These two words are pronounced exactly the same, spelled almost the same, and confused constantly — even by careful writers. The difference comes down to a single letter: a versus e.
Stationary (with an a) means not moving, fixed in place.
Stationery (with an e) means writing materials — paper, envelopes, pens, notebooks.
They are not variants of each other. They are completely separate words with separate meanings. Using one when you mean the other is always an error.
Stationary — Still, Fixed, Not Moving
Stationary is an adjective. It describes something that stays in one place or does not change.
Examples:
- The car remained stationary at the intersection.
- A stationary bike lets you exercise without going anywhere.
- The storm system stayed stationary over the coast for three days.
- Prices have been stationary for several months — no increase, no decrease.
Notice it answers the question how is something? — motionless, unchanging, fixed.
Stationery — Paper, Envelopes, Writing Supplies
Stationery is a noun. It refers to writing materials, often including paper, envelopes, cards, and related supplies. It can also mean personalized or branded writing paper used for letters.
Examples:
- She ordered stationery with her name printed at the top.
- The office ran out of stationery — no paper, no envelopes, nothing to write on.
- He found a beautiful set of stationery at the gift shop.
- The school’s stationery list included notebooks, pencils, and folders.
Why These Two Words Get Confused
Both come from Latin and passed through Old French into English. They look nearly identical and sound exactly alike — what linguists call homophones.
Stationary traces back to the Latin stationarius, meaning “of a military post” — something fixed in position.
Stationery comes from stationer, a word for a shopkeeper who sold books and writing materials from a fixed stall or shop. The shop didn’t move — and neither did the seller. Over time, the goods sold by a stationer became known as stationery.
So ironically, both words share the idea of staying in one place — but they diverged into completely different meanings in modern English.
How to Remember the Difference
The most reliable trick: e for envelope.
StationEry contains an e — and so does envelope. If you’re thinking about paper and envelopes, you want the e spelling.
StationAry contains an a — and so does stAnd still. If something isn’t moving, use the a spelling.
Another angle: think of stationer — a person who sells writing supplies. Stationery is what a stationer sells.

Common Mistake to Watch For
Writers sometimes spell stationery as stationary when writing about office supplies or school materials. This is the more common direction of the error — probably because stationary is the more frequently seen word overall.
✗ Please restock the stationary cupboard.
✓ Please restock the stationery cupboard.
The cupboard holds paper and pens — writing supplies — so the e spelling is correct.
The short version: If it moves (or doesn’t move), use stationary. If you can write on it or mail it, use stationery. When in doubt, remember the envelope.
