means A small bag or flexible container used to hold or carry things, often closed by drawing it shut or folding it over.

from From Old French 'pouche' or 'poche,' a regional variant meaning bag or pocket — the same source that gave English 'poke' (as in 'a pig in a poke') and ultimately 'pocket,' its smaller diminutive cousin. The Old French itself is thought to come from a Germanic root for a swelling or bag, so the word has long described something that bulges with whatever you've stuffed inside.
