Etymologically, the entry records: From Middle English occasioun, from Middle French occasion, from Old French occasiun, from Latin occāsiōnem, noun of action from perfect passive participle occāsus, from verb occidō, from prefix ob- (“down", "away”) + verb cadō (“fall”). 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 occasion, spelled O-C-C-A-S-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
