Elementary Grammar A2
In this article, Elementary Grammar A2 learners study must and have to.
You will learn how must and have to express strong obligation, rules, and necessity.
The key question is: Is the obligation personal, official, external, or logical?
The main rule to remember is: Use modal verb plus the base verb without to, except for semi-modals such as ought to and have to.
You will study must, have to, must not, and do not have to in realistic sentences.
By the end, you should be able to separate obligation from lack of necessity.
Modal verbs add meaning to another verb. They express ability, possibility, permission, advice, obligation, deduction, willingness, and politeness.
Must and Have To Explained looks specifically at must and have to. At this level, the goal is to connect basic grammar with longer speaking and writing tasks.
As you read, keep one question in mind: Is the obligation personal, official, external, or logical? This question will help you connect the rule to meaning instead of memorizing the form alone.
You will see must, have to, must not, and do not have to in realistic sentences, then practice the topic through corrections, short tasks, and a final review.
This section breaks must and have to into practical rules. Read each rule, study the examples, and notice how the form supports the meaning.
Use can, could, may, and might to talk about ability, possibility, and uncertainty.
Use should, must, have to, and ought to for advice, rules, and necessity.
Use must, might, could, and can't to guess from evidence.
