Words related to pocket

poke (n.1)

"small sack," early 13c., probably from a merger of Old English pohha (Northumbrian poha, pocca) "bag, pocket" and Old Norse poki "bag, pouch, pocket," influenced by Old North French poque (12c., Old French poche) "purse, poke, purse-net," which is probably from Germanic. All of them probably are from Proto-Germanic *puk- (source also of Middle Dutch poke, dialectal German Pfoch), from PIE root *beu-, an imitative root associated with words for "to swell" (see bull (n.2)). Compare pocket.
