22th or 22nd – Which Spelling Is Correct?

The correct spelling of the ordinal number for 22 is 22nd. The form 22th is an incorrect form and should be avoided in all formal and informal writing.
So to be clear:
- 22nd (correct ordinal form) ✅
- 22th (incorrect form) ❌
Why is this the case? Let’s look at how ordinal numbers in English work.
22th
The spelling “22th” might look like it makes sense because the number 22 ends in 2. But in English, ordinal numbers have specific suffixes that follow well-established rules.
Is 22th correct?
No. According to the grammar rules for ordinal numbers, the correct suffix for numbers ending in 2 (except 12) is “nd”. So 22th is a misspelling and an example of one of the most common suffix errors in numbers.
Let’s take a look at a scenario where someone uses this incorrect form:

22nd
22nd is the proper ordinal number usage for 22. It follows the standard English ordinal rules. The number 22 ends in the digit 2, and that takes the “nd” suffix, like 2nd, 22nd, 32nd, and 42nd.
This is how suffix for 22 works:
- 1 → 1st (first)
- 2 → 2nd (second)
- 3 → 3rd (third)
- All other digits generally take “th”, except for some irregular ordinal numbers.
Ordinal form of 22: Twenty-second
22 (cardinal form of ordinal number): 22
Written form: Twenty-Second
Examples of the correct form in real-life situations:

- September 22nd
- October 22nd
Which Is Used the Most?
Let’s look at some tools to see usage frequency.
1. Google Ngram Viewer
When you compare “22nd” and “22th” using Google Ngram Viewer, you’ll find that “22nd” dominates in usage, while “22th” barely appears. This shows that real-world English usage overwhelmingly supports the correct form.
2. Cambridge Dictionary and Merriam-Webster Dictionary
Both authoritative sources confirm that 22nd is correct. You won’t find “22th” listed as a proper form in either dictionary.
Grammar Rule for Ordinal Numbers
Here’s a quick ordinal suffix guide for numbers ending in different digits:
Ending Digit | Ordinal Suffix | Example |
---|---|---|
1 | st | 21st |
2 | nd | 22nd |
3 | rd | 23rd |
4-0 | th | 24th, 30th |
Note: Numbers ending in 11, 12, and 13 are exceptions (e.g., 11th, 12th, 13th).
So, while 2nd and 22nd use “nd,” 12th uses “th” because it’s an irregular ordinal.
This rule helps answer the question: nd or th for 22? Definitely nd.
Date Formatting and Hyphenation
When writing dates:
- It’s grammatically correct to use 22nd in both formal and casual writing.
- In most cases, hyphenation isn’t required when using numeric ordinals.
For example:
- Correct: He was born on September 22nd.
- Incorrect: He was born on September 22-th.
When writing out the number in words:
- Correct: Twenty-second
- Incorrect: Twenty-secondth
Common Spelling Mistakes with Numbers
Here are some examples of ordinal number errors people commonly make:
Incorrect Form | Correct Form | Explanation |
22th | 22nd | 22 ends in 2, so it takes “nd” |
23th | 23rd | 23 ends in 3, so it takes “rd” |
32th | 32nd | 32 ends in 2, use “nd” not “th” |
42th | 42nd | 42 ends in 2, use “nd” |
These are all common grammar mistakes. If you’re ever unsure, refer to the Merriam-Webster Dictionary or the Cambridge Dictionary.
Proper Use of Suffixes
English number suffix rules follow logic, but exceptions do exist. Here’s how to keep it straight:
- Always check the last digit of the number.
- Use “st” for 1 (except 11), “nd” for 2 (except 12), “rd” for 3 (except 13), and “th” for everything else.
Examples:
- 2 → 2nd
- 22 → 22nd
- 32 → 32nd
- 42 → 42nd
This is the English suffix usage system that governs writing numbers correctly.
