When it comes to writing numbers ordinally, such as 1st, 2nd, 3rd, there is a clear pattern to follow. However, things can get a bit confusing when it comes to numbers that end in “1” such as 91. Is it correct to write it as “91st” or should it be “91th”? Let’s dive into this topic and find out the correct usage.
The proper way to write the ordinal form of the number 91 is “91st.” This is because when we write numbers ordinally, we add the appropriate suffix to the cardinal number. In most cases, this involves adding “st,” “nd,” “rd,” or “th” to the number, depending on the final digit.
For the numbers that end in digits 1, such as 1, 21, 31, and so on, we use the suffix “st.” For example, “1st,” “21st,” and “31st” are all correctly written ordinal forms. This rule follows a pattern that is easy to remember and apply.
On the other hand, numbers ending in digits 2, 3, and other numbers from 4 to 9 use the suffix “th.” For instance, we have “2nd,” “3rd,” “4th,” “5th,” and so on. This pattern applies to the majority of numbers and is widely accepted.
Now, let’s take a closer look at the number 91. As it ends in the digit “1,” we follow the rule of adding “st” to create the ordinal form. Therefore, the correct way to write it is “91st.” This applies to all numbers that end in “1” when writing ordinals.
To further clarify, let’s compare the correct usage with the incorrect one. If we were to write “91th,” it would be contrary to the established pattern and could confuse the reader. It would be inconsistent with the proper forms, such as “1st,” “21st,” and “31st.” Such inconsistency can undermine the clarity and accuracy of our writing.
Here’s a list of examples that illustrate the correct usage of “91st”:
1. He finished the marathon in 91st place.
2. The 91st chapter of the book explores the theme of love.
3. In the 91st minute of the game, the winning goal was scored.
4. She was the 91st person to complete the puzzle.
By using “91st” in these examples, we adhere to the standard rules of ordinal numbers, ensuring consistent and accurate communication. It is crucial to maintain this consistency to avoid any confusion or misunderstanding when writing numbers in their ordinal forms.
In conclusion, the correct way to write the ordinal form of the number 91 is “91st.” Following the established pattern for ordinal numbers, we add the suffix “st” to numbers that end in “1.” Using “91th” would be incorrect and inconsistent with the standard rules. So, let’s remember this rule and apply it consistently in our writing to ensure clarity and accuracy.
