Origin

From Middle English controllen, from Old French contrerole, from Medieval Latin contrārotulus (“a counter-roll or register used to verify accounts”), from Latin contrā (“against, opposite”) + Medieval Latin rotulus, Latin rotula (“roll, a little wheel”), diminutive of rota (“a wheel”). Partly displaced native Old English wealdan and Old English wieldan, whence their merged reflex English wield.
