          according to the objects to which they are applied.
          Fracture is applied to hard substances; as, the
          fracture of a bone. Rupture is oftener applied to soft
          substances; as, the rupture of a blood vessel. It is
          also used figuratively. "To be an enemy and once to
          have been a friend, does it not embitter the rupture?"
