    What is adjective of number?

    Number adjectives are used to show the precise countable number of things and people. They can show quantity, order, and position of nouns. Unlike quantity adjectives, they can be used only with countable nouns. 

    Cardinal numbers

    Cardinal numbers are numbers used to directly refer to a quantity of something and ones we use on a daily basis in our speech when talking about the exact quantity of something.  

    Cardinal numbers example

    • I passed my exam with 98% score.
    • Can you buy two apples, please?
    • She would like to order five steaks.

    Forming hundreds follow the same structure as the table with twenty above. However, at the front, you add what amount of a hundred it is + and. 

    Example

    • 32.98% - Thirty-two point ninety-eight percent

    What are ordinal numbers?

    Ordinal numbers are used to show us how something or someone is ranked on a list and what their exact position is. They are only used to refer to a position but not a quantity which is what we use cardinal numbers for. Majority of the ordinal numbers follow the same structure with the exception from the written version of 1 to 4 as we can see from the table below.

    Ordinal numbers examples

    • She was my first girlfriend.
    • This is my second attempt.
    • We completed the third assignment.
    • My final position was thirty-fourth.
    • It is my sixty-eighth anniversary. 

    Ordinal numbers grammar

    Ordinal numbers and their written form are rather specific thus it is important to pay attention to ensure the correct form is written. 

    1. The most special cases are the first three numbers:

    First Twenty-first Fifty-first Two hundred and first
    Second Twenty-second Sixty-second Three hundred and second
    Thid Twenty-third Sixty-third Four hundred and twenty-third

    As we can see from the table the form for firstsecond, and third remains a constant regardless of where it is used in a positional manner. 

    2. The case of 11, 12, 13: While the ending number of them is the same as the one we discussed in the first example they are exception to the rule and always needs to be written in one specific way. 

    • Eleventh
    • Twelfth
    • Thirteenth

    Cardinal and ordinal numbers

    The main diffrence between the two is that cardinal numbers directly refer to a quantity whereas ordinal numbers only refer to a position but not quantity. 

    However, the two work hand in hand as excluding the exception all of the other ordinal numbers are formed by adding the suffix -th to the cardinal number. 

    Example:

    Cardinal number Ordinal number
    Seven Seventh
    Nine Ninth
    Twenty-four Twenty-fourth
    Thirty-five Thirty-fifth
