Grade 7 Grammar Lesson 10 Modals

We use must to express necessity or obligation.

 Must is often used when the obligation comes from the speaker.

When the obligation comes from somewhere else, we often use ‘have to’ instead of must.

Must is generally used for the present and the future while have to is used in all tenses.

Must doesn’t have a past form, so we use had to for a past obligation.
