Verb Phrases

There are 3 types of verbs:

Action Verbs: represent the happening of what the subject does

Examples:  "I finally ^realized my mistake."
                    "She ^dances every Friday night."

Helping (Auxiliary) Verbs: Verbs often appear with helping verbs to give more insight on their meaning. The complete verb would be the main verb plus any used helping verbs.

Examples:  "Comets ^{have collided} with earth many times."
                    "Loren ^{had known} about the plan for some time."

Linking Verbs: do not express action, but a state of condition. They define what a subject is rather than what it does. They help the main action verb in a sentence and pertain to the five senses - seeing, tasting, touching, hearing and smelling - and how we understand the world. They link the subject with a word to offer more information.

Examples:  "My carpet still feels ^rough."
                    "Loren seems ^anxious about the test."
                    "Loren ^is an athlete."
                    "Loren ^was glad."
