“22nd” is the correct ordinal form of 22. “22th” is incorrect and not used in standard English. The number 22 always takes the suffix “nd” because it ends in 2. For example: “Her birthday is on the 22nd of June.” Many people confuse ordinal number rules, but the correct form is always “22nd.”
Have you ever typed “22th” and wondered if it looked wrong? You are not alone. Many English learners and even native speakers get confused when writing ordinal numbers like 21st, 22nd, 23rd, and 24th.
The confusion happens because English number endings do not always follow one simple rule. Most numbers use “th,” so people naturally assume “22th” should also work. But English changes the ending based on the last digit of the number.
This small mistake appears in emails, invitations, school assignments, business documents, and social media posts. Using the wrong ordinal form can make writing look unprofessional or grammatically incorrect.
The good news is that the rule is actually simple once you understand it. In this guide, you will learn the correct spelling, the grammar rule behind it, common mistakes, real-life examples, and an easy trick to remember the right form every time.
By the end, you will never confuse “22th” and “22nd” again.
22th or 22nd – Quick Answer

“22th” is incorrect in English grammar.
Examples:
- My appointment is on the 22nd.
- She was born on March 22nd.
- The meeting starts on the 22nd floor.

- 22th birthday

Simple Rule
Numbers ending in:
- 1 → use st
- 2 → use nd
- 3 → use rd
- Everything else → use th
Since 22 ends in 2, it becomes 22nd.
The Origin of 22th or 22nd
Ordinal numbers have existed in English for centuries. They help show position, order, dates, and sequence.
Examples:
- First place
- Second floor
- Third chapter
- Twenty-second day
The ending “nd” in 22nd comes from the word “second.”
Here is how the pattern developed:
| Number | Word Form | Short Form |
| 1 | first | 1st |
| 2 | second | 2nd |
| 3 | third | 3rd |
| 22 | twenty-second | 22nd |
People mistakenly write “22th” because most ordinal numbers use “th,” such as:
- 4th
- 5th
- 10th
- 100th
But English keeps the “nd” ending for numbers ending in 2.
