Etymologically, the entry records: From halcyon, from Latin Alcyone, from Ancient Greek Ἀλκυόνη (Alkuónē), daughter of Aeolus and wife of Ceyx. When her husband died in a shipwreck, Alcyone threw herself into the sea whereupon the gods transformed them both into halcyon birds (kingfishers). … Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is halcyon days, spelled H-A-L-C-Y-O-N- -D-A-Y-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
