# Ordinal Numbers

## Introduction

**Ordinal numbers** express numerical sequences, positioning elements in a list.

## Form

**Ordinal numbers** are usually preceded by the definite article **the** and they are usually placed after the verb.

**Ordinal numbers** are made by adding **-th*** to the **cardinal numbers** (1 – 10):

*1st** –*First**2nd** –*Second**3rd** –*Third**4th*–*Fourth**5th** –*Fifth**6th*–*Sixth**7th*–*Seventh**8th** –*Eighth**9th** –*Ninth**10th*–*Tenth*

*The exceptions (also twelve = twelfth).

## Example

*He was the*. /**first**on the list*He was the***1st**on the list.*It’s my*/**second**time in Sweden.*It’s my***2nd**time in Sweden.*I want the*/**third**cake.*I want the***3rd**cake.

## Use

We use **ordinal numbers** to express the position of something in a sequence. Unlike cardinal numbers, which are used to express the quantity of something.

## Summary

**Ordinal numbers** are used to position elements in a sequential order.

Ordinal numbers are made by adding **-th** to the cardinal numbers: * first*,

*,*

**second***,*

**third***,*

**fourth****,**

*fifth*,*sixth**,*

**seventh***,*

**eighth***and*

**ninth***.*

**tenth**For example:

— “*It’s my fifth time in Spain*.” = This is the current number of times I have visited Spain and I am there now (

*= ordinal number).*

**fifth**♦ “

*I’ve been to Spain*.” = The total number of times I visited Spain and I am not there anymore (

**five**times*= cardinal number).*

**five**NOTE: 1, 2, 3, 5, 8, 9 and 12 are **exceptions** (as their ordinal numbers don’t follow the general formation rule: * first*,

*,*

**second***th*,

**ird***fi*,

**fth***eight*,

**h***nin*and

**th***twel*).
