Lesson 2: Action vs Auxiliary Verbs

In the English language, verbs play various roles to build meaningful sentences. Two key types of verbs are action verbs and auxiliary (also known as “helping”) verbs. Though both are essential in sentence construction, they serve distinct purposes.


Action verbs are the dynamic words that describe what the subject is doing. They are the main verbs that express physical or mental actions and are easily spotted in a sentence. For example, in the sentence “She runs every morning,” the word “runs” is an action verb that tells us what she is doing.

Here are some more examples of action verbs: jump, think, paint, laugh, solve.

ACTION VERBS


Auxiliary Verbs

Auxiliary verbs, on the other hand, do not stand alone. They accompany the main verb and provide additional meaning or tense to the verb phrase. They can indicate the possibility, obligation, or time of the action. Common auxiliary verbs include be, have, and do, as well as modal verbs like can, could, may, might, shall, should, will, and would.

For instance, in the sentence “She can run very fast,” “can” is an auxiliary verb that helps to express the ability of the subject in relation to the action verb “run.”


Here’s a breakdown of the roles these verbs play:

  • Action Verbs: Tell us the action happening in the sentence.
  • Auxiliary Verbs: Help modify, or change, the main action verb by adding grammatical nuances like tense, mood, voice, aspect, modality, or emphasis.

Understanding the difference between action and auxiliary verbs is crucial for creating clear and grammatically correct sentences. Action verbs bring the action to life, while auxiliary verbs fine-tune that action, defining when it happens and how it relates to other elements in the sentence.

Question 1

After reading the description of action verbs in the notes, can you identify the action verb in the following sentence and explain why it is classified as such? Sentence: “The children laughed loudly at the clown’s jokes."

Question 2

Based on the explanation of auxiliary verbs, choose the correct auxiliary verb to complete the sentence, and describe how it changes the meaning. Sentence: “She ___ (can/can’t) solved the difficult puzzle within minutes.”

Question 3

In the provided example sentence from the notes, “She can run very fast,” which word is the action verb and which is the auxiliary verb? Could you explain the different roles they play in this sentence?
