      [1913 Webster]

   Syn: To charge; blame; censure; reproach; criminate; indict;
        impeach; arraign.

   Usage: To Accuse, Charge, Impeach, Arraign. These
          words agree in bringing home to a person the
          imputation of wrongdoing. To accuse is a somewhat
          formal act, and is applied usually (though not
          exclusively) to crimes; as, to accuse of treason.
          Charge is the most generic. It may refer to a crime, a
          dereliction of duty, a fault, etc.; more commonly it
          refers to moral delinquencies; as, to charge with
          dishonesty or falsehood. To arraign is to bring (a
          person) before a tribunal for trial; as, to arraign
          one before a court or at the bar public opinion. To
          impeach is officially to charge with misbehavior in
          office; as, to impeach a minister of high crimes. Both
          impeach and arraign convey the idea of peculiar
          dignity or impressiveness.
          [1913 Webster]
