Etymology

From Middle English vaute, vowte, from Old French volte (modern voûte), from Vulgar Latin *volta < *volvita or *volŭta, a regularization of Latin volūta (compare modern volute (“spire”)), the past participle of volvere (“roll, turn”). Cognate with Spanish vuelta (“turn”) and Portuguese volta ("turn"). Doublet of volute.
