In traditional
grammar, a predicate is one of the two main parts of a
sentence (the other being the
subject, which the predicate modifies). In current
linguistic semantics, a predicate is an expression that can be true of something. Thus, the expressions "is yellow" or "like broccoli" are true of those things that are yellow or like broccoli, respectively. The latter notion of a predicate is closely related to the notion of a predicate in
formal logic, and includes more expressions than the former one, like, for example,
nouns and some kinds of
adjectives.
