When it comes to ordinal numbers, such as 1st, 2nd, 3rd, etc., there is a common confusion that arises when dealing with numbers ending in “9.” Are we supposed to write “49th” or “49st”? The answer is quite simple: “49th” is the correct way to express the ordinal form of the number 49.

To understand why “49th” is correct, let’s take a closer look at the rules of forming ordinal numbers in English. Ordinal numbers are used to show the position or order of something in a series. When forming these numbers, we typically add the suffix “-th” to the base number. This holds true for most numbers, except for a few irregular forms like “first,” “second,” and “third.”

So, in the case of 49, we simply add the suffix “-th” to the base number, resulting in “49th.” This follows the same pattern we use for other numbers, such as 1st, 2nd, 3rd, and so on.

Now, let’s consider the incorrect option, “49st.” Unlike the regular pattern we discussed earlier, this form does not adhere to the rules of English grammar. In fact, placing the suffix “-st” directly after the number 49 is considered incorrect and non-standard usage.

To further illustrate this point, let’s take a look at a list of examples:

Correct usage:

– 1st

– 2nd

– 3rd

– 4th

– 5th

– …

– 49th

Incorrect usage:

– 49st

– 49rd (Not applicable in this particular case, but an example of another incorrect form)

From this list, it becomes clear that “49st” does not fit the pattern of proper ordinal number formation in English. Writing “49st” would be similar to saying “onest,” “twoest,” or “threeest,” which sound rather awkward and incorrect.

In conclusion, the correct way to express the ordinal form of the number 49 is “49th.” This follows the established pattern for forming ordinal numbers in English. By understanding the rules of ordinal number formation, we can confidently use “49th” in written and spoken English without any ambiguity. So, remember to stick to “49th” and leave “49st” behind as an incorrect and non-standard form.
