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.

Borrowed from Middle French volter (“to turn or spin around; to frolic”), borrowed from Italian voltare, itself from a Vulgar Latin frequentative form of Latin volvere; later assimilated to Etymology 1, above.
