Hi,everybody.I am Niharika,your tutor for today’s lesson.
Thank you for clicking on this video here.
We are gonna learn about articles:“a”,“an”,“the”.
We are going to learn about these articles.
Now these articles are little difficult,little confusing and have many rules.
However, I’m going to help you with the basics so that you know how can use these articles in your sentences.
OK,so we will look at the first article here,that is “a”.
Now before I start with it,let me also tell you that articles are used for nouns.
Always remember this,they are used for nouns.
So let’s look at a sentence here,and then I’ll explain you what exactly this article is.
“She wore a hat”.Now here “a” is your article.And “hat” is your noun.
Ok,so “she wore a hat”.Now if I come to tell you “she wore a hat”,you don’t know what hat I’m talking about.
Maybe it’s a pink hat,or maybe it’s a round hat.
So nothing in particularthat I’m talking about.
So it’s just a general idea,that “she wore a hat”.
So nothing is definite. So basically “a” is your indefinite article.
It is also known to us that it’s indefinite article.
So that is when you are not talking about something specific,just in general.
Ok, I will just write it down for you.All right.
Ok,so “she wore a hat”as it again,“a hat”,just in general,“she wore a hat”,that I’m talking about.
We also see another sentence here,“I saw a star in the sky last night”.
Now here “a” is your article,and “star” is your noun.
Ok,remember this,“star”is your noun.
There are millions of stars in the sky,right?
So here we are using “I saw a star”,just nothing in particular,but I just spotted star.
And that’s why I’m telling it to you.
So it is an indefinite article here.All right.
Another thing that I would like to tell you about this article is that it is used for a singular noun.
Ok,I’ll write it down.It is used for a singular noun.
So you would not to say,she wore a hats.Ok,that’s incorrect.
Ok,so you would not to say,I saw a stars,that doesn’t sound right,doesn’t it?
So it’s always used for a singular noun.So I want a cookie.Ok,I want a cookie,simple,right?
So it’s not a specific cookie that you are looking at,you are not gonna say that I want the third cookie out of this packet,or the fourth cookie,it’s just a cookie,in general.right?
So we would also look at the article “the” here.Now when do we use the article “the”?
I have written down the same sentence here,Ok,but with “the”,here,“she wore the hat”.
Now “the” here is your article,the hat.
And basically which means you know what hat I’m talking about.
Maybe you know it’s a hat that we discussed about it last week,and then she finally bought it.
So I am mentioning to you that “she wore the hat”,maybe a hat that we were making fun of.
Or maybe the pink hat that she got it last week.So something like that,so you know it specifically that you are talking about “the” hat,which hat,I’m sorry.
So here “the” would act as your definite article,something in particular,something specific.
All right,please remember this.
I would also like to mention something in the sentence,I mean let me first go through the sentence.
“I saw the Northpole star in the sky last night.”
Now here “the” is your article,your definite article.
And “Northpole star” is the specific star that you spotted.
Again,here,you know there are millions of stars,and you just spotted some star,you just spotted a star,so that’s why you used “a” here.
And here you know that you spotted “the Northpole star”,and therefore,you are using this article “the” here.
Now if you notice in both these sentences,we are using “the” here also,right?
“the”now,why?I’ll tell you.“I saw a star in the sky last night”.
How many skys do we have?Ten?Eleven?NO.There is just one sky,right?
Just one sky in the universe.So sky here is acting as your noun,and “the” is the article because you know that you spotted the star,a star in the sky.
Ok,I hope you are clear with this.you know when to use “a”,“a”will be used when you do not have an idea about intend,it’s just in general that she talking about.
Thereas “the” you would use it when you know what you are talking about,particularly if you talking about something you know it,and that’s exactly when you use the article “the”.
So now let’s look at the article “an”.All right. So now let’s look at the article “an”.
Just like the article “a” and the article “the”.How they are used for nouns?
Similarly,”an” is also used for nouns.And once again,just like “a”,it is an indefinite article,OK.
So when we are talking about something,all right,we are talking about something.
But nothing in particular,just in general.
So we will have to look at some sentence here.
“I bought an umbrella”,here “an” is your indefinite article,but why are we not saying “I bought umbrella”?
That sounds correct to you,“I bought umbrella”.No,that’s not correct.I’ll tell you why.
Because umbrella is a noun,however,it starts with the letter“u”,and “u” is you vowels.
So here “an” is a very,it’s a little simple article,I really love this article,because it’s easy to use, because I know that “an “ comes before a vowel.
So what are your vowels? a、e、i、o、u?
Ok,just remember that. a、e、i、o、u,OK ,these are your vowels.So it comes before a vowel.
When you look at another sentence here,“I will be back in an hour”.
Ok,“an ”is again your article ,indefinite article.
Here,now you would see that’s not a vowel.
However,it is pronounced as hour,right?
The “h” is silent,so that becomes your vowel sound.
So always remember that “an” would come befor a vowel,or a vowel sound.
Ok,so here another sentence for frame one.
“I am a honest person”? No,right,it would be “I am an honest person”.
So again here “h” is slience. “honest”is your vowel sound,that’s why you are using “I am an honest person”.
Ok, so I hope you got a clear picture when we use “a”,when we use “the”,and when do we use “an”.
And the simple one ,use vowels or vowel sounds.Ok,the words with vowel sounds.
So now as I said before,there are many many many rules when we use articles,so I am gonna get into details in our next lessons.
So I am gonna teach exceptions about all the rules.
So please do some subscriber channel and of course,for this lesson if you have any questions or inquiry,do write to us and I’ll answer it all.
Tell them you take care and have a great day.
