When writing dates, rankings, birthdays, anniversaries, or numbered positions, many people wonder whether 22nd or 22th is correct. It may seem like a small grammar issue, but using the wrong ordinal number can make your writing look unprofessional and inaccurate.
If you’ve ever typed “22th birthday,” “22th anniversary,” or “June 22th” and questioned whether it was correct, you’re not alone. Thousands of English learners and even native speakers make this mistake.
In this complete grammar guide, you’ll learn the correct form, understand why it works, see practical examples, discover common mistakes, and master ordinal number rules once and for all.
What Is the Correct Form: 22nd or 22th?
The correct form is:
✅ 22nd
❌ 22th
The number 22 ends with the digit 2, and ordinal numbers ending in 2 generally use the suffix -nd.
Therefore:
- 22 → 22nd
- Twenty-two → Twenty-second
Quick Answer
| Number | Correct Ordinal | Incorrect Form |
|---|---|---|
| 22 | 22nd | 22th |
| Twenty-two | Twenty-second | Twenty-twoth |
If you’re writing a date, age, anniversary, or ranking, always use 22nd.
Featured Snippet Answer
22nd is correct because the number 22 follows the ordinal number rule for numbers ending in 2. Ordinal numbers ending in 2 use “nd,” except for numbers ending in 12, which use “th.” Therefore, 22nd is correct and 22th is incorrect.
Understanding Ordinal Numbers in English
To understand why 22nd is correct, you first need to know what ordinal numbers are.
Ordinal numbers show:
- Position
- Order
- Rank
- Sequence
Examples include:
- 1st place
- 2nd attempt
- 3rd chapter
- 22nd birthday
Unlike cardinal numbers (1, 2, 3, 22), ordinal numbers indicate where something appears in a series.
Cardinal Numbers vs Ordinal Numbers
| Cardinal Number | Ordinal Number |
|---|---|
| 1 | 1st |
| 2 | 2nd |
| 3 | 3rd |
| 4 | 4th |
| 22 | 22nd |
| 100 | 100th |
Why Ordinal Numbers Matter
Ordinal numbers appear frequently in:
- Academic writing
- Business reports
- Invitations
- Legal documents
- Emails
- Blog posts
- Event announcements
Using the wrong suffix can create grammatical errors and reduce credibility.
Examples of Correct Usage
- Today is the 22nd of June.
- She celebrated her 22nd birthday.
- The company marked its 22nd anniversary.
- He finished in 22nd place.
Why 22nd Is Correct and 22th Is Wrong
Many writers assume that because “twenty-two” ends in “two,” they should simply add “th” and write “22th.”
However, English grammar follows specific ordinal number rules.
The Rule for Numbers Ending in 2
Numbers ending in 2 generally take -nd.
Examples:
- 2nd
- 22nd
- 32nd
- 42nd
- 52nd
Because 22 ends with 2, it becomes:
22nd
Why 22th Sounds Wrong
The suffix -th is reserved for most other numbers.
Examples:
- 4th
- 5th
- 10th
- 14th
- 20th
Applying “-th” to 22 creates a form that does not exist in standard English grammar.
Written Form Comparison
| Number | Spoken Form | Correct Written Form |
|---|---|---|
| 21 | Twenty-first | 21st |
| 22 | Twenty-second | 22nd |
| 23 | Twenty-third | 23rd |
| 24 | Twenty-fourth | 24th |
Notice how 22 becomes twenty-second, not “twenty-twoth.”
Ordinal Number Rules You Must Know
Learning a few simple rules can help you avoid mistakes not only with 22nd but with every ordinal number.
Rule 1: Numbers Ending in 1 Use -st
Examples:
- 1st
- 21st
- 31st
- 101st
Rule 2: Numbers Ending in 2 Use -nd
Examples:
- 2nd
- 22nd
- 42nd
- 102nd
Rule 3: Numbers Ending in 3 Use -rd
Examples:
- 3rd
- 23rd
- 43rd
- 103rd
Rule 4: Most Other Numbers Use -th
Examples:
- 4th
- 9th
- 24th
- 50th
Important Exception: 11, 12, and 13
Despite ending in 1, 2, and 3, these numbers use -th.
Examples:
- 11th
- 12th
- 13th
This exception exists because English pronunciation follows historical language patterns.

Why These Errors Happen
Most errors occur because writers:

- Rely on autocorrect
- Learn English as a second language
Fortunately, once you remember the suffix pattern, the mistake becomes easy to avoid.
Real-Life Example: How a Small Grammar Mistake Hurt Professional Credibility
In 2025, a small event management company launched a social media campaign promoting its annual celebration. The graphics were professionally designed, the messaging was strong, and the campaign generated significant engagement.
However, one detail caught people’s attention.
The banner announced:
“Celebrating Our 22th Anniversary”
Within hours, users began commenting about the grammar mistake rather than the event itself. Several comments jokingly pointed out that “22th” does not exist in standard English.
As the discussion spread, the company had to update all promotional materials, replace printed banners, and re-upload social media graphics. While the mistake did not seriously damage the business, it shifted attention away from the event and toward an avoidable grammar error.
This example highlights an important lesson: small writing mistakes can affect credibility. Whether you’re publishing a blog post, creating marketing materials, sending emails, or writing academic content, correct grammar helps build trust.
Using the proper ordinal form 22nd instead of 22th demonstrates attention to detail and professionalism. In competitive industries, even minor language errors can influence how readers perceive your expertise.
The takeaway is simple: always verify ordinal numbers before publishing content, especially when they appear in headlines, advertisements, invitations, and official documents.
