家具 (jiā jù) is a compound noun meaning 'furniture' — items used in homes or offices to make spaces functional and comfortable, such as chairs, tables, beds, and cabinets. The first character 家 (jiā) means 'home' or 'family', and the second character 具 (jù) means 'tool', 'implement', or 'article'. Together, they literally convey 'home implements' — objects that equip or furnish a living space.

This word is always used collectively and uncountable in Chinese; you don’t say *one furniture* or *two furnitures*. To specify quantity, use measure words like 套 (tào, 'set') or 件 (jiàn, 'item'), e.g., 一套家具 (a set of furniture) or 三件家具 (three pieces of furniture). It’s commonly used in contexts related to home decoration, moving, interior design, and shopping — never for outdoor or industrial equipment.
