Action verb or linking verb?

Is it an action verb or a linking verb? Some verbs can be used as action verbs and linking verbs in different sentences.

Action verbs are usually easier to use and understand. Action verbs show activity or movement.

  • Example: I kick the ball.

    In this example, the action verb is kick. Kick is a movement.

Linking verbs connect the subject of the sentence to information about that subject.

  • Example: I am happy.

    In this example, the linking verb is am. Am connects the subject (I) to information about the subject (happy). Am is a "to be" verb.

Verbs that deal with the senses are sometimes used as action verbs and sometimes used as linking verbs. (senses = taste, touch, smell, hear, see)
