Huts, cots, SHACKS, SHANTIES, and HOVELS are all terms used to describe temporary or primitive dwellings. Cots are small beds, usually made of metal, that can be folded up for storage. SHACKS are small, often crudely built structures, typically made of wood or other materials. SHANTIES are even more primitive dwellings, often made of scrap materials. HOVELS are the most basic type of dwelling, typically consisting of a single room with no windows or doors. All of these terms are used to describe dwellings that are not permanent or luxurious.
