sentences:  Vendler comments on the intention of the rhyme scheme, claiming that Shakespeare as a poet is conscious of grammatical and syntactic possibility as "ingredients of invention" and he "routinely, but not idly, varies tense, mood, subject-position, and clause-patterns in order to make conceptual or rhetorical points".Vendler acknowledges Shakespeare's art within words and claims that any variation to the rhyme scheme is intended to add purpose to the poem itself.Paul Edmondson and Stanley Wells also argue that varying rhyme scheme is intentional but is not necessarily premeditated to attach further symbolism to the speaker's words.
