Decided \De*cid"ed\, a.
   1. Free from ambiguity; unequivocal; unmistakable;
      unquestionable; clear; evident; as, a decided advantage.
      ``A more decided taste for science.'' --Prescott.

   2. Free from doubt or wavering; determined; of fixed purpose;
      fully settled; positive; resolute; as, a decided opinion
      or purpose.

   Syn: {Decided}, {Decisive}.

   Usage: We call a thing decisive when it has the power or
          quality of deciding; as, a decisive battle; we speak
          of it as decided when it is so fully settled as to
          leave no room for doubt; as, a decided preference, a
          decided aversion. Hence, a decided victory is one
          about which there is no question; a decisive victory
          is one which ends the contest. Decisive is applied
          only to things; as, a decisive sentence, a decisive
          decree, a decisive judgment. Decided is applied
          equally to persons and things. Thus we speak of a man
          as decided in his whole of conduct; and as having a
          decided disgust, or a decided reluctance, to certain
          measures. ``A politic caution, a guarded
          circumspection, were among the ruling principles of
          our forefathers in their most decided conduct.''
          --Burke. ``The sentences of superior judges are final,
          decisive, and irrevocable. --Blackstone.

      struggle, by giving the victory to one side or party; to
