The term 'Welcome Site' can be broken down into three words: MAT (3 letters), DOORMAT (7 letters), and DOOR (4 letters). A MAT is a piece of material, usually made of fabric or rubber, that is used to cover a floor or other surface. A DOORMAT is a type of MAT that is placed outside or inside a DOOR to help keep dirt and debris from entering a building. A DOOR is an opening in a wall, doorframe, or other structure that allows access to and from a room or building. Together, these three words form the phrase 'Welcome Site, ' which is often used to describe a place where visitors are welcomed.
