Our generated misspelling index lists 9 likely wrong-spelling variants for Missouri, with forms such as "imssouri", "misosuri", and "misouri".

It also participates in 1 confusable-pair relationship, "Missoula", where similar look or sound leads writers to substitute one word for another in context.
Etymologically, the entry records: From a French adaptation of Miami wimihsoorita (“the people who have dugout canoes”), a term for the inhabitants of the area around the Missouri River. 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 Missouri, spelled M-I-S-S-O-U-R-I, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
