Cardinal & Ordinal Numbers in English! In English, cardinal numbers are the numbers we use to count things. There are also ordinal numbers, which are used to show the order of things. In this blog post, we will look at how to form and use both types of number in English. Let’s get started!

### What are Cardinal Numbers?

Cardinal numbers are the numbers we use to count things. For example, if we wanted to count the number of people in a room, we would use cardinal numbers. Cardinal numbers can be used for counting both tangible objects and abstract concepts.

### How to Form Cardinal Numbers?

In English, cardinal numbers are usually written as numerals (1, 2, 3, etc.). However, there are some exceptions to this rule. For instance, the number 10 can also be written as “ten.” The number 100 can be written as “one hundred.”

When writing large numbers, it is standard to use commas to separate groups of three digits. For example, the number 1,000 can be written as “one thousand.”

### How to Use Cardinal Numbers?

In order to use cardinal numbers, you first need to know how to form them. Once you know how to form them, you can then use them in sentences. For example, the sentence “I have one cat” would use the number 1 as a cardinal number. The sentence “I have three cats” would use the number 3 as a cardinal number. As another example, the sentence “The election is on November 8th” would use the number 8 as a cardinal number.

### What are Ordinal Numbers?

Ordinal numbers are used to show the order of things. For example, if we wanted to say that someone was the third person in line, we would use ordinal numbers. Ordinal numbers can be used for both tangible objects and abstract concepts.

### How to Form Ordinal Numbers?

In English, ordinal numbers are usually written as numerals with the suffix “-th” added to the end (1st, 2nd, 3rd, etc.). However, there are some exceptions to this rule. For instance, the number 10 can also be written as “tenth.” The number 100 can also be written as “hundredth.”

When writing large numbers, it is standard to use commas to separate groups of three digits. For example, the number 1,000 can be written as “one thousandth.”

### How to Use Ordinal Numbers?

In order to use ordinal numbers, you first need to know how to form them. Once you know how to form them, you can then use them in sentences. For example, the sentence “I am the first person in line” would use the number 1 as an ordinal number. The sentence “I am the third person in line” would use the number 3 as an ordinal number. As another example, the sentence “The race is on April 22nd” would use the number 22 as an ordinal number.
