Modal Verbs for Advice and Rules: Should, Must & Have To

Modal verbs help us talk about rules, advice, and obligations. Three very common modal verbs at B1 level are should, must, and have to. They are especially useful when talking about daily life in Ireland, school rules, and social situations.

Using “Should” for Advice

We use should to give advice or say what we think is a good idea.

Exemples :

• Vous should bring a jacket in Ireland.
• Vous should practise English every day.
• Vous shouldn’t be late for class.

“Should” is not strong. It is friendly and polite.

Using “Must” for Strong Rules

We use must when a rule is very important or comes from the speaker.

Exemples :

• Vous must wear a seatbelt.
• Vous must arrive on time for the exam.
• Vous mustn’t smoke inside buildings.

“Must” sounds strong and serious.

Using “Have To” for External Rules

We use have to when the rule comes from another person, system, or law.

Exemples :

• I have to pay my rent this week.
• Les étudiants have to attend classes regularly.
• Nous don’t have to work on public holidays.

“Have to” is very common in spoken English.

Often, must et have to have similar meanings, but:

• must = personal or strong rule

Exemples :

• I must study tonight. (my decision)
