vault 词源(Etymology) - 趣词词源[英文版]

vault [vault 词源字典]: vault: Vault ‘arched roof’ [14] and vault ‘jump’ [16] are distinct words, although they share a common ancestor: Latin volvere ‘roll, turn’ (source also of English involve, revolve, etc). Its feminine past participle volūta evolved in Vulgar Latin into *volta, which was used as a noun meaning ‘turn’, hence ‘curved roof’.

English acquired it via Old French voute or vaute. The use of vaulted ceilings in underground rooms led in the 16th century to the application of vault to ‘burial chamber’. Also from volvere came Vulgar Latin *volvitāre ‘turn a horse’, hence ‘leap, gambol’. This passed via Italian voltare and French volter into English as vault.
