The correct ordinal number to use after the number 3 is “3rd.” Even though “3th” may seem like a plausible option, it is not grammatically correct in the English language. Let me explain why.
In English, 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 (numbers used for counting). For example, “first” is the ordinal form of “one,” “second” is the ordinal form of “two,” and so on.
Now, when it comes to the number 3, we add the suffix “-rd” to make it ordinal. Hence, “third” is the correct ordinal form for the number 3. This pattern is consistent with other numbers ending in “3,” such as 13th, 23rd, 33rd, and so forth.
To further illustrate this, let’s consider a few examples:
1. She came in 3rd place in the race.
2. Today is her 3rd birthday.
3. The 3rd paragraph of the article provides valuable insights.
4. I’m going on vacation from the 3rd to the 10th of July.
In each of these examples, “3rd” is used to indicate a specific position, order, or date. It is clear, concise, and easily understood by native English speakers.
On the other hand, if we were to use “3th” instead, it would create confusion and sound awkward. It would not follow the established grammatical rules for forming ordinal numbers. Native English speakers would likely perceive it as an error or typo rather than a valid usage.
Language experts and style guides universally recommend using “3rd” as the correct ordinal form for the number 3. The use of “3th” is not supported by any reputable grammar rules or conventions.
In conclusion, when it comes to indicating the position or order of something in a series, such as the number 3, “3rd” is the proper and accepted form. Remember to stick with the established pattern of adding “-th” to the end of cardinal numbers to create ordinals. So, next time you need to express the third position or order, confidently use “3rd” and avoid the non-existent “3th.”
