Schoolmaster \School"mas`ter\, n.
   1. The man who presides over and teaches a school; a male
      teacher of a school.

            Let the soldier be abroad if he will; he can do
            nothing in this age. There is another personage
            abroad, -- a person less imposing, -- in the eyes of
            some, perhaps, insignificant. The schoolmaster is
            abroad; and I trust to him, armed with his primer,
            against the soldier in full military array.
                                                  --Brougham.

   2. One who, or that which, disciplines and directs.

            The law was our schoolmaster, to bring us unto
            Christ.                               --Gal. iii.
                                                  24.
