     Usage: These words denote different kinds of breaking,
            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

            also used figuratively. "To be an enemy and once to
            have been a friend, does it not embitter the rupture?"
            --South.
