1. What are Auxiliary Verbs?
Auxiliary verbs, also known as “helping verbs,” play a crucial role in constructing grammatically correct sentences in English. They assist the main verbs by adding extra meaning or indicating tense, mood, voice, or aspect. Auxiliary verbs work in conjunction with main verbs to convey precise information. Without them, sentences may lack clarity and precision.
2. Types of Auxiliary Verbs
2.1 “Be” Verbs
The verb “be” is one of the most common auxiliary verbs in English. It serves various functions, such as indicating the state of being, forming the continuous tenses, and constructing passive voice sentences. The three forms of “be” verbs are:
- am, is, are: used for present tense
- was, were: used for past tense
- been: used in perfect tenses
Examples:
- She is a doctor. (present tense)
- They were playing soccer. (past tense)
- He has been to Paris. (present perfect tense)
2.2 “Have” Verbs
The verb “have” functions as an auxiliary verb when used to form perfect tenses or express possession. It indicates that an action has been completed or is ongoing.
- has, have: used for present tense
- had: used for past tense
Examples:
- I have seen that movie. (present tense)
- She has finished her homework. (present tense)
- They had already left when I arrived. (past tense)
2.3 “Do” Verbs
The verb “do” acts as an auxiliary verb in various situations, including forming negative and interrogative sentences, as well as adding emphasis. It is commonly used with the base form of the main verb.
- do, does: used for present tense
- did: used for past tense
Examples:
- Do you like ice cream? (present tense, interrogative)
- He doesn’t eat meat. (present tense, negative)
- We did our best. (past tense)

- can, could: indicate ability or possibility
- may, might: express possibility or permission
- must: convey necessity or strong obligation

3. FAQs about Auxiliary Verbs
Yes, some auxiliary verbs, such as “be,” can function as main verbs. For example:
- “He is a student.” (main verb)
