ABSTRACT
In this chapter I attempt to develop a theory which accounts in an insightful way for a number of semantic and syntactic peculiarities of those classes of ES which crucially involve the occurrence of the verb be. The verbal class, which poses problems of quite a different sort and about which I have far less to say, will be dealt with in chapter 7. Accordingly, throughout this chapter the term ES will be taken to comprise only the ontologicals, locationals, and periphrastics.
