Pajamas or Pyjamas – Quick Answer
Quick Answer:
- American English: pajamas
- British English: pyjamas
Example Sentences:
- American English: I bought new pajamas for the winter.
- British English: She wore her pyjamas while watching TV.
In essence, both spellings are correct, but the choice depends on your audience. Using the wrong version in formal documents or publications may look unprofessional, so it’s important to pick the right one.
The Origin of Pajamas or Pyjamas
The word “pajamas” comes from the Hindi word “pāy-jāma”, which literally means “leg garment.” It was brought to English during the British colonial period in India.
Originally, pajamas referred to loose trousers tied at the waist and worn for comfort, especially in warm climates.
Over time, the term expanded to mean the full set of sleepwear, including matching tops. When the British returned from India, they brought back the word with a spelling that eventually evolved into “pyjamas”.
Americans simplified it to “pajamas”, dropping the “y,” which is common in American adaptations of British words.
So, the difference isn’t about meaning it’s about history and the influence of regional spelling conventions.
British English vs American English Spelling
The key difference lies in regional spelling rules.
| Spelling | Region | Example Usage |
| pajamas | US | I bought new pajamas yesterday. |
| pyjamas | UK, Australia, India, Canada | He spilled juice on his pyjamas. |
Rules to Remember:
- American English often simplifies spellings by removing letters that are silent or unnecessary (e.g., colour → color, theatre → theater).
- British English retains the original letters or older spellings (e.g., pyjamas, colour, theatre).
Tip: Stick to your audience. Writing for a British or Commonwealth audience? Use pyjamas. For American readers, use pajamas.
Which Spelling Should You Use?
Choosing the right spelling depends on your audience and the platform:
- For US readers: Always use pajamas. It’s standard in American media, blogs, and books.
- For UK, Australia, India, and Canada: Use pyjamas. These countries follow British spelling rules.
- For global audiences: Consider your readers. If your website or publication has more American readers, pajamas may be safer. If it’s international or Commonwealth-focused, pyjamas works best.
Professional Tip: In formal writing, consistency is key. Don’t mix spellings within the same article or document.
