pouch

English pouch comes from Middle English pouche or poche, borrowed from Old Northern French pouche (Old French poche, puche). That in turn traces to Frankish *poka, a Germanic word for a pouch or bag, related to Middle Dutch poke and Old English pohha.

The word passed from a Germanic root through Frankish into Old French, then crossed into English via the Norman French dialect spoken after the Conquest, keeping essentially the same meaning of a small bag the whole way.

Pouch is a doublet of poke, since both descend from the same Old French poche/puche pairing; it's also related to pocket.
