The word 别墅 is formed by combining two characters: 别, which means "separate" or "another", and 墅, which means "country house" or "villa". Together, they conceptually create the idea of a "separate house" , specifically, a secondary, often luxurious residence located away from one's primary, everyday dwelling. This term inherently carries a sense of retreat, leisure, and space, distinguishing it from a main urban home and placing it conceptually in a scenic or suburban setting.
