Modal Verbs — Advice, Possibility, Obligation

B1 Intermediate
⏱ 5 minutes
Grammar
📖 From My Life

When I started learning French at the age of 35 in La Réunion, my tutor said, “You should practise every day. You must speak even if you make mistakes. You can do this — many adults learn French to C1.” She was right. Modals are how we express advice, possibility, and obligation in English too.

🎯 Language Focus

Obligation/Rule must / have to → “You must complete the form.”
Advice should / ought to → “You should practise daily.”
Possibility might / could / may → “It might be difficult at first.”
Ability can → “I can speak four languages.”

✏️ Quick Practice — Try It!

1. Obligation or advice? “You must wear a seatbelt.”

Obligation/Rule ✓ — it’s the law.
2. Fill: “You ___ try the local food — it’s amazing!” (advice)

should ✓.
3. Fill: “She ___ be at home — I’m not sure.” (possibility)

might / could / may ✓.
4. Write a sentence: give advice to a new English learner.

e.g. “You should speak English every day, even with yourself.” ✓.

💡 Your 5-Minute Takeaway

Must = obligation (rule/law). Should = advice (my opinion). Might = possibility (not sure). These three cover 90% of modal situations at B1.
