1. VERBS

2. Two Main types of verbs
Action- Action verbs do exactly what the name implies. They show action to the sentence.
Linking- Linking verbs are more difficult. First, they do not show action. They link two parts in a sentence. They link the subject with either a noun or pronoun.
Example: His mother is an accountant.

3. Helping verbs Just as the name implies, helping verbs, sometimes called auxiliary verbs, help out the main verb in a sentence. They accomplish this by giving more detail to how time is portrayed in a sentence.
