dis-

prefix meaning 1. "lack of, not" (e.g. dishonest); 2. "do the opposite of" (e.g. disallow); 3. "apart, away" (e.g. discard), from O.Fr. des-, from L. dis- "apart," from PIE *dis- "apart, asunder" (cf. O.E. te-, O.S. ti-, O.H.G. ze-, Ger. zer-). The PIE root is a secondary form of *dwis- and is thus related to L. bis "twice" (originally *dvis) and to duo, on notion of "two-ways, in twain." Dis has even stepped out on its own as a word (1980), as a shortening of disrespect or dismiss, originally in U.S. Black English, popularized by hip hop slang.
