22th or 22nd: Quick Answer
The correct spelling is 22nd. The form 22th does not exist in standard English and is considered a spelling error in every context, whether you are writing a birthday message, a business email, or a school assignment. Whenever you are unsure between 22nd or 22th, remember that only one of them appears in dictionaries, style guides, and edited publications.
Simple Rule
Ordinal numbers change their ending based on the final digit of the number.
- Numbers ending in 1 usually take st (like 21st)
- Numbers ending in 2 usually take nd (like 22nd)
- Numbers ending in 3 usually take rd (like 23rd)
- Most other numbers take th (like 24th, 25th, 30th)
Since 22 ends in the digit 2, it follows the nd pattern, which is exactly why 22nd or 22th resolves in favor of 22nd every time.
The Origin of 22th or 22nd
Ordinal numbers in English developed from older number forms where certain endings marked position rather than quantity. Over time, the language settled into the pattern used today, where 1, 2, and 3 keep special suffixes while most other numbers default to th. This history explains why questions like 22nd or 22th keep coming up, since the brain naturally expects every number to end in th.

22nd or 22th birthday
Birthdays are one of the most common places this mix up appears. A message like happy 22th birthday looks careless, while happy 22nd birthday reads correctly and professionally. If you are writing a birthday card, a social media caption, or an invitation, the safe and grammatically sound choice is always 22nd, since 22th simply is not a recognized word.
Common Mistakes with 22th or 22nd
Even confident writers slip up here because the mistake feels natural. Understanding the pattern behind 22nd or 22th helps you catch the error before it reaches your reader.
Common Errors and Fixes
- Writing 22th instead of 22nd
- Applying th without checking the last digit
- Copying an autocorrect typo unnoticed
- Confusing 22nd with exceptions like 12th
Incorrect Example
She turned 22th years old last week.
Correct Example
She turned 22nd years old last week, or more naturally, she turned twenty two last week and celebrated her 22nd birthday.
Why the Mistake Happens
Most ordinal numbers people use daily, such as 4th, 9th, and 10th, already end in th, so the brain treats th as a default setting. When 22 comes along, that habit gets applied without a second thought, even though the rule is different. Fast typing and autocorrect also introduce this error, which is part of why 22nd or 22th remains a frequently searched question.
Easy Rule for Ordinal Numbers
Look only at the last digit of the number to decide the suffix.
- Ends in 1, use st, except for 11
- Ends in 2, use nd, except for 12
- Ends in 3, use rd, except for 13
- Ends in anything else, use th
Since 22 ends in 2 and is not part of the 12 exception, 22nd or 22th is settled firmly in favor of 22nd.
Exceptions
The numbers 11th, 12th, and 13th always use th, even though they end in 1, 2, and 3. This is the only real exception in the entire ordinal number system, and it does not affect 22, 32, 42, or any other number ending in 2 outside the teens.
