Displaced native Middle English adle, audle (“disease”) (from Old English ādl (“disease, sickness”), see adle), Middle English cothe, coathe (“disease”… 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.
