A drawing room is a room in a house where visitors may be entertained, and an alternative name for a living room. The name is derived from the 16th-century terms withdrawing room and withdrawing chamber, which remained in use through the 17th century, and made their first written appearance in 1642. In a large 16th- to early 18th-century English house, a withdrawing room was a room to which the owner of the house, his wife, or a distinguished guest who was occupying one of the main apartments in the house could "withdraw" for more privacy. It was often off the great chamber and usually led to a formal, or "state" bedroom.

In a building or ship, a room is any enclosed space within a number of walls to which entry is possible only via a door or other dividing structure. The entrance connects it to either a passageway, another room, or the outdoors. The space is typically large enough for several people to move about. The size, fixtures, furnishings, and sometimes placement of the room within the building or ship support the activity to be conducted in it.
