When it comes to expressing ordinal numbers, such as “70th” or “70st,” it’s important to use the correct form in order to convey the intended meaning. In this case, the correct form is “70th.” Let me explain why.
Ordinal numbers are used to describe the position or order of something in a sequence. They often end in “-th,” “-nd,” “-rd,” or “-st,” depending on the last digit of the cardinal number they represent. For numbers ending in 1, 2, or 3 (except for 11, 12, and 13), we use the suffixes “-st,” “-nd,” and “-rd,” respectively. For all other numbers, including 70, we use the suffix “-th.”
To illustrate this, let’s consider some examples. If we have a group of people and we want to identify the person in the 70th position, we would correctly say “He is the 70th person in line,” not “He is the 70st person in line.” Similarly, if we have a list of countries ranked by population, and we want to refer to the country in the 70th position, we would say “It is the 70th country on the list,” not “It is the 70st country on the list.”
Using “70st” instead of “70th” is not only grammatically incorrect, but it also sounds unnatural and can lead to confusion. It is important to follow the established rules of the English language to ensure clear and effective communication.
Consider the following question: “Which of these two items is the 70st?” This question would likely puzzle most people, as “70st” is not a recognized form. However, if we rephrase the question as “Which of these two items is the 70th?”, it becomes immediately clear that we are referring to the item in the 70th position.
Just like using the correct form of an ordinal number is essential for comprehension, using proper grammar and language conventions is crucial in the context of language exams like IELTS. Examiners are looking for candidates who can demonstrate their mastery of English, including the correct usage of ordinal numbers.
So remember, when expressing the 70th position or any other ordinal number, use the appropriate suffix “-th” instead of mistakenly using “-st.” By doing so, you will not only showcase your language skills but also ensure that your message is understood clearly and accurately.
In conclusion, the correct form is “70th,” and “70st” should be avoided. Following the established rules of grammar and language conventions is essential for effective communication and success in language exams like IELTS. So, let’s embrace the correct usage and confidently express ordinal numbers in our conversations and writings.
