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.
