Unit 7.1

# Ordinal numbers

## Introduction

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

## Form

**Ordinal numbers** are made by adding **-th*** to the **cardinal numbers** (1 – 10) except in some occassions marked:

- 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

*It’s my*.**second**time in Sweden*He was the*.**first**on the list*Our house is the*.**fourth**on the left

## Use

We use **ordinal numbers** to show the position of something. They can be placed **after the verb** **or** working **as a noun** when they are only accompanied by the article ‘**the’** with **no noun after** the ordinal number.

## Summary

**Ordinal numbers** differ from **cardinal numbers** as they are used to position elements on a list. Ordinal numbers are made by adding **-th** to the cardinal numbers: **first**, **second**, **third**, **fourth**, **fifth, sixth**, **seventh**, **eighth**, **ninth** and **tenth**.

For example:

— “*It’s my fifth time in Spain.*” = This is the current number of times that I’m in Spain (

**fifth**= ordinal number).

♦ “

*I’ve been to Spain*” = The total number of times I’m in Spain (

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

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**th** and twel**fth**).

Let’s revise this content within the {Form} section. Take a look at the {Example} section that shows its use within a context.
