ABSTRACT
This conclusion presents some closing thoughts of key concepts discussed in preceding chapter of this book. The book defines an analysis that bifurcates infinitival complements into reduced VP complements and unreduced IP complements. It presents syntactic evidence that constructions with pre-verbal causatives are bi-clausal, while those with post-verbal causes may be mono-clausal. Reduced constructions contrast with other infinitival constructions which exhibit only bi-clausal properties; these latter are unreduced constructions. The relevant bi- and mono-clausal properties of reduced constructions are summarized in Bi-clausal Properties and Mono-clausal Properties. The fact that the embedded clause of reduced constructions potentially has a full argument structure and even allows an overt subject, shows that there must be some way to represent a subject inside a reduced VP complement. The VP-internal subject hypothesis provides a convenient mechanism to accomplish this; this is not surprising, as Spanish causatives provided the initial motivation for this hypothesis.
