When it comes to writing dates, the question of whether to use “27th” or “27rd” might seem confusing at first. However, with a little explanation and some examples, it becomes clear that “27th” is the correct choice. Let’s dive into the reasons why.
The main reason why “27th” is the correct form is that it follows the standard rules of ordinal numbers. In English, ordinal numbers are used to indicate the position of something in a series. They are formed by adding the suffix “-th” to the cardinal number (e.g., first, second, third). This is true for all numbers ending in “3” except “13th” and “23rd,” which have irregular forms.
To demonstrate this, let’s take a look at some examples:
1. 1st – first
2. 2nd – second
3. 3rd – third
4. 4th – fourth
5. 5th – fifth
6. 6th – sixth
…
…
…
27. 27th – twenty-seventh
As you can see, the pattern is consistent. All the numbers ending in “3” take the “-rd” suffix to form their ordinal counterparts, except for “13th” and “23rd.” Therefore, when writing the date “27th,” we follow the standard rule and use the “-th” suffix.
Using “27rd” would be incorrect because it deviates from this established pattern. It might create confusion for the reader and could lead to a lack of clarity in written communication.
Correct: “We will meet on the 27th of July.”
Incorrect: “We will meet on the 27rd of July.”
Furthermore, using “27rd” does not align with the conventions of English grammar and style. English language learners often struggle with the irregularities and exceptions present in the language, so it is important to ensure consistency and accuracy when teaching or learning English.
In conclusion, the correct way to write the ordinal number for “27” is “27th.” By following the standard rules for forming ordinal numbers, we maintain clarity, consistency, and accuracy in our written communication. So the next time you’re writing a date or referring to a position in a series, remember to use “27th” and avoid the erroneous form of “27rd.”
