Alkyóne comes from alkyón (ἀλκυών), which refers to a sea-bird with a mournful song[7] or to akingfisher bird in particular.[8] The meaning(s) of the words is uncertain becausealkyón is considered to be of pre-Greek, non-Indo-European origin.[9] However,folk etymology related them to theháls (ἅλς, "brine, sea, salt") andkyéo (κυέω, "I conceive"). Alkyóne originally is written with asmooth breathing mark, but this false origin beginning with arough breathing mark (transliterated as the letter H) led to the common misspellingshalkyón (ἁλκυών) andHalkyóne (Ἁλκυόνη),[10] and thus the name of one of the kingfisher birdgenus' in EnglishHalcyon. It is also speculated that Alkyóne is derived fromalké (ἀλκή, "prowess, battle, guard") andonéo (ὀνέω, fromὀνίνεμι,onínemi,[11] "to help, to please").[12]
