[Middle English mondeine, from Old French mondain, from Latin mundānus, from mundus, world.] mun·dane'ly adv., mun·dane'ness, mun·dan'i·ty (-dān'ĭ-tē) n.
1475, from M.Fr. mondain (12c.), from L. mundanus "belonging to the world" (as distinct from the Church), from mundus "universe, world," lit. "clean, elegant"; used as a transl. of Gk. khosmos (see cosmos) in its Pythagorean sense of "the physical universe" (the original sense of the Gk. word was "orderly arrangement"). L. mundus also was used of a woman's "ornaments, dress," and is related to the adj. mundus "clean, elegant" (used of women's dress, etc.).
