      of its species or kind.
      [1913 Webster]

   2. Especially: A diminutive human being, small in stature due
      to a pathological condition which causes a distortion of
      the proportions of body parts to each other, such as the

      who has normal body proportions is usually called a
      midget.

         below the usual or normal size; as, a dwarf pear tree;
