("fit," or "proper"), in Judaism, the fitness of an object for ritual purposes. Though generally applied to foods that meet the requirements of the dietary laws (kashruth), kosher is also used to describe, for instance, such objects as a Torah scroll, water for ritual bathing (mikvah), and the ritual ram's horn (shofar). When applied to food, kosher is the opposite of terefah ("forbidden"); when applied to other things, it is the opposite of pasul ("unfit").
