What Are Modal Verbs?

Modal verbs are auxiliary (helping) verbs that express the attitude of the speaker toward the action of the main verb. Unlike regular verbs, they don’t change according to the subject, and they are always followed by the base form of a main verb.

Examples of Modal Verbs:

  • Can
  • Could
  • May
  • Might
  • Shall
  • Should
  • Will
  • Would
  • Must
  • Ought to
  • Need

The Different Types of Modal Verbs

Each modal verb serves a specific purpose. Let’s explore the various ways these verbs are used in English.

1. Ability

“Can” and “could” are used to talk about the ability to do something.

  • Can (present ability):
    I can swim.
  • Could (past ability or polite request):
    When I was younger, I could run very fast.

2. Permission

“Can,” “could,” “may,” and “might” are used to ask for or give permission.

  • Can (informal permission):
    Can I go to the bathroom?
  • May (more formal permission):
    May I leave early today?
  • Might (less certain permission):
    You might be able to join the meeting later.

3. Possibility

“May,” “might,” and “could” are used to talk about possibility.

  • May (higher probability):
    It may rain tomorrow.
  • Might (lower probability):
    She might go to the party later.
  • Could (possible under certain conditions):
    That could be the answer to your question.

  • Must (strong obligation):
    You must wear a helmet while riding a bike.
  • Have to (general necessity):
    I have to finish this report by tomorrow.
  • Should (advice or mild obligation):
    You should take an umbrella with you.

5. Advice

“Should” and “ought to” are used to give advice.

  • Should:
    You should study for the test.
  • Ought to (more formal):
    You ought to apologize for being late.

6. Future Predictions

“Will” and “shall” are used to talk about future events or predictions.

  • Will (future predictions or promises):
    I will call you later.
  • Shall (often used in formal or legal contexts):
    I shall return the book by next week.

How Modal Verbs are Tested in the International English Test (IET)
