The word "vault" has several meanings depending on its context. Primarily, it refers to a secure space or room, typically used for storing valuables, such as money, documents, or important items, often made of strong materials to prevent theft. Additionally, "vault" can refer to an arched structure that forms a ceiling or roof, commonly seen in architecture. In a different context, it can also refer to the act of jumping or leaping over something, typically using one’s hands or arms for support, as in gymnastics or athletics.
The word "vault" comes from the Latin word "volta," meaning "a turn" or "a curved structure." This word evolved into the Old French term "volte," which described an arched or curved structure. The transition into English retained the meanings related to both a secure place (like a strongroom) and an arching form.
