When it comes to the ordinal number for “11,” there is often confusion between “11th” and “11st.” In this article, we will explore which form is correct and why.
To put it bluntly, the correct ordinal number for “11” is “11th.” The use of “11st” is incorrect and considered grammatically wrong. Let’s learn the explanation and examples to understand why this is the case.
When forming ordinal numbers in English, we generally add the suffix “-th” to the cardinal number. This rule applies to most numbers, including “11.” For example, we write “1st” for “first,” “2nd” for “second,” “3rd” for “third,” and “12th” for “twelfth.” Following this pattern, the correct form for “11” should be “11th.”
The incorrect form “11st” might be a result of people trying to apply the same rule used for numbers ending in “1,” such as “1st,” “21st,” or “31st.” However, it is important to note that “11” does not fall into this category. Instead, it should be treated like other numbers and take the “-th” suffix.
To further understand this, let’s consider a few examples. Imagine you are discussing a series of dates with a friend:
1. “July 1st”
2. “June 2nd”
3. “August 3rd”
4. “September 11th”
In the fourth example, we correctly use “11th” to express the eleventh day of September. If we were to use “11st” instead, it would be grammatically incorrect and create confusion for the reader or listener.
Let’s consider another scenario. You are discussing rankings with a group of friends:
1. “He came in 1st place.”
2. “She finished 2nd in the race.”
3. “They achieved 3rd position.”
4. “We secured 11th position in the competition.”
Again, in the fourth example, using “11th” correctly conveys the eleventh position obtained by “we.” If we were to use “11st” here, it would clearly stand out as an oddity among the other grammatically correct examples.
Just as “11th” is the only acceptable ordinal form for “11,” the same principle applies to all numbers ending in “1.” Only numbers ending in “1” follow the irregular rule of using the “-st” suffix for ordinals (e.g., “21st,” “31st,” “41st”).
In conclusion, the correct ordinal form for “11” is “11th.” The incorrect usage of “11st” is a common mistake resulting from incorrect application of the ordinal rule. By understanding the general rule for forming ordinal numbers and recognizing exceptions like numbers ending in “1,” we can avoid confusion and maintain grammatical accuracy in our writing and speech. So, let’s bid farewell to “11st” and embrace the correct form, “11th.”
