Both words are correct, but they do not mean the same thing. Stationary means not moving or not changing. Stationery means paper and other writing materials.
So the right choice depends on what you mean. A parked car can be stationary. A box of letter paper is stationery.
Quick Answer
Use stationary when something is still, fixed, or not moving.
Use stationery when you mean writing paper, envelopes, cards, or related office supplies.
A simple way to remember it: stationery has e, like envelope.
Why People Confuse Them
People mix up stationary and stationery because they look almost the same. Only one letter changes: a or e.
They also sound the same in normal US English: stay-shuh-nair-ee. Because pronunciation does not help, the spelling has to come from meaning.
The mistake is easy to make in writing, especially in office, school, and business settings.

Meaning and Usage Difference
Stationary is an adjective. It describes a person, object, condition, or situation that is not moving or not changing.
Examples:
- The train remained stationary for ten minutes.
- Keep the camera stationary while recording.

Stationery is a noun. It names writing paper and related materials, such as envelopes, cards, pens, or office supplies.

- Stationery names a thing or category.
Tone, Context, and Formality
Stationary sounds a little more precise than “still” or “not moving.” It works well in reports, directions, safety notices, traffic updates, and technical writing.
In casual speech, people often say “still” instead:
- Casual: The car was still.
- More precise: The car was stationary.
Stationery is neutral. It fits everyday, school, office, retail, and event-planning contexts. It can sound slightly polished when used for nice paper, wedding cards, or business letterhead.
Neither word is slang. Neither word is mainly British or mainly American in this comparison. The choice is about meaning.
Which One Should You Use?
Choose stationary when you are describing something that does not move.
Choose stationery when you are talking about paper or writing materials.
Ask yourself this quick question:
Can I replace the word with “still” or “not moving”? If yes, use stationary.
Can I replace it with “paper,” “letter paper,” or “writing supplies”? If yes, use stationery.
When One Choice Sounds Wrong
Stationary sounds wrong when you mean paper.
Wrong: I bought new stationary for my desk.
Right: I bought new stationery for my desk.
Stationery sounds wrong when you mean still or fixed.
Wrong: The truck was stationery at the red light.
Right: The truck was stationary at the red light.
A sentence can include both words correctly:
The stationery stayed stationary on the desk when the fan was off.
That sentence is unusual, but it shows the difference clearly.
