When it comes to the ordinal number for 90, the correct form is 90th. The use of “90nd” is incorrect and not recognized in standard English grammar. Let’s learn the reasons why “90nd” is incorrect and explore some examples to illustrate this point.
In English, we use ordinals to indicate the position or order of things. These ordinals are formed by adding “-th” to the cardinal number (e.g., first, second, third). For most numbers, this rule applies universally, including 90.
For example, if we want to talk about the position of the number 90 in a sequence, we would say “90th” without any hesitation. Imagine a race, and you are counting the runners as they cross the finish line. When the 90th runner completes the race, you would say, “The 90th runner has finished.” Here, “90th” clearly indicates the runner’s position in the race.
Now, let’s consider why “90nd” is incorrect. The suffix “-nd” does not exist in the English language to form ordinal numbers. This suffix is not recognized in any English grammar rules or dictionaries, making it invalid and non-standard. It may appear like a logical extension based on the pattern observed in numbers ending in “-nd” such as “2nd,” “22nd,” or “32nd.” However, this pattern does not extend to numbers like 90.
To further emphasize the incorrectness of “90nd,” let’s analyze another example. Suppose you are organizing a trivia quiz where participants need to answer questions related to historical events. If one of the questions asks for the year when World War II ended, the correct answer would be “1945” alone. However, if the question asks for the ordinal form of that year, we would say “1945th” to indicate the position of that year in the historical timeline. It would be erroneous to say “1945nd” because it violates the established rules of English grammar.
In summary, the correct ordinal form for 90 is “90th.” The use of “90nd” is incorrect because it does not conform to the grammar rules of English. When discussing the position or order of 90 in a sequence, make sure to use the appropriate ordinal form to ensure clarity and accuracy in your communication.
I often encounter students who struggle with the proper use of ordinals. By understanding and applying the correct grammar rules, you can enhance your English language skills and improve your overall performance in tests like IELTS. Remember, mastering the fundamentals of grammar will not only help you communicate effectively but also enhance your language proficiency in various domains.
