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.
