ORDINAL NUMBERS

Recently you completed homework about Halloween and most of them were excellent, but we noticed many of you have problems using the date properly. When we use the date we us what is known as ordinal numbers. You use them in Czech and just like you, we use them in English and in many ways they are easier.

You can all count in English using cardinal numbers but when we talk about dates, places in a sport competition, classes in a school etc, we use ordinal numbers. You have certainly been taught them before but maybe you have forgotten them so here is a little revision:

Cardinal Numbers

1

2

3

4

5

6

7

8

9

10

one

two

three

four

five

six

seven

eight

nine

ten

Easy right? But what about when we want to talk about the date?

We can’t say one of January or ten of September, just like in Czech you don’t say jeden leden or deset září , so instead we use…

Ordinal Numbers

1st

2nd

3rd

4th

5th

6th

7th

8th

9th

10th

first

second

third

fourth

fifth

sixth

seventh

eighth

ninth

tenth

Also pretty easy. Mostly we just add -th at the end of the numbers, except numbers ending in 1, 2 or 3 (but NOT 11, 12, 13) Therefore we say the first of January or the tenth of September. When we get to numbers like 21, 22, 23, 31, 32, 33 etc they just become 21st (twenty-first), 22nd (twenty-second), 23 (twenty-third), etc. So when we talk about Halloween, we say it is on the 31st (thirty-first) of October.
