Action Verbs vs. Linking Verbs
Action verbs show exactly what the subject is doing in a sentence. When you read "My cat purrs loudly" or "My dog barks at the mailman," the words purrs and barks tell us the action happening. They're easy to spot because you can picture the subject performing something.
Linking verbs work differently - they don't show action but instead connect the subject to information about it. In "I am hungry," the verb "am" links "I" to the description "hungry." Since "hungry" describes the subject, it's called a predicate adjective. In "Mrs. Weiler is my teacher," the verb "is" connects Mrs. Weiler to "teacher," which is a predicate noun.
Remember this: Action verbs show what subjects DO, while linking verbs show what subjects ARE.
Sometimes words that normally show action can function as linking verbs. This happens when they're used to connect rather than show physical action.
