Use the correct modal verb

Key Notes:

Modal verbs are special auxiliary verbs that are used to express ability, permission, necessity, possibility, or obligation. They add meaning to the main verb in a sentence.


  • Can / Could – Ability or possibility.
    • Example: I can swim. / I could go to the party.
  • May / Might – Permission or possibility.
    • Example: May I use your phone? / It might rain tomorrow.
  • Will / Would – Future intention or polite requests.
    • Example: I will call you later. / Would you like some help?
  • Shall / Should – Suggestions or advice.
    • Example: Shall we go for a walk? / You should study more.
  • Must – Necessity or strong obligation.
    • Example: You must wear a helmet.
  • Ought to – A suggestion or advice (similar to “should”).
    • Example: You ought to read more books.

  • Modal verbs are followed by the base form of the main verb (without “to”).
    • Example: She can speak three languages. (NOT: She can speaks)
  • They do not change according to the subject.
    • Example: I can help you. / She can help you. (Same form “can” for all subjects)

  • Can: “She can play the piano.”
  • Could: “I could finish the work by tomorrow.”
  • May: “You may leave early today.”
  • Might: “They might come to the party.”
  • Will: “I will visit my grandmother.”
  • Shall: “We shall meet after school.”
  • Should: “You should eat healthy food.”
  • Must: “You must wear a seatbelt.”
  • Ought to: “You ought to help your parents.”

  • Ability: Use can (present) or could (past).
    • Example: I can solve this math problem.
  • Permission: Use may (formal) or can (informal).
    • Example: May I go to the bathroom?
  • Possibility: Use might or may.
    • Example: It might snow tomorrow.
  • Obligation: Use must or have to.
    • Example: I must finish my homework before I go out.
