Auxiliary verbs  also known as helping verbs, are the special words that make sentences clear and complete. These special words work alongside main action verbs to make sure our sentences are complete and clear.

They help us know exactly when something happens (like in the past, present, or future), how it’s happening, and sometimes even if it will happen at all.

Words like  is, am, are, have, do, and will play important roles, making our sentences easier to understand and more precise.

Without auxiliary verbs, sentences might sound confusing or incomplete.

Auxiliary verb examples, instead of saying “  I reading a book, ” we say, " I am reading a book ” That small helping word, “am,” turns the phrase into a clear question.

What is an Auxiliary Verb?

Auxiliary verb examples:

She is running.

  • Here, "is" is the auxiliary verb, and it helps form the present continuous tense with the main verb "running."

They have finished the project.

  • In this case, "have" is the auxiliary verb, working with the main verb "finished" to form the present perfect tense.

When to Use Auxiliary Verbs?

 Auxiliary verbs in english serve different purposes in sentences, helping us express time, ask questions, make negatives, or show possibility and ability. Here’s a closer look at each use with clear examples to help understand how auxiliary verbs work.

Showing Time (Tense)

Auxiliary verbs help indicate when something happened: in the past, present, or future. They make it easy to show if an action has already occurred, is happening now, or will happen later.

 Auxiliary verb examples sentences:

  • Past Tense: I was walking to the store. (The action of walking happened in the past.)
  • Present Tense: We are playing outside. (The action of playing is happening right now.)
  • Future Tense: She will be singing at the concert. (The action of singing will happen in the future.)

Asking Questions

Auxiliary verbs are essential in forming questions, especially when we want to know more about a particular action or event. These verbs often appear at the start of a question.

Examples:

  • Are you coming to the party? (The auxiliary verb ‘are’ helps form a question about a future action.)
  • Did you finish your homework? (The auxiliary verb ‘did’ helps ask about a completed action in the past.)
  • Have they arrived yet? (The auxiliary verb ‘have’ forms a question about a recent action.)

Auxiliary verbs in english make it easy to structure questions and clarify what information we are seeking.

Making Sentences Negative

 To make a sentence negative, we add not after the auxiliary verb. This is helpful when we want to say that something is not happening or is not true.

Auxiliary verb examples sentences::

  • She is not going to school. (The auxiliary verb ‘is’ plus ‘not’ shows that she isn’t attending school.)
  • They have not eaten breakfast yet. (The auxiliary verb ‘have’ and ‘not’ indicate that breakfast hasn’t happened.)
  • I cannot swim. (The modal auxiliary ‘cannot’ shows inability or lack of permission.)

Adding ‘not’ after auxiliary verbs clearly expresses what is not happening or isn’t allowed.

Showing Possibility or Ability (with Modal Verbs)

Modal auxiliary verbs, such as can, must, may, and should, show what is possible, allowed, required, or advised. These verbs help us express someone’s capability or the likelihood of something happening.

  Examples:

  • I can swim. (The modal auxiliary ‘can’ shows ability – that the person knows how to swim.)
  • You must finish your homework. (The modal auxiliary ‘must’ shows necessity or obligation.)
  • She may join us later. (The modal auxiliary ‘may’ shows that joining is possible, but not certain.)
  • You should try this recipe. (The modal auxiliary ‘should’ suggests advice.)

Common Auxiliary Verbs with Examples

 Auxiliary verbs add specific meanings to sentences, showing when actions happen or describing abilities and possibilities. Here’s a look at Auxiliary verb list with examples to illustrate their use:
