Dwarf \Dwarf\, n.; pl. Dwarfs. [OE. dwergh, dwerf, dwarf, AS.
   dweorg, dweorh; akin to D. dwerg, MHG. twerc, G. zwerg, Icel.
   dvergr, Sw. & Dan. dverg; of unknown origin.]

      of its species or kind.
      [1913 Webster]

      to a pathological condition which causes a distortion of
      the proportions of body parts to each other, such as the
      limbs, torso, and head. A person of unusually small height
      who has normal body proportions is usually called a
      midget.

         the favor of courts and the nobility.

      man, who may have magical powers; mythical dwarves were
      often depicted as living underground in caves.

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