Etymologically, the entry records: From Middle English smothe, smethe, from Old English smēþe, smōþ, both from Proto-West Germanic *smanþī, of unknown origin. Cognate with Scots smuith (“smooth”), Saterland Frisian smoud (“smooth”), Low German smood and smödig (“smooth, malleable, ductile”),… 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 smooth, spelled S-M-O-O-T-H, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
