Modal verbs: must
The modal verb 'må' expresses necessity and obligation in Norwegian.

Pay attention to the highlighted parts. What do they have in common?
The modal verb må expresses necessity or obligation. Always followed by infinitive without 'å'.
Key distinction:
- Må ikke = must NOT (prohibition): 'Du må ikke røyke her.'
- Trenger ikke = don't have to (not required): 'Du trenger ikke betale.'
🇬🇧 'Må ikke' ≠ 'don't have to' — it means MUST NOT. Use 'trenger ikke' for 'don't have to'.
