Hidden or stored something away in a secret place, often for later use or to keep it safe.
From unknown origin, possibly related to Old French 'estache' (a pouch) or Slavic roots. First recorded in English around the 1700s as slang for hiding valuables.
Pirates stashed their treasure, Cold War spies stashed documents, and squirrels stash acorns using spatial memory so sophisticated scientists study it—'stash' is one of those words that connects crime, espionage, and nature's survival strategies. The word became so common in internet culture it now describes everything from hidden computer files to secret snack reserves.
