Okay, in this lesson, we're going to continue the topic of less and fall, which is the verb Haft and listen for.

We learned how to congregate, have to correctly in different tenses in this lesson will deal with the common mistake off treating have to and must as synonyms which is sometimes okay, but not always.

So let's look at when you can use them a synonyms and when you can't his it was up.

English errors Less than five must or have to.

Let's start with this question.

Doom.

Us.

Don't have to express the same idea.

What do you think?

Well, not exactly.

They don't express the same idea, but similar ideas.

One expresses an external obligation, a rule.

The other one expresses a strong necessity felt by the speaker.

Do you remember which one is which?

Which one expresses an external obligation?

Right?

It's have to.

For example, according to my contract, I have to be at work by 8 a.m. That means that a strong necessity is expressed by must.

To avoid the rush hour traffic, I must leave home by 7 a.m. But this distinction is vague and often ignored, so you can use the two interchangeably you can also use need to as an alternative to pose.

So that brings us to the next question, which is do muscles and don't have to also expressed similar ideas.

What's your answer?

Well, here the answer is no.

They expressed different ideas.

Want removes an obligation or necessity.

The other one expresses at Prohibition An obligation or a necessity not to do something.

Do you remember which one is which?

Which one removes an obligation or a necessity?

Correct.

Don't have to.

Oh, don't need to.

For example, I'm on a flexi time contract.

I don't need to.

Where?

I don't have to be at work by 8 a.m. We have removed the application here.

Oh, I walk to work.

I don't have to.

I don't need to leave home by seven.

To avoid the Russia here we have removed the necessary.

So that means that in order to express an obligation or a necessity not to do something we use Mustn't.

For example, my contract says that I mustn't arrive any later than 8 a.m. Huh?

To avoid the rush hour.

I mustn't leave home any later than seven.

Right?

And the final question I'd like you to think about his doom.

Us don't have to follow the same grammar rules.

What do you think?

Well, the answer is again.

No, As you will remember from my easy for lesson one off them is a motive.

Herb and the other one is an ordinary va.

Do you remember which one isn't ordinary verb correct?

Have to is an ordinary verb and, as an ordinary verb have to and don't have to can be used in any tense or structure, for example, had to We'll have to have had to should have to after a model Bob all in the negative.

Didn't have to.

Who won't have to haven't had to.

Shouldn't have to.

Now need to is also an ordinary verb, so you can use it in exactly the same way as have to just a little note here that you may see need without two used as a motive up.

But that's very rare.

I'd recommend you always use meat, so if have to is the ordinary of up.

That means that must is the motive up.

Now, as a motive, Herb must has only wonderful, and it can only express a necessity in the present or future to express a necessity in other tenses we use have to or need to.

So we can say every day I must Oh, tomorrow I must.

But yesterday you have to switch tohave to yesterday I had to or I need it too.

Recently, I've had to or I've needed to.

And the same goes for muscles.

It can only express prohibits shin in the present or future to express prohibition in other tenses.

Use the verb allow in the negative.

So if we have in the present today, we mustn't interrupt the speaker.

If you want to speak about yesterday, we can use the verb allow.

Yesterday we weren't allowed to interrupt the speaker and this would indicate an external obligation.

A rule?

Oh, yesterday I didn't allow myself to interrupt the speaker.

This would be a self imposed internal prohibition.

Okay, let's do a quick summary before we do the very important exercises.

So first of all, although mustard have to express slightly different ideas, they're interchangeable.

And you can use need to as well.

So we can say she's ill.

So she must all she has to Oh, she needs to rest a necessity or an obligation to do something.

The difference is vague and not very important, but mustn't and don't have to or don't need to express completely different ideas.

For example, she's in, so she mustn't work here.

It's a necessity or an obligation not to do something.

Compare that with she is ill, but she doesn't have to or she doesn't need to see a doctor here.

There is no necessity or obligation to see the doctor.

And finally must is a mode over and have to is an ordinary verb.

Their grammar rules are very different.

If you're unsure about these, please watch my easy for lesson.

Okay, It's time for exercises.

I'd like you to choose between must and half to to express the same idea and make sure you use the correct form, positive or negative.

And the correct tents, for example, say it will be an obligation for us to pay the bill.

We will have to pay the bill on obligation in the future.

But we can use must as well.

Second example say it is necessary for us not to lose hope.

We lose hope.

We mustn't lose hope and necessity not to do something in the present.

Okay.

Your time number one say it isn't an obligation for us to vote.

We vote.

We don't have to vote.

Removing an obligation in the present.

Okay.

Number two say it was necessary for him to quit his job.

Hey, quit his job.

He had to quit his job and necessity in the past.

We have to use the verb have to because must doesn't have a past four.

Okay.

Number three say it is necessary for her to leave now.

She leave now.

She must leave now.

Necessity in the present.

But has two is also possible.

Number four say it will be necessary for us not to get back late tonight.

We get back late tonight.

We mustn't get back late tonight.

A necessity not to do something in the future.

Number five say it won't be an obligation for him to resign.

King resigned.

He won't have to resign removing an application in the future.

All right.

Number six say it will be an obligation for everyone to pay this tax next year.

Everyone pay this tax next year.

Everyone will have to pay this tax next year an obligation in the future, you can use must as well.

Number seven Say it wasn't necessary for the visitors to Q.

The visitors.

Q.

The visitors didn't have to queue removing and necessity or an application in the past.

Number eight say it is necessary for him not to get stressed.

Hey, get stressed.

He mustn't get stressed a necessity not to do something in the present.

Number nine say it may be necessary for the seller to lower the price.

The cellar may lower the price.

The seller may have to lower the price.

Although I have said necessary because we have the motive up May we cannot put another motive, Herb after it.

So we cannot use Must it's have to the seller may have to lower the price.

Okay, on finally say it hasn't been necessary for them to rush.

They rush.

They haven't had to rush removing the necessity in the present.

Perfect tense.

Okay, that's the end of Lesson five.

If this is the first time that you have fully understood the differences between must and have to especially the difference between mustn't and don't have to please watch the listen again and repeat the exercises until you can use the two forms in the right place without hesitation.
