When it comes to expressing numbers in written English, there are sometimes confusing exceptions and irregularities that can trip up even seasoned writers. One such example is the use of ordinal numbers, which indicate the placement or order of items. In this case, we’re faced with a common dilemma: should we write “10th” or “10st”? Let’s explore this question and clarify which option is correct.
To begin, let’s establish that the correct form is “10th.” The ordinal number “10th” is the appropriate way to express the number ten in a sequence. This is because the suffix “-th” is used to form ordinal numbers for most numerals, including all numbers from 4 to 20, as well as all multiples of 10. For instance, we say “fourth,” “fifth,” “eleventh,” “twelfth,” “twentieth,” and “thirtieth.” The same logic applies to “tenth.”
To further illustrate this point, let’s consider some examples:
1. Sarah finished in 10th place in the race.
2. The 10th of January is a national holiday.
3. This is my 10th attempt at solving the puzzle.
In each of these sentences, “10th” accurately conveys the numerical position or order. It seamlessly fits into the sentence structure, allowing the reader to understand the context without any confusion. Using “10st,” on the other hand, would be incorrect and may cause the reader to stumble or question its validity.
Now, let’s dive deeper into the rationale behind this rule. The use of “-th” as an ordinal suffix primarily stems from Old English, the earliest form of the English language. In Old English, ordinal numbers were formed by adding “-th” or “-eð” to the cardinal number. Although English has undergone numerous changes over time, this particular rule has endured and remained consistent.
To solidify our understanding, we can also look at some other exceptions and patterns in English ordinal numbers. For example, the numbers 1, 2, and 3 have unique ordinal forms: “1st,” “2nd,” and “3rd.” These have historical roots and are exceptions to the general rule. However, from the number 4 onward, “-th” remains the standard suffix.
In conclusion, when expressing the ordinal form of the number 10, it is essential to use “10th.” This aligns with the standard rules of English grammar for forming ordinal numbers. By using the correct form, we ensure clear communication and effective writing. So, the next time you encounter the dilemma of “10th” or “10st,” remember that “10th” is the correct choice. Don’t let the exception confuse you or your readers.
