οἶς

See also: ὄϊς, -οις, and οἷς

Ancient Greek

Contracted form of ὄϊς (óïs), from Proto-Hellenic *ówis, from Proto-Indo-European *h₂ówis. Cognate with Sanskrit अवि (ávi), Latin ovis, and Old English eowu (English ewe). Apparently a doublet of κῶας (kôas) via Anatolian.

Synonyms: πρόβατον (próbaton), ἀρήν (arḗn)
