Pyjamas or Pajamas? Here's the Answer (And Why It Doesn't Really Matter)

One spelling. Two versions. Zero agreement.

If you've ever second-guessed yourself typing "pyjamas" or "pajamas," you're not alone. It's one of those words that looks wrong no matter which way you write it. So let's settle this once and for all.

Where Did the Word Even Come From?

Both spellings trace back to the Persian word "pāyjāmeh" meaning leg garment. It described loose, lightweight trousers worn across South Asia — practical, breathable and comfortable for the climate.

The British adopted the word during the colonisation of India and brought it home with them. By the 19th century, pyjamas had made their way into Western bedrooms and never left. The British kept the 'y' giving us pyjamas. When the word crossed to America it became pajamas, following the American habit of simplifying British spellings. Think colour vs color, favourite vs favorite.

If you want to go deeper into the full history of how pyjamas evolved from practical daywear to the sleepwear we know and love today, Cozy Earth has a great read on exactly that.

So neither spelling is wrong. They're just different sides of the same very comfortable coin.

Who Says What?

In Australia, the UK and most Commonwealth countries it's pyjamas with a 'y'. In the US, Canada and much of the rest of the world  it's pajamas with an 'a'.

Here at Kip & Boo we're proudly Australian, so it's pyjamas all the way. Although if you searched "pajamas" and landed here welcome, we're glad you found us.

What About Nightie vs Nightgown?

While we're on the subject of sleepwear words that mean the same thing spelled differently nightie and nightgown follow a similar pattern.

Nightie is the casual, friendly Australian term. Nightgown is more formal and more commonly used in the US and UK. Same garment, different flavour.

At Kip & Boo we say nightie, always. Because it sounds like something you'd actually want to wear, rather than something your great grandmother kept folded in a cedar chest.

Is it Pyjama or Pyjamas?

Both are correct depending on context. Pyjama refers to a single garment as in a pyjama top or pyjama pants. Pyjamas (plural) refers to the full set. You'd say "I love these pyjamas" but "where's my pyjama top?"

Same rule applies to pajama and pajamas in American English.

So Which Spelling Does Google Prefer?

Neither Google is smart enough to understand that pyjamas and pajamas mean the same thing. If you search either spelling you'll get the same results. Which is why you'll notice we use both naturally throughout this site.

Does Any of This Affect What You Actually Wear?

Not even slightly. What actually matters is the fabric.

Cotton can trap heat and leave you waking up sweaty at 3am. Synthetic fabrics don't breathe. Silk is beautiful but needs careful handling and a generous budget.

Bamboo viscose is the one that changes everything. Naturally breathable, temperature regulating and impossibly soft it's the fabric that makes you wonder why you ever wore anything else to bed. Our OEKO-TEX certified bamboo pyjamas are designed for Australian women who take their sleep seriously and their slow mornings even more so.

Breathable enough for warm Australian nights. Soft enough to never want to take off. Whether you're a pyjamas person or a pajamas person — bamboo works either way.

FAQ: Pyjamas vs Pajamas

Is it pyjamas or pajamas in Australia? In Australia it's pyjamas with a 'y'. The American spelling pajamas is also widely understood but pyjamas is the standard Australian English spelling.

Which spelling is correct? Both are correct — they're regional variations of the same word. Pyjamas is used in British and Australian English. Pajamas is used in American English.

What do Australians call a nightie? A nightie! It's the casual, friendly Australian term for a sleep dress or nightgown.

Is bamboo sleepwear worth it? Yes. Bamboo viscose is naturally breathable, temperature regulating, hypoallergenic and stays soft wash after wash. Once you try it, cotton feels like a step backwards.

So Pyjamas or Pajamas — Which Are You?

Team 'y' or team 'a', the answer is the same. Great sleepwear isn't about spelling. It's about how you feel the moment you put it on.

Soft. Comfortable. Like you made a very good decision.
