The word 客厅 is formed by directly combining two meaningful characters: 客 (kè), meaning "guest" or "visitor", and 厅 (tīng), meaning "hall" or "large room". The concept is created by fusing these ideas together to denote the specific "hall for guests", which naturally defines the primary function of the room we understand as the living room or sitting room in a home. It is a straightforward conceptual blend where the purpose of the space is described by its designated users.
