κύκνος

See also: Κύκνος

Ancient Greek

Perhaps from a Proto-Indo-European *ḱewk- (“white”), with cognates including Sanskrit शोचति (śócati) and शुक्र (śukrá), and possibly Old Norse Hǿnir (“god associated with swans and storks”). Could also be onomatopoeic from the sound of the swan's call (compare Russian кы-кы (ky-ky, “cry of a swan”)).
