Etymologically, the entry records: From Middle English capitain, capteyn, from Old French capitaine, from Late Latin capitāneus, from Latin caput (“head”) (English cap). Ultimately from Proto-Indo-European *kap-. Doublet of chieftain, also from Old French. 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 captain, spelled C-A-P-T-A-I-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
