[Part 1]

Hello, everyone.

In this video, we are going to talk about ordinal numbers.

Now, ordinal numbers are different than cardinal numbers.

Of course cardinal numbers are numbers like one two three four five.

Ordinal numbers are different.

Ordinal numbers are used for expressing things like rank.

First, second, third place… uhhh… in a contest.

Or they’re used to express anniversaries.

For example, “This is my third wedding anniversary.”

And it’s also used commonly in the calendar for dates.

For example, “June first,” ahhh, “June second.”

Ok…

So this where we use ordinal numbers.

So, in this video, I’m going to teach you how to write ordinal numbers and also pronounce them correctly.

Ok…

So, we’re going to look at the first ten.

I have the first ten here.

So let’s go through them very quickly.

This is “first”…and if you notice the last two letters…I underline in blue.

Ok…

The last two letters are very important.

So, if you see first, the last two letters are ‘s-t’.

So when we want to write an ordinal number, we have number one, we must use the last two letters.

The last two letters are ‘s-t’.

So this is our ordinal number.

We should write ‘s-t’.

Ok…

So this,”first” and now we write it like this.

“First.”

And the ‘s-t’ is usually up.

Ok…

Let’s move on to “second”.

‘Second’ we see that it is ‘n-d’.

So the last two letters of ‘second’, ‘n-d’.

‘Two’, we have to put ‘n-d’.

Alright…

So now this is “second”.

“First.”

“Second.”

“Third.”

The last two letters, ‘r-d’.

So, we have to go over here…’r-d’.

“Third.”

“Fourth.”

‘t-h’…..’t-h’.

“Fifth.”

‘Five’ and again, ‘t-h’.

“Sixth.”

‘t-h’.

“Seventh.”

‘t-h’.

“Eighth.”

‘t-h’.

“Ninth.”

‘t-h’.

“Tenth.”

‘t-h’.

Ok, so you can see most of them use the ‘t-h’.

Just the “first, second, third”, ‘s-t’, ‘n-d’, ‘r-d’.

You have to be very careful.

Alright…

Look at these numbers over here.

I wrote some numbers, circled in red.

‘Three’ and ‘t-h’.

‘Three’ and ‘t-h’.

“Threeth.”

“Threeth.”

Ok, this is a common mistake.

This is obviously wrong becuase ‘three’ only has ‘r-d’.

You have to use these two letters.

This is impossible.

Ok…

So, “threeth”, impossible.

Next one.

“Sic…sic…sicond.”

Again, that is impossible cause “sixth”, “sixth” must have ‘t-h’.

So this is impossible.

And the last one.

“Ninst.”

“Ninst.”

Well, “ninth.”

“Ninth” must have ‘t-h’.

So, these are impossible.

So you have to be very careful writing these numbers.

They must use the last two letters.

Ok…

Let’s worry about pronunciation right now.

Pronunciation can be a little bit difficult, also.

So let’s go through the list.

And you should watch me and listen carefully.

So, “first.”

“Second.”

“Third.”

“Fourth.”

Ok, when I say “Fourth”, look at my tongue.

My tongue comes out.

“Fourth.”

“Fifth.”

“Sixth.”

“Seventh.”

“Eighth.”

“Ninth.”

“Tenth.”

Ok…

So, the ‘t-h’, your tongue should be coming out.

Let’s do the ‘t-h’ again.

“Fourth.”

“Fifth.”

“Sixth.”

“Seventh.”

“Eighth.”

“Ninth.”

“Tenth.”

Ok…

So these are the first ten.

You should know these.

Let’s move on to some bigger numbers.

5:15 [Part 2]

Alright, let’s continue with our ordinal numbers.

The next, after ‘tenth’, is “eleventh”.

We see the ‘t-h’ and the ‘t-h’ goes there.

“Eleventh”.

And the next one.”

“Twelfth.”

‘t-h’

And the next one.

I did not write the next ones here, but I will say them, so listen carefully.

So, “eleventh”.

“Twelfth.”

“Thirteenth.”

“Fourteenth.”

“Fifteenth.”

“Sixteenth.”

“Seventeenth.”

“Eighteenth.”

“Nineteenth.”

“Twentieth.”

Alright, let’s look at ‘twentieth’.

Ok…

So, it’s ‘twenty’.

‘TWenty’ has a ‘y’, but you can they take out the ‘y’, they put in an ‘i-e-t-h’.

This is “twentieth”.

And we would write it with a ‘t-h’.

‘Twenty’ with a ‘t-h’.

“Twentieth.”

