Beanbag → The word is formed from "bean" (from Old English "bean", meaning a seed or legume) and "bag" (from Old Norse "baggi", meaning a sack or pouch). A beanbag is essentially a bag filled with beans or similar materials, used for seating or lounging.
Think of a 'seed' ('bean') inside a 'sack' ('bag') — that's what a beanbag is, a bag filled with beans.
