When it comes to ordinal numbers, the 10th is the correct form to use. The use of “10rd” is incorrect and is not recognized in standard English grammar. Let me explain why this is the case.
Ordinal numbers are used to indicate the position or order of something in a series. They are formed by adding the suffix “-th” to cardinal numbers. For example, “four” becomes “fourth,” “eight” becomes “eighth,” and “twelve” becomes “twelfth.” The same rule applies to the number 10, which should be written as “tenth.”
Here are a few examples that demonstrate the correct usage of “10th”:
1. “He finished in 10th place in the race.”
2. “Please turn to the 10th page of the book.”
3. “The 10th of September is my birthday.”
As you can see, the correct form “10th” is used to express the idea of being in the tenth position, order, or occurrence.
Now, let’s address the incorrect use of “10rd.” In the English language, there is no ordinal number formed by adding “-rd” to a cardinal number. The suffix used for the numbers ending in 3 is “-rd” in the context of expressing fractions (e.g., “third” in “one-third”), but not in ordinal numbers.
To further illustrate this point, let me provide you with examples that demonstrate the incorrect usage of “10rd”:
1. Incorrect: “He finished in 10rd place in the race.”
2. Incorrect: “Please turn to the 10rd page of the book.”
3. Incorrect: “The 10rd of September is my birthday.”
As you can see, these sentences sound awkward and are grammatically incorrect. The correct form “10th” should be used instead.
To summarize, “10th” is the correct ordinal form for the number 10. The use of “10rd” is incorrect and not recognized in standard English grammar. It is essential to adhere to the established rules of grammar to effectively communicate in English. So remember, when it comes to expressing the tenth position or order, always use “10th” and avoid “10rd.”
