The word 家具 (jiājù, meaning "furniture") is formed by combining the character 家 (jiā), which means "home" or "household", with the character 具 (jù), which means "tool", "implement", or "utensil". The concept is created through this direct semantic pairing: 具 specifies the category of objects as utilitarian items, while 家 immediately places and confines those items to the domestic sphere. Thus, the compound logically and visually represents the "implements of a home", which is the essential idea of furniture.
