From The Collaborative International Dictionary of English v.0.48 :

  Deuto- \Deu"to-\or Deut- \Deut-\ (d[=u]t-)[Contr. from Gr.
     dey`teros second.] (Chem.)
     A prefix which formerly properly indicated the second in a

     sense as bi- or di-, although little used.
     [1913 Webster]

From The Collaborative International Dictionary of English v.0.48 :

  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]

From The Collaborative International Dictionary of English v.0.48 :

  Disserve \Dis*serve"\, v. t. [imp. & p. p. Di?????; p. pr. &
     vb. n. Disserving.] [Pref. dis- + serve: cf. F. desservir.]
     To fail to serve; to do injury or mischief to; to damage; to
     hurt; to harm.
     [1913 Webster]
  
           Have neither served nor disserved the interests of any
           party.                                   --Jer. Taylor.
     [1913 Webster]
