Ordinal numbers are a crucial aspect of English grammar, yet they can often lead to confusion.
One common mistake involves writing “24rd” instead of the correct “24th.”
This article will clarify why “24th” is the proper form, explain the rules behind ordinal numbers, and provide tips to avoid such errors in the future.
“24th” is correct because numbers ending in 4 use the “-th” suffix.
Let’s dive deep into the fascinating world of ordinals and ensure you never mix them up again.
Understanding “24th”: The Correct Form
“24th” is the accurate ordinal form of the number 24, used to denote position or sequence. It’s derived from the word “twenty-fourth,” where the suffix “-th” is added to indicate order.
Why is “24th” Correct?
English ordinal numbers follow specific rules when determining suffixes:
- For numbers ending in 4 (except for exceptions like 11-13), the suffix “-th” is used.
- The base word “twenty-four” ends with “four,” requiring the addition of “-th” to form “twenty-fourth.”
Examples of “24th” in Use
- Dates: “The event is scheduled for May 24th.”
- Milestones: “This is the company’s 24th anniversary.”
- Achievements: “She ranked 24th in the national competition.”
These examples demonstrate the versatility and correct usage of “24th” in both written and spoken English.
Incorrect Forms: Common Mistakes with 24rd, 24st, and 24nd
24rd
“24rd” is incorrect because the suffix “-rd” only applies to numbers ending in 3 (e.g., 3rd, 23rd, 33rd). Since “twenty-four” ends with 4, using “-rd” is a grammatical error.
Why Does This Mistake Happen?
- Typographical errors or auto-correct functions may replace “th” with “rd.”
- A lack of familiarity with ordinal rules can also lead to this confusion.
Examples of Misuse
- Incorrect: “The meeting is on May 24rd.”
- Correct: “The meeting is on May 24th.”
24st
The suffix “-st” is exclusively for numbers ending in 1, such as 1st, 21st, or 31st. Using “24st” is incorrect because 24 doesn’t end with 1.
Common Causes of the Error
- Misunderstanding ordinal number patterns.
- Mistakenly applying rules for 21st to other numbers.
Examples of Misuse
- Incorrect: “This is her 24st attempt.”
- Correct: “This is her 24th attempt.”
24nd
The suffix “-nd” applies only to numbers ending in 2, such as 2nd, 22nd, or 32nd. “24nd” is not valid because the number 24 ends in 4.
Why It’s Incorrect
- Overgeneralizing the rule for “-nd” to numbers beyond those ending in 2.
- Careless typing or lack of proofreading.
Examples of Misuse
- Incorrect: “She finished in 24nd place.”
- Correct: “She finished in 24th place.”
Comprehensive Overview of Ordinal Number Rules
Understanding the broader framework of ordinal numbers helps eliminate errors.
Suffix Rules for Ordinals
| Number Ending | Correct Suffix | Examples |
|---|---|---|
| 1 | -st | 1st, 21st, 31st |
| 2 | -nd | 2nd, 22nd, 32nd |
| 3 | -rd | 3rd, 23rd, 33rd |
| 4–9, 0 | -th | 4th, 24th, 30th, 100th |
Exceptions
- Numbers 11, 12, and 13 always take “-th,” even though they end with 1, 2, or 3.
- Examples: 11th (eleventh), 12th (twelfth), 13th (thirteenth).
Ordinal Numbers in Everyday Use
- Dates: “The workshop is on January 24th.”
- Rankings: “He finished 24th in the marathon.”
- Events: “This marks their 24th year in business.”

Fun Facts About Ordinal Numbers
- Origins: The word “ordinal” comes from the Latin “ordinalis,” meaning “denoting order.”
