What Are Modals?

Modals are verbs that give additional meaning to the main verb in a sentence. They help express different moods or conditions. Common modals include:

  • Can – expresses ability or permission.
  • Could – expresses past ability or polite permission.
  • May – expresses permission or possibility.
  • Might – expresses possibility or suggestion.
  • Must – expresses necessity or strong recommendation.
  • Shall – expresses future intention or suggestion.
  • Should – expresses advice, recommendation, or obligation.
  • Will – expresses future intention or strong likelihood.
  • Would – expresses polite requests or hypothetical situations.
  • Ought to – expresses moral obligation or duty.

Types of Modals

1. Modals of Ability

Can is used to express ability in the present.

Example: She can speak three languages fluently.

Could expresses ability in the past.

Example: He could swim when he was five years old.

2. Modals of Permission

Can is used to ask or grant permission.

Example: Can I go to the restroom?

May is a more formal way to ask for permission.

Example: May I leave early today?

3. Modals of Obligation

Must is used to express necessity or a strong recommendation.

Example: You must wear a seatbelt while driving.

Should is used to give advice or express mild obligation.

Example: You should finish your homework before going out.

4. Modals of Possibility

May expresses a possibility.

Example: It may rain later in the day.

Might also expresses a possibility but with less certainty than “may.”

Example: She might attend the party tomorrow.

5. Modals of Advice

Should is used to offer advice.

Example: You should eat more vegetables for better health.

Ought to is similar to “should” but slightly more formal.

Example: You ought to apologize for your behavior.

6. Modals of Future

Will expresses future intention or certainty.

Example: I will help you with your project tomorrow.

Shall is more commonly used with “I” and “We” for making suggestions or offering.

Example: Shall we go to the movies tonight?

How to Use Modals Correctly

To use modals correctly in sentences, it’s important to understand their functions and contexts. For instance:

  • Can is often used for ability or permission in present contexts.
  • Must is used for strong obligations or necessary actions.
  • May and might are more commonly used for expressing possibility or asking for permission.

Remember, modals do not change according to the subject; for example, “She can” and “They can” both use “can” without any changes.

Common Mistakes with Modals

1. Incorrect Verb Forms After Modals

After modals, the main verb remains in its base form (without “to”). For example, You should go (not You should to go).

2. Confusing Modals of Permission and Possibility

Words like can, may, and might can express both permission and possibility. It’s important to choose the right context.

Can I use your phone? (permission)

It may rain tomorrow. (possibility)

3. Overuse of “Must”

While must expresses strong obligation, it can sound too forceful in informal situations. Should or ought to are better for expressing mild advice or suggestions.
