originFrom Middle English *bevel, from Anglo-Norman *baivel (whence obsolete French beauveau) a diminutive of Old French baïf (“open-mouthed”), perhaps from baer (“to gape”), from Medieval Latin *batāre (“to gape, yawn, be open”), probably of imitative origin. If so, then related to Italian badare.
