| 释义 | cache (once / 2621 pages) 1nv 2n Cache sounds like what it is, a stash, and sometimes people — usually the criminal type — have a cache of stolen cash. Often the phrase "weapons cache" is used of a bunch of hidden guns or weapons that have been hidden or stored away, which is logical, given that the French verb cacher means "to hide."

So a cache is anything from a stash of cash to a store of information on reserve.
