Predicate Noun:
* Definition: A predicate noun renames the subject of the sentence. It follows a linking verb (like "is," "are," "was," "were," "seems," etc.).
* Example: "She is a popular singer." Here, "popular singer" renames the subject "she."
Predicate Adjective:
* Definition: A predicate adjective modifies the subject of the sentence. It also follows a linking verb.
* Example: "The movie was popular." Here, "popular" describes the subject "movie."
To determine which it is, look for the subject and the linking verb in the sentence. If the word after the linking verb renames the subject, it's a predicate noun. If it describes the subject, it's a predicate adjective.
