di-

dis- dis- (?; 258) 1. A prefix from the Latin, whence F. d['e]s, or sometimes d['e]-, 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. [1913 Webster]

Note: Walker's rule of pronouncing this prefix is, that the s ought always to be pronounced like z, when the next syllable is accented and begins with ``a flat mute [b, d, v, g, z], a liquid [l, m, n, r], or a vowel; as, disable, disease, disorder, disuse, disband, disdain, disgrace, disvalue, disjoin, dislike, dislodge, dismay, dismember, dismiss, dismount, disnatured, disrank, disrelish, disrobe.'' Dr. Webster's example in disapproving of Walker's rule and pronouncing dis-as diz in only one (disease) of the above words, is followed by recent ortho["e]pists. See {Disable}, {Disgrace}, and the other words, beginning with dis-, in this Dictionary. [1913 Webster]

2. A prefix from Gr. di`s- twice. See {Di-}. [1913 Webster] ||
