Adjectives that modify or describe a sentence's or clause's subject and are connected to the subject by a connecting verb are known as predicate adjectives.
The word's root, nominative, is named. Thus, the subject is given a new name by the predicate nominee. Only when a linking verb follows, is there a predicate nominative.
It is a predicate nominative when the word or phrase that comes after a connecting verb renames the subject.
