IELTS Grammar — How to Use Modal Verbs (Can, Should, Must, Might)

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)
• "It must be true" (deduction/logical conclusion)

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)

• "It may rain tomorrow" (possibility — 50%)
• "It might rain tomorrow" (possibility — 30%)
• "You may leave now" (permission)

Would (Polite/W Hypothetical)

• "Would you help me?" (polite request)
• "I would travel if I had money" (hypothetical)
• "I would like to apply" (polite expression)

Common IELTS Mistakes

• ❌ "You should to study" → ✅ "You should study" (no "to" after modals)
• ❌ "I can to speak English" → ✅ "I can speak English"
• ❌ "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)
