How to Use Modal Verbs in English

Modal verbs are auxiliary verbs that help express ability, permission, possibility, necessity, or obligation. These verbs are essential in English because they add nuance and depth to sentences,

allowing speakers to convey various meanings in different contexts.

Common modal verbs include:

Can, Could, May, Might, Must, Shall, Should, Will, Would

In this article, we will break down how to use modal verbs correctly with examples, and we’ll also provide practice exercises to help you master them.

Each modal verb has a unique function. Here’s a quick guide to understanding how each one is used:

Can – Ability or Permission

Use “can” to express ability or permission.

Example:

Ability: I can swim.

Permission: Can I borrow your pen?

Could – Past Ability or Polite Requests

Use “could” to express past ability or make polite requests.

Example:

Past Ability: When I was younger, I could run for miles.

Polite Request: Could you help me with my homework?

May – Permission or Possibility

Use “may” to ask for permission or express a possibility.

Example:

Permission: May I leave early today?

Possibility: It may rain later.

Might – Possibility (Less Certain)

Use “might” to express a less certain possibility than “may”.

Example:

She might come to the party if she finishes work early.

Must – Necessity or Obligation

Use “must” to express necessity or strong obligation.

Example:

You must wear a helmet when riding a bike.

Shall – Future or Suggestions

Use “shall” for future actions or to make suggestions (mainly in British English).

Example:

We shall meet at 3 PM.

Shall we go for a walk?

Should – Advice or Expectation

Use “should” for advice or to express what is expected.

Example:

You should eat more vegetables.

I should finish this report by tomorrow.

Will – Future Predictions or Willingness

Use “will” to express future predictions, or to show willingness or intentions.

Example:

I will call you tomorrow.

He will help you with your project.

Would – Polite Requests or Hypotheticals

Use “would” for polite requests or to discuss hypothetical situations.

Example:

Would you like some coffee?

If I were rich, I would travel the world.

Modal verbs do not change according to the subject, and they are followed by the base form of the main verb. Here’s the structure:

Subject + Modal Verb + Base Verb

Example Sentences:

I can speak French.

She must leave now.

They should study harder.

Many English learners make common mistakes with modal verbs. Here are some errors to watch out for:

Using the wrong modal verb:

Incorrect: I may to go to the party.

Correct: I may go to the party.

Using the wrong verb form after a modal verb:

Incorrect: She can to swim.

Correct: She can swim.

Confusing “must” and “have to”:

“Must” is stronger and more formal than “have to”.

Incorrect: I must to leave now.

Correct: I must leave now.
