Why Are They Spelled Differently?
The spelling difference is connected to the development of the word in English and the spelling conventions that developed in different varieties of English.
The word ultimately comes from South Asian usage, related to a term referring to loose-fitting clothing worn on the legs. The word entered English during the period of British influence in South Asia.
Over time, different spelling conventions became established.
American English settled on pajamas, while British English retained pyjamas.
This is similar to many other differences between American and British spelling, such as:
- Color vs colour
- Center vs centre
- Favorite vs favourite
- Organize vs organise
The differences do not necessarily indicate different meanings.
Pajamas vs Pyjamas: Is One More Correct?
No.
Both pajamas and pyjamas are correct standard English spellings.
The important thing is consistency.
If you are writing for an American audience, use pajamas.
If you are writing for a British audience, use pyjamas.
For example, an American website might write:
Our store sells comfortable pajamas for the whole family.
A British website might write:
Our shop sells comfortable pyjamas for the whole family.
Neither version is grammatically wrong.
Pajamas vs Pyjamas in Other English-Speaking Countries
The spelling can vary depending on the English variety used in a country.
Pajamas is strongly associated with American English.
Pyjamas is traditionally associated with British English and is also common in several countries where British English has had a strong influence.
For international writing, either spelling may be understood. However, if you know your target audience, matching its preferred spelling is usually best.
Common Mistakes
Mistake 1: Thinking One Spelling Is Wrong
A common misconception is that pyjamas is a misspelling of pajamas, or vice versa.
That is incorrect.
Both are established English spellings.
Mistake 2: Mixing Regional Styles
If an article is written specifically for American readers, using pajamas throughout is generally more consistent.
For British readers, use pyjamas.
Avoid switching randomly between the two spellings in the same piece of writing.
Mistake 3: Assuming the Pronunciation Changes Completely
The spelling changes, but the pronunciation is essentially the same.
The difference is primarily written rather than a difference in meaning.
Mistake 4: Confusing Sleepwear With Daywear
Pajamas or pyjamas generally refer to clothing intended for sleeping or relaxing.
They are different from ordinary daytime clothing, although some modern sleepwear designs may also be worn casually at home.

The best spelling depends on your audience.
Use “Pajamas” if:
- You are writing in American English.
