Auxiliary and modal verbs play a crucial role in English grammar, yet many learners struggle to use them correctly. Errors in their usage can alter the meaning of sentences, leading to confusion. This article will highlight common mistakes and provide practical tips to help you master these verbs with confidence.
Understanding Auxiliary and Modal Verbs
Auxiliary verbs (helping verbs) include be, have, and do, which assist the main verb in forming different tenses, voices, and questions. Modal verbs (can, could, may, might, must, shall, should, will, would) express ability, possibility, necessity, and permission.
To improve your English, it’s essential to recognize frequent mistakes and learn how to correct them.
Common Mistakes with Auxiliary Verbs
1. Incorrect Subject-Verb Agreement
✖ She have finished her homework.
✔ She has finished her homework.
Many learners forget to match the auxiliary verb with the subject correctly. “Has” should be used with singular subjects, while “have” is for plural subjects and “I/you.”

2. Overusing “Do” in Affirmative Sentences
✖ I do like pizza.
✔ I like pizza.
“Do” is usually used for emphasis or in questions/negations. Avoid unnecessary use in affirmative statements.
3. Forgetting “Do” in Questions and Negations
✖ You like coffee?
✔ Do you like coffee?
In questions, “do/does/did” is essential when no other auxiliary verb is present.
Common Mistakes with Modal Verbs
1. Using “To” with Certain Modals
✖ She must to go now.
✔ She must go now.
Modal verbs are followed directly by the base form of the verb without “to.”
2. Misplacing Modals in Questions
✖ Where I can find the book?
✔ Where can I find the book?
The modal should always come before the subject in a question.
3. Mixing Up “Can” and “Could” for Ability
✖ I could swim well now.
✔ I can swim well now.
“Can” is for present ability, while “could” refers to past ability.
How to Avoid These Mistakes
✔ Study sentence structures with auxiliary and modal verbs. ✔ Practice using correct forms through exercises. ✔ Read English books and articles to see correct usage in context. ✔ Listen to native speakers and note how they use these verbs. ✔ Keep a grammar reference handy for quick checks.
Conclusion
Understanding auxiliary and modal verbs is crucial for mastering English. By avoiding these common mistakes and practicing consistently, you can enhance your grammar skills and communicate more effectively.
