room
ROOM/ruːm/
An enclosed part of a building for living or other activities.
The enclosed room contains a bed beneath a small window.

Etymology
Old English rum meant space generally, not necessarily an enclosed chamber. The meaning narrowed to a ship’s cabin and then to a space inside a building separated by walls or partitions.
In context
with the exception of the corridor outside the billiard room, the house was in darkness.
