Morphology

bank + vault

The meaning 'a secure room in a bank for storing valuables' is directly and compositionally derived from 'bank' (financial institution) + 'vault' (secure room for valuables). This is a regular noun-noun compound following common cross‑linguistic patterns, so a B1 learner who knows both constituents would understand it.

Etymology

Bank vault comes from the word vault, which once meant a very strong room, often with a curved roof, where people kept their valuables. That's why bank vault means the very secure room in a bank where money and important papers are kept 'safe'.
