Scavenger → The word originates from the Middle English 'scavager', which comes from the Old French 'esquavager' (meaning to collect or gather). It refers to a person who collects or gathers discarded items, often from waste.
Think of someone who 'gathers' ('esquavager') things that are 'discarded' — that's why a scavenger is someone who collects what others throw away.
