Using 'Should', 'Ought To', and 'Must' for Advice helps you express varying levels of advice and obligation. These modals allow you to convey how strongly you recommend or require an action to be taken. In this lesson, you will learn how to choose the right modal for your intended message.
Examples
Example 1

How It Works
Meaning
'Should', 'ought to', and 'must' are modal verbs used to give advice or express obligation. They help convey the strength of your recommendation or requirement. 'Should' and 'ought to' suggest advice or mild obligation, while 'must' indicates a strong necessity or obligation.
Formation: modal + base verb (e.g., should go, must see).
At the B2 level, understanding the nuances between these modals is crucial for effective communication.
Use it when
- Giving advice or recommendations (e.g., "You should see a doctor.")
- Expressing mild obligation or expectation (e.g., "You ought to finish your homework.")
- Indicating strong necessity or rules (e.g., "You must wear a seatbelt.")
- Writing formal letters or reports where recommendations are needed.
- In spoken responses during exams or interviews to suggest actions.
