъ (“roach”) from Proto-Slavic *bykъ (“bull”) or German Ziege (“sabrefish”) from primary meaning goat. The original meaning is preserved in the derivative *azьno (“goat skin”).

Noun

*azь m

billy goat → Leuciscus (genus of fish)
