Ultimate origin
Ancient Greek (κύκνος)

Pronunciation

  • Classical: [ˈkyk.nʊs][1]
  • Ecclesiastical: [ˈt͡ʃik.nus][1]

Forms

cycnus m (genitive cycnī); second declension[1] Manuscripts and editions often have cygnus.[2][3] Horace scans the first syllable short.[2]

Etymology

It is borrowed from Ancient Greek κύκνος (kúknos, “swan”).[2][3][1][4] Köbler tentatively connects the Greek word with Pokorny's root Proto-Indo-European *kan- (“to sound, sing”).[5] Isidore says that the swan, called ⟨olor⟩ in Latin, took this name from singing, because it pours out sweet song.[4]

Earliest recorded meaning

Köbler dates it from Lucretius,[5] who asks how a swallow could compete with swans.[2]

Semantic evolution

It is the swan, famous for its song, above all its dying song, and sacred to Apollo, as in Cicero and Pliny the Elder.[3][2] Virgil has owls competing with swans.[2] In augury it was a favourable omen: Virgil has twelve swans rejoicing in a flock.[2] Swans also draw the chariot of Venus or of love poets, as in Propertius and Ovid.[2] Figuratively it is a poet, especially a singer.[1] Church Latin glosses it swan.[6] English cygnet (c. 1400) is a diminutive of cigne, from the Latin form ⟨cygnus⟩.[7]
