Are you planning to take your girl out for a night for a date with her? Then you are
obligatory to bring her back home safe but what does it mean to be obliged? Or what does
it mean to be obligatory about something? Stay tuned in this lesson with me Michelle
to find out, what it means to be obligatory?
Hi, so it means we are learning about what it means to be obligatory? So as I told you
if you're taking your girl out for a night, you're obligatory to bring her back home safe
but what does that mean? That means it's your duty to bring her back home safe. Yes, that
is the exact meaning of the word, obligatory means it's your duty or commitment, duty or
commitment. But is this the only way to express obligation? Should we only use the word obligatory
or obligation? No, there are other ways to express the same word.
Let’s look at the first phrase. I have to teach you English. Why do you think it's important
for me to teach you English? Because it's my duty as a teacher to teach you English.
It’s my duty or my commitment. So here, the word, have to means that I'm obliged and
it's my duty to teach you English. I have to teach you English. As you may already know
that there's a contraction of these two words, I have becomes I've, in a contraction but
can you contract two words when you're talking about obligation? Can you say, I've teach
you English? No, then it's no more a duty because your emphasis is not on the word,
have. So, whenever you're expressing an obligation, make sure you never contract your have because
then it loses its meaning for obligation. So, I have to teach you English. Here the
stress is on the word, have in the sentence and that describes whether your sentence is
obligatory or not.
Let’s look at the next phrase. I've got to, that should your spirit when you're watching
this video. I've got to learn English because I want to go abroad. So here, you're showing
your personal obligation. I have to learn English because I want to go abroad. So is
telling you that you must learn English? No, this is something that you’re feeling personally.
This is your personal goal. So whenever you're talking about your personal goals and something
that you feel that you must do yourself, then you can use the word, have got. Have got,
I’ve got to learn English. Here you're talking about your personal goal. It’s a self-realization.
Great, now let's look at the next phrase. You must, you must go to the doctor, you're
looking very sick. If you know someone who's not looking good and you think that person
is not doing well, then you must insist that they should go to the doctor. So the word
must shows that we are trying to put impositions on someone. This is not a self-realization.
Maybe I don't think that I need to go to the doctor but someone else is telling me. So
they are insisting me. When trying to insist something upon someone, you can use this phrase.
You must go to the doctor or you must work hard to achieve your aims. This is used for
impositions. I hope you can understand the difference that have got to should be used
for self-realization and you must, should be used when you're imposing something or
imposing an obligation on another person. And when you're imposing an implication upon
yourself, an obligation upon yourself, you'll use have got to.
Let’s look at the 4th one. It is obligatory. So as I told you, in the beginning of the
video that, if you're taking your girl out, it is obligatory that you bring her home safe
and there’s another situation. Let’s say someone waves at you, what do you do in return?
Do you keep your hands down and not wave back at them? No, you always wave back at them
because you have that urge. You know that it is a social custom. So we use the word,
obligatory when we are talking about a social custom that you must follow. It’s obligatory
for a social custom. So waving back at someone or saying, thank you or you're welcome and
being polite. It is all obligatory.
Let’s look at the next one. It is necessary. How is this different from obligatory? Should
there be any difference? Well, there is a difference? Here we are talking about a social
custom but as you may have guessed from the word, necessary, we are talking about a need
here. So, one fine day, if you're late and you need a taxi, you could say, it is necessary
that I get a taxi but what if you don't get a taxi? Would you not be able to do without
it? Not really, I think you can board a train rather. So, it is necessary, is used when
it's your need but you can do without it, used for a need but if the need is not fulfilled,
you can still manage without it.
Let’s look at the next one. You had to, so you had to is the past form of the verb,
must. so here we are saying, you had to, it is a past form for the verb, must in a way,
that if your friend was sharing with you about his financial crunch and he says that, I was
working overtime cause I was running out of money. So, you could say, you had to work
over time because you were running out of money. If you're talking about the same situation
in the present, you'd say, you must work over time if you are running out of money but when
you're talking about in the past, you use the word, had to. You had to, past for must.
Let’s look at the next one. I'll have to. So I'm running short of money right now, so
what will I have to do? I'll have to borrow some money. This is the future form of the
word, must. Like had to, is the past for must. The same way, I'll have to is the future for
must. So, I'll have to borrow some money because I'm running short of it. Future for must.
Here is the last phrase for you. It’s mandatory. So we've seen the phrase it is, obligatory.
It is necessary. It is mandatory. We’ve seen the difference between obligatory and
necessary from a social custom to a need but what is mandatory. So we use the word, mandatory.
I'll give you a situation for that. When you see the traffic signal turning red, it is
mandatory that you stop your car. Is it a social custom? No, is it a need? No, it is
by law that you must stop. So, mandatory is used when you're talking about a law. Used
for a law that must be fulfilled.
I suggest that you should watch all of my other videos to learn English and to do much
well at English. So what am I trying to do right now? If I'm saying, that you should
watch my videos is it an obligatory situation? It’s similar but I'm actually advising you.
So, do not confuse advising with obligation. An obligation is talking about a duty or a
commitment, which could be self-realization or an imposition by other people. I hope to
see you soon in another lesson, thanks so much for watching, bye.
