Etymologically, the entry records: First attested in 1620–1630. Borrowed from French cooperation, from Late Latin cooperātiō. By surface analysis, co- + operation or cooperate + -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 cooperation, spelled C-O-O-P-E-R-A-T-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
