Etymologically, the entry records: From Middle English oughte, aughte, aȝte, ahte, from Old English āhte, first and third person singular past tense of Old English āgan (“to own, possess”), equivalent to owe + -t. Cognate with Sanskrit ईश्वर (īśvará, “capable of, liable”). 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 ought, spelled O-U-G-H-T, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
