Predicates describe the identity, nature, character, characteristics and state of the subject. Predicates are usually served by nouns, adjectives, adverbs, prepositional phrases, gerunds, infinitives and clauses, and are usually located after verbs (be, become, apparent, seem, look, sound, feel, get, SME, etc.). If the predicative of a sentence is also acted by a sentence, then the sentence acting as predicative is called predicative clause.

The predicative in ing form should also be in ing form, and the predicative should also be infinitive when the subject is infinitive.
