What Does “Pajamas” Mean?

Is “Pajamas” Singular or Plural?
Although pajamas refers to one set of clothing, the word is conventionally treated as plural in standard English.
For example:
My pajamas are on the bed.
Not:
My pajamas are on the bed.
You can also say a pair of pajamas when referring to one complete set:
I bought a pair of pajamas yesterday.
What Does “Pyjamas” Mean?
Pyjamas have exactly the same basic meaning as pajamas. It is the standard spelling in British English and is also common in countries and regions influenced by British English.
It refers to clothing worn for sleeping or relaxing.
Examples of “Pyjamas”

- These pyjamas are made from cotton.

The spelling may look different, but the pronunciation and meaning are essentially the same.
What Is the Difference Between Pajamas and Pyjamas?
The main difference is regional spelling, not meaning.
- Pajamas are preferred in American English.
- Pyjamas are preferred in British English.
- Both spellings are grammatically correct.
- Both refer to sleepwear or clothing worn for relaxation.
- The pronunciation is generally the same.
- Neither spelling is an error when used according to the appropriate regional variety of English.

American English

British English

Both sentences are correct.
Why Are There Two Spellings?
The difference developed through the history of English and regional spelling conventions.
The word ultimately comes from a term associated with clothing worn in South and West Asia and derives from the Hindi/Urdu word pāy jāma, referring historically to leg clothing. English adopted the word and developed different spelling conventions over time.
American English commonly settled on pajamas, while British English retained pyjamas.
This is similar to other spelling differences between American and British English, such as:
- color / colour
- favorite / favourite
- center / centre
- organize / organise
- traveling / travelling
The important point is that pajamas and pyjamas are regional variants of the same word.

Common Mistakes
Mistake 1: Calling “Pyjamas” Incorrect
Some American English speakers may see pyjamas and assume it is misspelled.
Incorrect assumption:
“Pyjamas is spelled incorrectly.”
Better understanding:
“Pyjamas is the standard British English spelling.”
Mistake 2: Calling “Pajamas” Incorrect in Every Context
The opposite mistake is also common. Pajamas is not an incorrect spelling simply because British English uses pyjamas.
Correct:
I bought new pajamas.
(American English)
Mistake 3: Mixing Regional Spellings
A piece of writing can look inconsistent when it switches unnecessarily between American and British conventions.
For example:
I packed my pajamas and favourite blanket.
This combines an American spelling (pajamas) with a British spelling (favourite).
For consistent American English, write:
I packed my pajamas and favorite blanket.
For consistent British English, write:
I packed my pyjamas and my favourite blanket.
Mistake 4: Using a Singular Verb
Because pajamas refers to one set of clothing, learners sometimes use a singular verb.
Incorrect:
My pajamas are clean.
Correct:
My pajamas are clean.
Mistake 5: Assuming the Pronunciation Changes
The spelling changes from pajamas to pyjamas, but the pronunciation is generally the same.
