ABSTRACT
Another such relationship is modification. Thus, an attributive adjective is described as modifying the head noun (twinkling in the twinkling stars); so too, a prepositional phrase relative to a modifying verb (e.g. shine in the sky). In the modification structure the twinkling stars, twinkling can be dropped without changing the function of the stars in the larger construction. But in the complementation in the sky neither in or the sky can in general be deleted.
