Explanation
Must shows duty and rules: “We must do our homework.” Mustn’t (= must not) shows that something is forbidden: “We mustn’t run in the corridor.” After must the verb is in the base form and never takes -s: He must go. The form is the same for all persons: I, you, he, we, they must. School rules: “Pupils must come on time. Pupils mustn’t use phones in the lesson.” A dangerous thing: “We mustn’t play with matches!”
Worked examples
At school we must be on time. We must listen to the teacher. We mustn’t shout in the lesson. We mustn’t throw rubbish on the floor.
Dad said: You must feed the cat every morning. You mustn’t eat sweets before dinner.
