Wallpaper → It is formed from "wall" (from Old English *weall*, meaning a structure that encloses or divides) and "paper" (from Latin *papyrus*, meaning a material made from the pith of the papyrus plant used for writing). The word "wallpaper" refers to a material used to cover and decorate the walls of a room.
Think of a 'structure that encloses' ('wall') being covered with a 'writing material' ('paper') — that's why wallpaper is used to decorate walls.