Alright, so with the pronunication, “Twenty, Twentieth.”

“Twentieth.”

“Twentieth.”

After ‘twentieth’, “Twenty-first.”

Ok, “Twenty-first.”

And we would write ‘twenty-one’ with the ‘s-t’.

This is “Twenty-first.”

And again, I did not write the next ones here, but listen carefully.

So, “Twentieth.”

“Twenty-first.”

“Twenty-second.”

“Twenty-third.”

“Twenty-fourth.”

“Twenty-fifth.”

“Twenty-sixth.”

“Twenty-seventh.”

“Twenty-eighth.”

“Twenty-ninth.”

“Thirtieth.”

And again, like ‘twentieth’, ‘thirtieth’, no ‘y’ just ‘i-e-t-h’.

“Thirtieth.”

“Thirtieth.”

“Thirtieth.”

Alright…

And I also want to talk about the pronunciation of “twelfth”.

‘Twelfth’ is very difficult to pronounce.

If you look at it here, you see that ‘f’.

And many students try to pronounce it with the ‘f’.

“Twelfffth.”

Ok, that’s very difficult.

But what is actually more common, even with native speakers, is we don’t pronounce the ‘f’.

We just skip it.

So, for example, if we cut that ‘f’.

Imagine it is not there.

“Twelth.”

Ok, that’s a little bit easier.

You can just say “Twelth”.

“Twelth.”

Ok…

So again, “Twelfth”.

“Twentieth.”

Ok, be sure to pronounce those correctly.

Let’s move on to some bigger number.

8:02 [Part 3]

Ok, so I am sorry because I cannot write every ordinal number.

Ok…

I cannot explain every number.

So, you’re going to have to practice guessing what is the ordinal number.

And I put some numbers here and we’re going to guess whether they use ‘s-t’, ‘n-d’, ‘r-d’ or ‘t-h’.

Ok…

We only have four choices.

The first number is “fifty-six”.

So if we want to change that to an ordinal number, we have to choose one of these.

Ok…

So, “fifty-six”.

Well, we know ‘six’ is…’six’ is ‘t-h’.

“Sixth.”

And it’s going to be the same.

“Fifty-sixth.”

So, I’m going to write a ‘t-h’ there.

Let’s move on to the next number.

“Ninety-one.”

Well, what’s the ordinal number?

“Ninety-oneth?”

No.

This is going to be like ‘twenty-first’ and ‘thirty-first’.

This is going to be “ninety-first”.

Alright, the next one is “one hundred”.

So, we have to choose one of these.

“One hundredst?”

“One hundrednd?”

“One hundredrd?”

“One hundredth?”

Ok, it’s going to be the ‘t-h’.

“One hundredth.”

“One hundredth.”

Alright…

And the next number.

“One oh one. One hundred one.”

Well, this is like “ninety-first.”

This is “first” again.

“First.”

So, it’s going to be “One hundred and first. One hundred first.”

Alright…

And the last one.

“One thousand.”

We have to choose one.

Well, “One hundredth. One thousandth.”

Ok, it’s going to be the same.

Alright…

So again, I’m sorry I can’t teach every number.

Your going to have to learn how to guess correctly.

Ahhh, we’re going to do a quick test…right now.

So what I want you to do in the test is write down or think about what the correct ordinal number is.

10:14 [Part 4 – Test]

Again, just write in the ordinal number.

Number one.

“It is September twentieth.”

“It is September twentieth.”

Alright, so you should’ve written ‘twentieth’.

Number two.

“Seoul National university is ranked first.”

“Seoul National university is ranked first.”

Alright, so you should’ve written ‘first’.

Number three.

“We live in the twenty-first century.”

“We live in the twenty-first century.”

Ok, so you should write ‘twenty-first’.

Number four.

“I was born on March seventeenth.”

“I was born on March seventeenth.”

Ok, you should write ‘seventeenth’.

And number five.

“We are celebrating our twelfth wedding anniversary.”

“We are celebrating our twelfth wedding anniversary.”

Ok, so you should’ve written ‘twelfth’.

11:49 [Part 5]

Ok, I hope you did well on that little test.

Ok…

Now, ordinal numbers are important.

Again, they’re used for ranking and they’re used for the calendar, and also anniversaries.

Also, sometimes, you see book volumes use ordinal numbers.

Ok, so you should know ordinal numbers.

Now, it takes a lot of practice and self-study to truly truly master ordnial numbers.

I hope this video helped you understand them a little bit better.

And, well, that’s it.

See you next time.
