Forms

κύκνος (kúknos) m (genitive κύκνου); second declension[1]

Etymology

It is perhaps inherited from Proto-Indo-European *(s)keuk- (“to shine, be white”), the swan being named after its colour.[2][1][3] The root is reconstructed in this form by Lubotsky; it was formerly written *ḱeuk-.[2] Cognate with Sanskrit शोचति (śócati, “to shine, glow”) and Sanskrit शुक्र (śukrá, “bright, white”).[2][1] Wiktionary adds that the name could also imitate the swan's call.[1]

Earliest recorded meaning

It is found from Homer on.[2][4] The Iliad compares the Greek army to flocks of long-necked swans in a meadow.[5][6]

Semantic evolution

The swan was sacred to Apollo and famous for its song, and it was said to sing most beautifully before its death.[7][5] In Aeschylus' Agamemnon a woman is said to have sung her last lament “like a swan”, and later epigrams call a poet a swan.[5]

By its curved shape the word named a kind of ship, after its prow, and by its white colour an eye-salve in Galen.[5][2] Latin borrowed it as cycnus.[8] Medieval Greek kept the word, and in Modern Greek κύκνος (kýknos) is a learned form of the ancient word.[9][10]
