89th or 89st – Which is Correct?

When it comes to using ordinal numbers, such as “89th” or “89st,” it is essential to understand the correct usage to ensure accurate and effective communication. In this case, the correct ordinal number to describe the 89th position is “89th.” The addition of “st” after 89 is incorrect and should be avoided. Let’s explore the reasons behind this and provide some examples to illustrate this point.

To understand why “89th” is correct, we need to take a closer look at how ordinal numbers are formed in English. Ordinal numbers are used to indicate the order, rank, or sequence of something. In most cases, they are formed by adding the suffix “-th” to the cardinal number. For example, we say “first” for 1, “second” for 2, “third” for 3, and so on. This pattern continues for numbers ending in digits other than 1, such as “fourth,” “fifth,” “sixth,” and “seventh.”

However, when cardinal numbers end with the digit 1, we do not simply add “-th” to form the ordinal number. Instead, we use the suffix “-st.” For example, we say “first” for 1, “thirst” for 31, “forty-first” for 41, and so on. This “-st” suffix, which is used for numbers ending in 1, is an exception to the general rule of adding “-th.”

In our specific case, 89 does not end in 1, so the general rule applies, and we add “-th” to form the ordinal number. Therefore, it should be “89th,” not “89st.” This applies to any number ending in 9; for example, we say “29th,” “49th,” “69th,” and so on.

To further illustrate this point, consider the examples below:

1. John finished in the 89th position.
2. The 89th chapter of the book was particularly insightful.
3. She has been waiting for the 89th bus for over an hour.
4. They celebrated their 89th anniversary with a grand party.
5. The 89th contestant gave a mesmerizing performance.

In all these examples, “89th” is used correctly to denote the ordinal position or sequence. Using “89st” instead of “89th” would not only sound odd but also be grammatically incorrect.

In conclusion, when it comes to using ordinal numbers, such as “89th” or “89st,” it is crucial to follow the correct formation. In the case of 89, the correct ordinal form is “89th.” This reflects the general rule of adding “-th” for most numbers and the exception of using “-st” for numbers ending in 1. By understanding and applying these rules, we can communicate accurately and effectively in English. Now that you know the correct form, feel free to impress others with your impeccable grammar!
