Pronunciation

  • IPA (Classical): [ˈhaɫ.ky.oːn][1]
  • IPA (Ecclesiastical): [ˈal̠ʲ.t͡ʃi.on][1]

Forms

halcyōn f (genitive halcyonis); third declension[1] More often spelled alcyōn, genitive -onis.[2][3]

Etymology

It is borrowed from Ancient Greek ἀλκυών (alkuṓn, “kingfisher, halcyon”), also spelled ἁλκυών (halkuṓn), a word of unknown origin.[2][1][4] Etymonline thinks the explanation from ⟨háls⟩ “sea” and ⟨kúōn⟩ “conceiving” is probably an ancient folk etymology for a borrowing from a non-Indo-European language.[4]

Earliest recorded meaning

Gaffiot cites Virgil's Georgics.[3] Köbler dates Virgil 70–19 BC.[5]

Semantic evolution

It was a bird wrongly identified with the kingfisher, which the ancients believed nested on the sea, the halcyon; in Propertius the plural stands for seabirds in general.[2] The adjective alcyonidēs (diēs) named the halcyon days, the calm days when it was thought to breed.[2][4]

British Medieval Latin used it for a seabird, a gull.[6] Middle English had alcioun in the late 14th century, and halcyon dayes (1540s) translates the Latin.[4]

Timeline

  • 70–19 BC – Virgil uses it.[3][5]
  • 57/46–12 BC – Propertius uses it of seabirds.[2][5]
  • 1540s – English halcyon days is recorded.[4]
