IELTS Grammar: Modal Verbs Can, Should, Must

What Are Modal Verbs?

Modal verbs express ability, necessity, possibility, or advice. They're essential for both IELTS Writing and Speaking.

Main modals: can, could, may, might, must, shall, should, will, would, ought to

Modal Verbs and Their Meanings

Can / Could (Ability/Possibility)

• "I can speak English" (present ability)
• "I could speak English when I was young" (past ability)
• "It could rain tomorrow" (possibility)

Must / Have to (Necessity/Obligation)

• "You must follow the rules" (strong obligation)
• "I have to wake up early" (external obligation)

Should / Ought to (Advice)

• "You should study every day" (advice)
• "You ought to respect your elders" (advice, slightly more formal)
• "The government should invest in education" (recommendation)

May / Might (Possibility)

• ❌ "Must I go?" → ✅ "Do I have to go?" (for questions about obligation)
• ❌ "He must not at home" → ✅ "He must not be at home" (use base verb)
