  • Hi, friends, thanks for clicking and welcome back to a grammar lesson. I am Niharika and

  • In today's lesson, we are gonna look at the difference between have to, supposed to and

  • ought to. We are gonna understand how to use these words in your sentences in English.

  • Also, before we go ahead and look at the explanation, well make a note that these words are modals

  • and are always followed by verbs. Okay, so make sure, you make a note of this and now

  • let's understand the difference. The first thing that we are going to look at is, have

  • to. Now when do we use have to in English? And what exactly it means? Now have to, can

  • be used, the way, we use the word, must. It is used in a situation where you have no choice.

  • Yeah, there are times when we have or when we can choose, what we want to do. But when

  • we end up using, have to or we end up using the word, must in our sentences, it means

  • that it is used for a situation, where we have no choice and we have to do that thing.

  • Yes, it is used for a situation, when you have no choice. Now to understand this better,

  • let's have a look at some examples on the board. The first one is, I have to learn English.

  • So here, probably, you're using this, have to or you can also say, I must learn English,

  • it's because you don't have a choice. Maybe you have moved to an English speaking country

  • and you're not able to live there, without speaking English. So, you have no choice,

  • if you want to live a comfortable life, in an English speaking country, it's important

  • for you to learn English. Okay, so that's exactly why you will say, that I have to learn

  • English because you have no choice. Let's have a look at another example, using the

  • word, have to. I have to submit the reports tomorrow. Okay, now you need to understand,

  • that again, we can either use, have to or must like, I must submit the reports tomorrow

  • or else there will be consequences. So you have no choice, okay it's like the deadline,

  • you have to do it, okay or else your boss is really going to be mad at you. So you are

  • saying that I have to submit the reports tomorrow. The last example for you is, I have to pay

  • my taxes. Oh yes, you can't skip, paying off your taxes. It is important for you to pay

  • your taxes and you have no choice. Yes, if you again want to live a comfortable life

  • in a country, it's important for you, to pay your taxes. You cannot back off. So you no

  • choice and you have to pay your taxes or you must pay your taxes. So, that's how, you will

  • use have to or must in English, okay.

  • Now, let's move on and understand, when do we use supposed to? Now supposed to, is used

  • in English in a situation where there's an obligation

  • or it's more like a rule that you need to follow. Now, let's look at some examples here.

  • I am supposed to learn English. Now here, probably, you have taken a job and you have

  • a choice but it's more like an obligation, where your boss has said, that you know what.

  • If you want to good in your career, it's important for you to learn English. So it's more like

  • an obligation to you and that's why you use the word supposed to. So, I'm supposed to

  • learn English. So it's more like an obligation. Let's understand this better by looking at

  • another example, which is, we are supposed to submit the reports by tomorrow. So again,

  • it's more like an obligation, probably your clients are waiting for you and there will

  • be consequences but it's not going to be very bad but yes, it's more like an obligation.

  • It's more like you have to do this. So we are supposed to submit the reports by tomorrow,

  • okay. Then the last example that I have for you, using the word supposed to, is you are

  • not supposed to talk loudly in a hospital. Of course, if you start speaking loudly, patients

  • are going to be disturbed. It's not a place where you can giggle or it's not a place where

  • you can talk loudly or on top of your lungs. You are supposed to maintain silence. So it's

  • more like a rule that you need to follow or an obligation that you need to follow and

  • that's why you use the word supposed to when you are talking about this. So, you are not

  • supposed to talk loudly in a hospital. Alright, so you got the difference between have to

  • and supposed to. Have to can be used, just the way, we use the word, must, where you

  • have no choice. Whereas, supposed to is used more like an obligation or like a rule that

  • you need to follow. Now let's understand, how we use the word, ought to in English.

  • Now, let's understand how do we use ought to in English. Now ought to is used, in a

  • situation where it's not an obligation, where you have a choice. So, it is not as strong

  • as the word must. Like we learned, when you use the word must or have to, then you don't

  • have a choice. When you use supposed to, then it's more like an obligation but when you

  • end up using ought to, it is not strong as have to or supposed to. So here, it's more

  • like an advice or a suggestion that you make. Now you also need to make a note that when

  • you end up using ought to, you actually do not use it in questions or in negative sentences.

  • So no using, ought to for questions or for negative sentences. Okay, so it's just a thing

  • that you need to make a note of so that you can speak or use these words confidently in

  • English. Now to understand this better, we are going to look at some examples. The first

  • one is, I ought to learn English. Now remember we learned, I have to learn English because

  • probably, you are in an English speaking country and you have no choice, the second one was

  • like, I am supposed to learn English because it's more like an obligation. Your boss has

  • asked you to but when you say that I ought to learn English, then probably you a choice.

  • Probably you just want to learn a new language. You know, you have this fantasy of learning

  • English. So you're saying, I ought to learn English. So, it's not an obligation, it's

  • not a must thing to do but yes, it's like my choice, whether I want to do it or not

  • and that's why, you are using, ought to, okay. Let's look at another example, which is, I

  • ought to help my mom with the chores. Okay, now if I help my mom with the chores, she'll

  • be really happy but there won't be major consequences if I don't help her with the chores, right?

  • Like she's not going to be very mad at me or she's not going to throw me out of the

  • house because I did not help her with the chores. So it's like, I am doing this willingly

  • and it's my choice, whether I want to help her or not and that's why, I am using the

  • word, ought to. Okay and then the third example that I have for you is, I ought to revise

  • for my exams but I am too tired to do that. Now, probably, tomorrow I have my exam and

  • I need to revise but I am kind of prepared for the exam and I am too tired right now

  • to go through it or revise the lessons. So, it's my choice, it's okay if I don't even

  • revise it. It's okay if I just wake up tomorrow morning and do it because I am too tired right

  • now and it's not like a must thing and that's why, I use the expression ought to, okay.

  • So this is the way, you will use the expression or the word, ought to in English. So just

  • understand, that the difference is really, really very simple. Have to is a must thing

  • to do, you have no choice, supposed to is more like an obligation, whereas ought to,

  • is more like a suggestion or an advice and you have your choice, whether you want to

  • do it or not. Okay, so let me know, how much do you score in the test and I'll be back

  • with a new lesson soon, till then, you take care.
