Etymologically, the entry records: From Middle English mouthful, mouth-full, mouthe full, from Old English *mūþfull, from Proto-West Germanic *munþafull, equivalent to mouth + -ful. Compare Dutch mondvol (“mouthful”), German Mundvoll (“mouthful”), Danish mundfuld (“mouthful”), Swedish munful… 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 mouthful, spelled M-O-U-T-H-F-U-L, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
