What Are Modal Verbs in English Grammar?
Modal verbs in English grammar are special auxiliary verbs. They express ideas such as ability, advice, permission, possibility, or necessity. Using modal verbs makes your writing and speech more precise and expressive. At Vedantu, we explain modal verbs in a way that helps students use them confidently for exams and daily English.
Types of Modal Verbs and Their Functions
There are main modal verbs and semi-modals. The most common are can, could, may, might, must, shall, should, will, and would. Semi-modals include need, ought to, and have to. Each type expresses a different shade of meaning, such as asking for permission or giving strong advice.
- "Can" and "could" show ability or request.
- "May" and "might" talk about possibility or permission.
- "Must" and "need" show necessity.
- "Should" and "ought to" give advice or recommendation.
- "Will" and "would" refer to future actions or polite offers.
How to Use Modal Verbs in Sentences
Modal verbs always come before the base form of the main verb and do not change for person or number. For example, “She can dance” and “They can dance” both use “can.” Use modals for questions by moving the modal before the subject: “Can you swim?” Negatives are formed by adding “not”: “He should not be late.”
- Use the same form of the modal verb for all subjects.
- Do not add "to" after modal verbs (except semi-modals).
- Make negatives by adding “not” after the modal: You must not shout.
Modal Verbs: Quick Practice Tasks
- Underline the modal verb in these sentences: “She must leave early.” “We could meet after class.”
- Change “He will go to school” to show less certainty: “He might go to school.”
- Write three sentences using “can”, “must”, and “should.”
Common Mistakes with Modal Verbs
- Using incorrect verb form: Don’t say “She can to swim.” Say “She can swim.”
- Confusing advice and obligation: “Must” is stronger than “should.”
- Adding “s” or “ed” to modal verbs: Modals do not change form.
- Forgetting “not” for negatives: Always use “cannot” or “should not.”

FAQs on Modal Verbs: Definition, Types, and Examples
1. What are modal verbs in English grammar?
Modal verbs are auxiliary verbs that express possibility, permission, ability, necessity, or obligation. Common examples include can, could, may, might, must, should, will, and would. They modify the meaning of the main verb in a sentence.
2. How do you use modal verbs in sentences?
Modal verbs always precede the main verb (without 'to'). For example: She can sing. He should study. They must leave. They express the speaker's attitude towards the action.
3. What is the difference between modal verbs and auxiliary verbs?
All modal verbs are auxiliary verbs (helping verbs), but not all auxiliary verbs are modal verbs. Primary auxiliaries (be, have, do) help form tenses; modal verbs express modality (possibility, obligation, etc.).
4. What are the common modal verbs in English?
The most common modal verbs are: can, could, may, might, must, should, will, would. Others, such as shall and ought to, are less frequently used in modern English.
5. How are modal verbs used in questions?
To form a question, the modal verb comes before the subject. For example: Can you help me? Should we go? Will it rain?
6. How are modal verbs used in negative sentences?
To make a negative sentence, add 'not' after the modal verb (often contracted). For example: She cannot (can't) swim. He should not (shouldn't) go. They will not (won't) come.
7. Do modal verbs change their form for different subjects?
No, modal verbs do not change their form based on the subject (I, you, he, she, it, we, they). They remain the same for all subjects. This is called invariance.
8. What are some common mistakes students make with modal verbs?
Common mistakes include: using the infinitive 'to' after a modal verb; confusing modals of permission (can, may) with modals of obligation (must, should); incorrect usage of past modal forms.
9. Can modal verbs be used to express different degrees of certainty?
Yes, different modal verbs express varying degrees of certainty. For example, might suggests a lower probability than will. Must indicates a strong inference, while should suggests a milder possibility or advice.
10. How are modal verbs used in the past tense?
Some modal verbs have past tense equivalents (could for can, would for will, etc.). Others use the perfect infinitive (have + past participle) to express past time, e.g., I should have studied harder.
11. What are semi-modal verbs?
Semi-modal verbs are verbs that function similarly to modal verbs but have slightly different grammatical behavior. Common examples include have to, need to, ought to, used to. They express obligation or habit.
12. How can I practice using modal verbs?
Practice using modal verbs through exercises, quizzes, and real-life sentence construction. Focus on understanding the nuances of each modal verb and its specific use in different contexts. Working with example sentences is also beneficial.
