   1. In a different manner; in another way, or in other ways;
      differently; contrarily. --Chaucer.

            Thy father was a worthy prince, And merited, alas! a
            better fate; But Heaven thought otherwise.

   2. In other respects.

      am engaged, otherwise I would accept.

         substitute for the opposite of a previous adjective,
         noun, etc.
