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]
