What Is Pajama?
The word pajama refers to a set of comfortable clothing worn for sleeping or relaxing, usually consisting of a top and matching bottoms. This spelling is standard in American English and is widely used in the United States, Canada (in many cases), and parts of Asia influenced by U.S. English.
In modern usage, pajama appears in fashion catalogs, lifestyle blogs, medical settings (like hospital wear), and everyday conversation. When Americans talk about sleepwear, pajama is their default spelling.
How It’s Used
- As a noun: “I bought a new pajama set.”
- As an adjective: “She wore pajama pants to the store.”
Where It’s Used
- 🇺🇸 United States
- 🇵🇭 Philippines
- 🇯🇵 Japan (in English contexts)
Example Sentences
- “He changed into his pajama before going to bed.”
- “These pajama shorts are perfect for summer.”
Short History Note
The word pajama comes from the Persian word pāy-jāmeh, meaning “leg garment.” British colonists brought the term to the West, but American English later simplified the spelling by dropping the extra “y.”
When comparing pajama or pyjama, this version clearly dominates U.S.-based writing.
What Is Pyjama?
Pyjama means the exact same thing as pajama—comfortable clothing worn for sleeping—but it follows British English spelling rules. You’ll see pyjama used across the UK, Europe, Australia, and many Commonwealth countries.
Unlike American English, British English tends to preserve older or more phonetically descriptive spellings. That’s why pyjama keeps the “y,” aligning more closely with the original pronunciation.

- As an adjective: “He wore pyjama trousers.”
Where It’s Used
