A prefix from the Latin, whence F. des, or sometimes de-, dis-.
   The Latin dis-appears as di-before b, d, g, l, m, n, r, v, becomes
   dif-before f, and either dis-or di- before j. It is from the same root
   as bis twice, and duo, E. two. See Two, and cf. Bi-, Di-, Dia-.
   Dis-denotes separation, a parting from, as in distribute, disconnect;
   hence it often has the force of a privative and negative, as in disarm,
   disoblige, disagree. Also intensive, as in dissever.
