A cabinet was a private room in the houses and palaces of early modern Europe serving as a study or retreat, usually for a man. The cabinet would be furnished with books and works of art, and sited adjacent to his bedchamber, the equivalent of the Italian Renaissance studiolo. In the Late Medieval period, such newly perceived requirements for privacy had been served by the solar of the English gentry house, and a similar, less secular purpose had been served by a private oratory.

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.
