Hopsack → The word 'hopsack' is formed from 'hop' (from Middle English *hoppen*, meaning to leap or spring) and 'sack' (from Old English *sæcc*, meaning a bag or pouch). The term refers to a bag made for carrying hops, which are used in brewing.
Think of 'hopping' ('hop') to carry something in a 'bag' ('sack') — that's why hopsack refers to a bag used for hops.
