Auxiliary verbs are sometimes called the helping verbs because they work with the main verb in a sentence and “help it out”. Together, the auxiliary verb and the main verb form a unit. Here are some examples of sentences containing auxiliary verbs:
Steven is leaving and taking his football with him. How are we going to play now?
Her favorite team has finished at the top of the conference, so she is going to buy a team jersey. I hope she buys me one, too.
