Auxiliary Verbs are also known as “supporting verbs”. They are often placed before the main verb to help identify the time of an action, or to confirm, deny and question an action. They are also used to convert sentences from active to passive.
These auxiliary verbs are (am/is/are/was/were, do/does/did, have/has/had, will). The “am/is/are/was/were” auxiliary verbs are collectively called be-verbs.
For Example
When there are no main verbs, auxiliary verbs perform the actions of the main verbs, as in case of existence, being, status, nature, etc.
For Example
1. I am excited.
Answer Main Verb
Description This verb represents the only action in the sentence, hence it will be treated as a main verb.
2. The students do not know his name.
Answer Main Verb
Description This verb represents the main action in the sentence, with the other verbs supporting the main verb by describing the time when the action took place.
3. Ajay does all his homework at night.
Answer Main Verb
Description This verb represents the only action in the sentence, hence it will be treated as a main verb.
4. How much is the price of this book?
Answer Main Verb
Description This verb represents the only action in the sentence, hence it will be treated as a main verb.
5. Does he speak fluently?
Answer Main Verb
Description This verb represents the main action in the sentence, with the other verbs supporting the main verb by describing the time when the action took place.
6. They have a couple of pets.
Answer Main Verb
Description This verb represents the main action in the sentence, with the other verbs supporting the main verb by describing the time when the action took place.
7. What do musicians do for a living?
Answer Auxiliary Verb
Description This verb is doing only the support action of mentioning the time of the event. The action is being determined by the main verb.
1. The boys were in the rain.
Answer Auxiliary Verb
Description This verb is doing only the support action of mentioning the time of the event. The action is being determined by the main verb.
2. Did they see Rajesh?
Answer Auxiliary Verb
Description This verb is doing only the support action of mentioning the time of the event. The action is being determined by the main verb.
When main action words are mentioned in progressive forms (verb + “ing” form), they need auxiliary verbs. For example, in the sentence “I am talking”, the main verb is “talk”, which is in the verb + “ing” form. In these cases, auxiliary verbs are needed.
The structure is — Noun/pronoun + (corresponding auxiliary verb) + (main verb + “ing”)
The verb have, too, can be used both as an auxiliary and as a full verb. In sentences where there are no main verbs, “have-form” is used to mean a number of activities −
Important
When the have-form is not used as a main verb, then it is used to express actions that started in the past and have ended recently and people talking about its results or output. In such sentences, the have/has/had model will be used in the following model −
Have/has/had + verb in past participle form.
For Example
Some other cases where “have/has/had” is used −
Present Perfect Progressive − He has been playing football.
Past Perfect Progressive − He had been playing football.
Present/Past Perfect − The housekeeper has/had left the job.
Passive voices − The work has been assigned to him (we will discuss this later in Active/Passive voice)
In future time sentences
In future time sentences, the auxiliary verb “will” is used as an auxiliary verb when there is a main verb in the sentence. In case the sentence doesn’t have a main verb, the auxiliary verb “will be” is used.
I will go.
They will come.
They will not arrive on time.
Will they send me a bill?
She will be a certified dancer in June. (Here the word “will” is the auxiliary verb, and “be” is the main verb).
Important
“Will” is a pure auxiliary verb, i.e., you can’t use it as a main verb in any sentence. Sentences with only a subject and “will” don’t make any sense on their own.
For Example
The verb “do” exists in all sentences in either the same form or the “did” form depending upon the main verb, except the sentences where the “do” form is the main verb. In the “he/she/it” category of verbs, the “do” becomes “does” and the verb loses the ‘s’.
Important
“Do” is the verb that is used to deny the happening of the action that is represented by the main verb, even if the main verb is a “do” form.
For Example
The hidden ‘do’ will make the sentences −
I (do) wake up every day at 7.
I (do) swim for an hour daily.
He (does) brush his teeth daily. (the “brushes” becomes “brush” as the hidden “do” become “does” in the “he/she/it” category and nouns)
1. In present form
I/We/You/They- Do
He/She/It- Does
For Example
I do all my work myself
He does all his work himself.
2. In present form for negative sentences
I/We/You/They- Do not
He/She/It- Does not
For Example
I do not do all my work myself.
He does not do all his work himself.
3. In past form
I/We/You/They- Did not
He/She/It- Did not
For Example
I did not do all my work myself.
He did not do all his work himself.
4. In past form for negative sentences
I/We/You/They- Do not
He/She/It- Does not
For Example
I do not do all my work myself.
He does not do all his work himself.
Important
In question form also, “Do” form is the verb that is used to ask a question about the action that is represented by the main verb, even if the main verb is a “do” form.
Important
The negative form of “Do” is often used as a question to put emphasis on the speech, and also to show irritation.
