A room is one of the separate sections or parts of the inside of a building. Rooms have their own walls, ceilings, floors, and doors, and are usually used for particular activities. You can refer to all the people who are in a room as the room .

If you talk about your room, you are referring to the room that you alone use, especially your bedroom at home or your office at work.

A room is a bedroom in a hotel.

If you room with someone, you share a rented room, apartment, or house with them, for example when you are a student.

If there is room somewhere, there is enough empty space there for people or things to be fitted in, or for people to move freely or do what they want to.

If there is room for a particular kind of behaviour or action, people are able to behave in that way or to take that action.

If you have room for manoeuvre, you have the opportunity to change your plans if it becomes necessary or desirable.
