            to express it to the eye.             --Holder.
      [1913 Webster]

   2. Style of writing or printing; handwriting; the peculiar

      [1913 Webster]

   10. One of the persons of a drama or novel.
       [1913 Webster]

   Note: "It would be well if character and reputation were used
         distinctively. In truth, character is what a person is;
         reputation is what he is supposed to be. Character is
         in himself, reputation is in the minds of others.
         Character is injured by temptations, and by wrongdoing;
         reputation by slanders, and libels. Character endures
         throughout defamation in every form, but perishes when
         there is a voluntary transgression; reputation may last
         through numerous transgressions, but be destroyed by a
         single, and even an unfounded, accusation or
         aspersion." --Abbott.
         [1913 Webster]
