Origin: 1425–75; < Latin mundānus, equivalent to mund(us) world + -ānus-ane; replacing late Middle English mondeyne < Middle French mondain < Latin, as above
late 15c., 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.). Related: Mundanity.
