  • Ordinal numbers in English

    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

    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 first, second, 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
