Definition of Ordinal Numbers

Ordinal numbers are numbers that express the rank or order of items. They are used to denote positions in a sequence, such as first, second, third, and so on. The main characteristics of ordinal numbers include:

Indicating order rather than quantity.
Typically formed by adding a suffix to cardinal numbers (1st, 2nd, 3rd, etc.).
Used in various contexts, including dates, rankings, and lists.

The Correct Form: 23rd

The correct form of the ordinal number for 23 is "23rd." This follows the standard English rules for forming ordinal numbers. The suffix "rd" is added to the cardinal number 23, which indicates the twenty-third position in a sequence. Here are some key points regarding "23rd":

It is used to describe the position of something that comes after the twenty-second and before the twenty-fourth.
Commonly used in dates, such as "March 23rd."
It can also be used in rankings, for example, "She finished in 23rd place."

The Incorrect Form: 23th

On the other hand, "23th" is considered incorrect in standard English usage. The primary reason for this is that the suffix "th" is not applicable to the number 23. Here are some points to note about the incorrect form:

The use of "th" is reserved for numbers that end in 0, 4, 5, 6, 7, 8, and 9, but not for numbers ending in 1, 2, or 3.
Using "23th" can lead to confusion and is often viewed as a grammatical error.
It is essential to adhere to the correct form to maintain clarity in writing.
