This video is about the modal verb "have to." This modal verb is mostly used for obligations but not only. In this lesson, I will use obligation for amE and brE. It is an impersonal obligation, so somebody or an institution obliges a person to do something following a rule or law. The lesson will give you the different types of sentences to use it with. This lesson is for elementary students who wish to study or review English grammar and for students who reached an advanced level but who wish to brush up on some grammar rules.

Hello everyone, this is Marc again. How are you today? Today we're going to look at
have to. I have a sentence for you. You have to be quiet during a lecture at
university. You have to be quiet during a lecture at university. So we use the
modal verb have to for a strong obligation. This obligation has to be
imposed by a rule or by the law, okay, is in other words an impersonal obligation.
Okay, somebody else tells you to do something. We use it a lot in American
English, okay, instead of must. Must is disappearing and in British English they
even use you have got to. Have got to. Okay, it's the same. Pay attention to the
tense you want to use have to because yes have to can be used in the past, in
the present and in the future. So I can say you had to learn English when you
were younger, okay, you have to learn English now and you will have to learn
English when you're an adult, okay. Remember though that you have to pay
attention to the auxiliary because have to works not as a full verb but as a
verb, as a main verb, okay. So let's look at my introductory example. I said you
have to be quiet during a lecture at university, okay. Somebody tells you you
need to be quiet during a lecture at university, okay. So now let's look at the
different types of formulas. We have for a positive sentence, the subject, then we
need have to, okay, then we need the verb in the infinitive because there is to,
okay, and then the object. Pay close attention that sometimes we need the
auxiliary, for example, in a future tense sentence. You need the auxiliary before
have to, okay. So let's take a look at an example now. You will have to learn
English, okay, you will have to learn English but if use the same sentence in
the present, obviously, we don't write the auxiliary. So I say you have to learn
English, okay. This is for a positive sentence. So now let's look at the
negative sentence. We have the subject first, then the auxiliary plus not, then
have to, and then the verb infinitive, and the object at the end. So let's take a
look at the same example that I gave you before. You will not, you won't have to
learn English. You won't have to learn English in the future, okay. And now let's
look at an interrogative sentence. An interrogative sentence goes, obviously,
with the WH question word at the beginning. If there is, then we need the
auxiliary, then we need the subject, then have to, then the verb, okay, infinitive, and
then maybe if there is an object. What will you have to do when you move to
Canada? What will you have to do when you move to Canada? Okay, this could be an
example. Okay, let's recap now. So have to is used to express a strong
obligation based on a law or rule imposed by somebody or an institution. So
it's an impersonal obligation. It's an impersonal action, okay. So you have to
pay attention to the tenses that you use have to with because it may change the
auxiliary, okay, that you need to use. I said also that in British English they
use also have got to which is the same thing. In American English it replaced
must, okay, so instead of must we use have to for everything, okay, and we
conjugate have to according to the tense we use, okay, so pay attention to that.
So now I have a question for you. What do you have to do to be admitted to
university in your country? What do you have to do to be admitted to university
in your country? Okay, write your answer under this video. If you have questions
or requests you may write them also under this video. I hope you enjoyed the
lesson and I see you next time. Take care. Bye-bye.
