Definition & Meaning of "predicate noun"

What is a "predicate noun"?

A predicate noun is a noun that follows a linking verb and provides information about the subject of the sentence. It renames or identifies the subject, often serving to complete the meaning of the verb. Predicate nouns are typically found in sentences with linking verbs such as "is," "are," "was," or "were." For example, in the sentence "She is a teacher," the predicate noun "teacher" identifies and describes the subject "she." Another example is "The winner is John," where "John" renames the subject "the winner." Understanding predicate nouns is important for recognizing how they function in sentences to clarify the identity or role of the subject.
