Auxiliary Verb Definition
Auxiliary Verbs: Auxiliary verbs, often referred to as helper verbs or aiding verbs, support the main verb in a phrase to convey difficult grammatical ideas, such as modalities or time aspects. For instance, the auxiliary verb helps the main verb to finish the sentence, “I have finished the report.”
Because auxiliary verbs might be challenging, we’ve provided all the information you need below. We give concrete examples of typical auxiliary verbs and describe when and how to use them.
What is an Auxiliary Verb?
Auxiliary verbs provide a supporting role behind the primary verb in the main sentence. They are mostly employed to construct intricate grammatical tenses, like as the perfect and continuous tenses, which depict several facets of time or the duration of an action.
For examples:
- I like to study. (Simple Present Tense).
- I am going to play. (Present Continuous tense).
In the above examples, first sentence doesn’t require an auxiliary verb because in simple/indefinite tense, auxiliary verb is not used. However, in second sentence ‘am’ is used which is an auxiliary verb because other than simple tenses all tenses need auxiliary verb to support the main verb.
Auxiliary Verb Definition
According to the Oxford Learners’ Dictionary, an auxiliary verb is “a verb such as be, do, and have used with main verbs to demonstrate tense, etc. and to construct questions, and negatives.”
Auxiliary verbs are “the verbs ‘be’, ‘do’, and ‘have’ in English, when they are employed with another verb to construct tenses, questions, question tags, and the passive,” according to the Macmillan Dictionary. Am, are, do, and has been are all auxiliaries in the sentences “I’m listening,” “Are you working,” “You don’t like her, do you?” and “The bill has been paid,” for instance.
An auxiliary verb is defined as “a verb that is employed with another verb to generate tenses, negatives, and questions” by the Cambridge Dictionary. The auxiliary verbs in English are “be,””have”.

How to identify Auxiliary verb?
You are probably aware that every sentence contains a verb of some kind. Verbs can be divided into two categories. Action verbs are used to describe tasks that can be completed, while linking verbs are used to explain circumstances. The three primary auxiliary verbs—do, be, and have—can be accompanied by action verbs or connecting verbs.
Sometimes events or circumstances only happen once before ending. In situations like this, several verbs that are often used as auxiliary verbs are switched out for action or linking verbs. The word “is” can be seen in this illustration. This is one of the most popular auxiliary verbs, however since it stands alone in this sentence, it is not doing its intended job.
John slammed the door on Tom’s hand. He is in the pain.
In this line, “is” serves as a connecting verb. It is not an auxiliary verb because it is a stand alone verb.
Other times, a situation, activity, or condition is ongoing, predictable, or connected to another occurrence or series of events. In certain circumstances, phrases with auxiliary verbs are utilised instead of single-word verbs like is because they better capture what transpired. These could contain anything between two and four words.
A primary verb, usually referred to as a base verb, describes the nature of the activity or condition that is occurring. Auxiliary or assisting verbs are used in conjunction with the primary verb to express additional information that gives the reader more detail about the action that is taking place.
