what is meant by predicate noun ?and
what is predicate adjectives

[Casiopea]

Predicate nouns and predicate adjectives are subject complements. Subject complements complete the meaning of the subject. Certain verbs connect the subject complement to the subject:

appear become seem feel grow act look
taste smell sound get be (in all its forms)

Subject complements either rename the subject (predicate noun) or describe the subject (predicate adjective),

ex: Max is a teacher. <it's a noun: predicate noun>
ex: Max seemed happy. <it's an adjective: predicate adjective>
