Whaet is the definishion of predicate nomitiv?

Answer 1

Just a little spelling first. The sentence should be written, "What is the definition of a predicate nominative?"

Predicate refers to belonging or being, such as the verbs is, are, were, etc.

Nominative refers to a noun.

There are predicate adjectives, such as "The sky was grey." The predicate adjective grey describes the subject sky.

Or predicate nominatives, such as "John and I are musicians" or "It is I." The predicate nominative is a noun or pronoun which refers to, or is a substitute for, the subject.
