This document discusses predicates and predicators. It defines a predicate as any word or sequence of words that can function as the predicator of a sentence. A predicator is the semantic role played by a word or words in a particular sentence. Predicates can be of various parts of speech, while predicators are specific to individual sentences. Predicates are also classified by their degree - the number of arguments they typically take, such as one-place, two-place or three-place predicates.
