The term 'Put on the Wall' can be solved by two four-letter words: 'HANG' and 'Hung'. To HANG something means to attach it to a wall or other vertical surface using a hook, nail, or adhesive. It is often used to refer to the act of hanging a picture or painting on a wall. To hung something means to suspend it from a higher point, such as a hook or nail. This is usually done with heavier items, such as mirrors or shelves.
