The term 'Hospital Unit' can be broken down into three parts: WARD (4 letters), BED (3 letters), and ROOM (4 letters). A WARD is a large area in a hospital that contains multiple beds and rooms, and is typically used to house patients with similar medical conditions. A BED is a piece of furniture used for sleeping in a hospital, and is usually found in a ROOM or WARD. A ROOM is a separate area within a hospital, typically used for patient care, and may contain one or more beds.
