具 is a bound form (b.f.), meaning it almost always appears as part of a two-character word rather than alone. The two most common families of meaning are (1) a tool or utensil, as in 工具 (tool), 家具 (furniture), or 玩具 (toy), and (2) the sense of possessing or having, as in 具备 (to possess) or 具有 (to have). The character also appears in 具体 (concrete, specific), a very common word where the original meaning has become abstract.
