Etymologically, the entry records: From Middle English institucioun, from Old French institution, from Latin institūtiō, from instituō (“to set up”), from in- (“in, on”) + statuō (“to set up, establish”). Equivalent to institute + -ion. 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 institution, spelled I-N-S-T-I-T-U-T-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
