When it comes to ordinal numbers, it can be confusing to determine whether to use “50th” or “50rd.” However, the correct form to use is “50th.” Allow me to explain why and provide you with some examples to demonstrate this.
In English, we use ordinal numbers to indicate the position or order of something in a sequence. These numbers generally end with the letters “th,” “st,” “nd,” or “rd.” While “th” is the most common suffix used for ordinal numbers, “st,” “nd,” and “rd” are only used for the numbers 1, 2, and 3, respectively.
Now, let’s take a closer look at the number 50. Since it is greater than 3, we use the general rule and add “th” to form the ordinal number “50th.” Here are some examples to illustrate this:
1. She finished in 50th place in the race.
2. He received the 50th edition of the magazine.
3. This is the 50th anniversary of their wedding.
In each of these sentences, the ordinal number “50th” is used to indicate the position or order of something. It is important to note that we never use “50rd” because “rd” is only used with the number 3, not 50.
To further clarify, let’s consider the difference between the two forms using a metaphor. Imagine a marathon race where each runner is given a numbered bib to wear. Now, if you were the 50th runner to register, would you proudly display your bib with the number “50rd” on it? Of course not! It would be incorrect and confusing to use “50rd” because it goes against the established rules of ordinal numbers.
In addition to the metaphor, let me ask you a rhetorical question. If someone were to tell you that they are attending their friend’s 50rd birthday party, would you think that sounds correct? Most likely not, as it would sound strange and unfamiliar. Instead, we would naturally expect them to say “50th birthday party” because that is the correct form.
In conclusion, the correct form to use when referring to the 50th position or order is “50th.” While it may seem tempting to use “50rd” due to the presence of the number 3, this would be incorrect. By following the established rules of ordinal numbers, we can communicate effectively and avoid confusion. So remember, whether it’s a race, anniversary, or birthday party, always use “50th” to indicate the position or order in a sequence.
