Etymology

Origin of vault¹

First recorded in 1300–50; Middle English noun vaut(e), vout(e), volt(e), volute, from Old French volte, vote, from unrecorded Vulgar Latin volvita, for Latin volūta, noun use of feminine past participle of Latin volvere “to turn”; verb derivative of the noun

Origin of vault²

First recorded in 1530–40; verb from Middle French volter “to leap,” from Old Italian voltare, from unrecorded Vulgar Latin volvitāre “to turn, leap”; the noun is derivative of the verb

Explanation

Vault is a verb that means "to jump over something." If you were hurrying out to the pasture to visit your favorite cow, you might vault over the gate in your excitement. When you support yourself with your hands as you jump over some hurdle, you vault, just as a gymnast might do across a vault — a piece of gymnastic equipment made to be vaulted over after a running start. Another meaning of vault is the arched roof of a building, or something that resembles such an archway. A storage chamber, especially one that's kept underground, is also a vault, like a bank vault.
