   OHG. bannan to summon, fr. ban ban. See {Ban} an edict, and
   {Finish}, v. t.]
   1. To condemn to exile, or compel to leave one's country, by
      authority of the ruling power. ``We banish you our
      territories.'' --Shak.

   2. To drive out, as from a home or familiar place; -- used
      with from and out of.

            How the ancient Celtic tongue came to be banished
            from the Low Countries in Scotland.   --Blair.

   3. To drive away; to compel to depart; to dispel. ``Banish
      all offense.'' --Shak.

   Syn: To {Banish}, {Exile}, {Expel}.

   Usage: The idea of a coercive removal from a place is common
          to these terms. A man is banished when he is forced by
          the government of a country (be he a foreigner or a
          native) to leave its borders. A man is exiled when he
          is driven into banishment from his native country and
          home. Thus to exile is to banish, but to banish is not
          always to exile. To expel is to eject or banish,
          summarily or authoritatively, and usually under
          circumstances of disgrace; as, to expel from a
          college; expelled from decent society.
