Etymologically, the entry records: The adjective is derived from Middle English rash, rasch (“hasty, headstrong, rash”) [and other forms], probably from Old English *ræsċ (“rash”) (found in derivatives such as ræsċan (“to move rapidly; to flicker; to flash; to glitter; to quiver”), ræsċettan… 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.
