Here's a breakdown:
* Linking verbs connect the subject of a sentence to a word or phrase that renames or describes the subject. Common linking verbs include: *be* (am, is, are, was, were, been, being), *appear*, *become*, *feel*, *look*, *seem*, *smell*, *sound*, *taste*.
* Predicate nominative is the noun or pronoun that follows a linking verb and renames or identifies the subject.
Example:
* My favorite author *is* Stephen King.
* "My favorite author" is the subject.
* "is" is the linking verb.
* "Stephen King" is the predicate nominative, renaming the subject.
