Modal verbs are helping verbs in English that we use to show things like ability, permission, possibility, necessity, and obligation. These verbs help us add more meaning to what we say. Unlike regular verbs, they don’t change their form based on tense or subject, which makes them unique.

Modal verbs like “can,” “may,” and “should” are some of the most common verbs in English. Learning how to use these words can really help you express your ideas clearly.

Modal verbs can be grouped based on their function. Each modal verb adds a specific meaning to a sentence. Let’s look at the different types of modal verbs, their uses, and some examples:

1. Ability Modals

Modal verbs like “can” and “could” are used to talk about ability.

Can: To show present ability.
- Example: Bilal can play the piano.
Could: To show past ability.
- Example: Amina could swim when she was five.

2. Permission Modals

Modal verbs like “can,” “could,” and “may” are used to ask for or give permission.

May: For formal permission.
- Example: May I borrow your book, Ali?
Can: For informal permission.
- Example: You can use my phone, Fatima.

3. Possibility Modals

Verbs like “may,” “might,” and “could” are used to show that something is possible but not certain.

Might: To show uncertainty or a weak possibility.
- Example: Ahmed might come to the party.
Could: To show a possibility.
- Example: They could be home by now.

4. Obligation and Necessity Modals

“Must” and “have to” are used to show obligation or necessity.

Must: For strong personal obligation.

5. Advice Modals

Modals like “should,” “ought to,” and “had better” are used to give advice or recommendations.

In English grammar, modal verbs are special helping verbs that don’t change their form based on the subject or tense. Unlike main verbs, modals are followed by the base form of another verb. They also don’t take an “-s” ending for the third person.

✅ Example: She can drive to work.

❌ Incorrect: She cans drive to work.

Modal Verbs in Questions

They are often used to ask questions, make requests, or ask about possibilities.

Can I help you with something?
Would you like some tea, Ali?
May I ask you a question?

Using modal verbs in questions makes your tone more polite and friendly. This is useful in both formal and informal situations.

Modal Verbs in Negations

Modal verbs can also be used in negative sentences to say that something is not allowed, possible, or a good idea. To make a negation, just add “not” after the modal verb.

He cannot (can’t) attend the meeting tomorrow.
You should not (shouldn’t) eat too much sugar, Ahmed.
They might not be able to join us today.

Modal Verbs in Reported Speech

When using modal verbs in reported speech, some of them change while others stay the same.

Direct Speech: “I will call you tomorrow,” Ahmed said.
Reported Speech: Ahmed said that he would call me the next day.

Some modals like must and should stay the same, while can changes to could, and will changes to would when reported.

Key Notes

They are always followed by the base form of another verb.
They do not take the “-s” ending for the third person.
Modal verbs express necessity, advice, possibility, and permission.
To make a modal negative, add “not” after the verb (e.g., cannot, should not).

Can vs Could

May vs Might

Will vs Would

Shall vs Should

Summary

Modal verbs are an important part of English grammar that help you add meaning to your sentences. They let you talk about ability, permission, possibility, necessity, and obligation, and they are often used in questions and negative sentences. By understanding them, you can express yourself more clearly in both formal and informal situations. They are simple to use since they don’t change with tense or subject, making them easy to learn but powerful for communication.
