         conscience, and to remonstrate against any growing
         corruptions in practice, and especially in principles.
                                                  --Waterland.

   Syn: Expostulate, Remonstrate.

   Usage: These words are commonly interchangeable, the
          principal difference being that expostulate is now
          used especially to signify remonstrance by a superior
          or by one in authority. A son remonstrates against the
          harshness of a father; a father expostulates with his
          son on his waywardness. Subjects remonstrate with
          their rulers; sovereigns expostulate with the
