Etymologically, the entry records: From late Middle English congestioun, from Old French [Term?], from Latin congestĭō (“heap, accumulation”), from congerō (“to bring together, accumulate, heap up”), formed by the root gerō (“to carry”) and the prefix con-. 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 congestion, spelled C-O-N-G-E-S-T-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
