What are Auxiliary Verbs?
Auxiliary verbs, also known as “helping verbs,” are used to provide additional information about the main verb in a sentence. They help to express tense, voice, mood, and aspect of the main verb. In English, there are two types of auxiliary verbs: primary and modal.
The Three Primary Auxiliary Verbs
The primary auxiliary verbs in English are “to be,” “to have,” and “to do.” These verbs are used to form various tenses, voice, and aspect. Let’s examine each of these primary auxiliaries in detail.
To Be
