Grammar: Modal Verbs (Can, Could, May, Might, Must, Should)
Modal verbs are auxiliary verbs that express possibility, necessity, permission, ability, and obligation. This is a fundamental grammar topic for the Baccalaureate.
List of Modal Verbs
| Modal | Use | Example |
|---|---|---|
| Can | Ability, permission, possibility | I can swim. You can go now. |
| Could | Past ability, polite request, possibility | I could run fast. Could you help me? |
| May | Permission, formal possibility | May I come in? It may rain. |
| Might | Less certain possibility | It might snow tomorrow. |
| Must | Strong obligation, necessity | You must wear a seatbelt. |
| Should | Advice, recommendation | You should study more. |
| Will | Future prediction, promise | It will be sunny tomorrow. |
| Would | Polite request, conditional | Would you like some tea? |
Key Rules
- Modal verbs don’t change for third person (he can, NOT he cans).
- They are followed by the base form of the verb (can go, must work).
- To form negatives, add “not” after the modal (cannot / can’t, must not / mustn’t).
- To form questions, invert the modal and subject (Can you help? Should I go?).
- They don’t have infinitives or past participles.
Degree of Certainty
- 100%: Must (certain), Will (definite)
- 50-70%: May, Might, Could (possible)
- 0%: Cannot / Can’t (impossible)
Exercises
- Complete with the correct modal: “You ___ stop at a red light. ___ I open the window? It’s cold, it ___ snow. You ___ try this dish, it’s delicious.”
- Rewrite using a modal: “It is necessary to study. (must) It is possible that he is late. (might) I advise you to see a doctor. (should)”
