Predicate (grammar)

The predicate in traditional grammar is the second part of a clause or sentence, the first being the subject.A good introduction is: Crystal, David 1995. The Cambridge encyclopedia of the English language. Cambridge University Press, p220.  A predicate completes an idea about the subject, such as what it does or what it is like.Allerton D. 1979. Essentials of grammatical theory. London: Routledge & Kegan Paul.Huddleston, R. 1988. English grammar: an outline. Cambridge, UK: Cambridge University Press.

The subject NP is shown in green, and the predicate VP in blue.

There is a quite different theory of sentence structure, called dependency structure grammar. This puts the finite verb (= conjugated verb) as the root of all sentence structure. It rejects the binary NP-VP division.
