The word "vault" traces back to the Latin volta, the feminine form of volutus ("arched" or "curved"), derived from volvere ("to roll"). This reflects the architectural sense of a curved ceiling. The verb meaning "to leap" emerged in the 16th century, likely influenced by the idea of an arched movement during a jump. The financial storage sense evolved from the physical security of arched strongrooms.
