Stationary (with an A) means not moving (a stationary vehicle). Stationery (with an E) refers to writing materials — paper, pens, envelopes.
The Core Difference
“Stationary” is an adjective describing something that is not moving or is fixed in one place: a stationary bike, stationary traffic, the object remained stationary.
“Stationery” is a noun referring to writing and office supplies — paper, envelopes, pens, notebooks: a stationery shop, office stationery. The two words are pronounced identically, so only the spelling distinguishes them.
- not moving → stationary: stationary car, stationary object
- writing supplies → stationery: stationery shop, buy some stationery

Frequently Asked Questions
What is the classic memory trick for stationary vs stationery?
Link “stationEry” with “Envelope” and “lEtter” — both share the letter E, and both relate to writing supplies. “StationAry” links to “stAy” and “pArked” — both share the letter A and describe something that does not move.
Are these two words pronounced the same?
Yes, in almost all English accents, “stationary” and “stationery” sound identical, which is exactly why the spelling distinction is so easy to forget — there is no audible clue, only the written form.
Can stationary describe a person?
Yes — “stationary” can describe a person who is standing still or not moving: “He remained stationary while the photo was taken.” It is not limited to vehicles or objects.
Is stationery always plural in meaning?
“Stationery” is a singular, uncountable noun even though it refers to a category containing many individual items (pens, paper, envelopes): “The stationery is in the top drawer”, not “the stationeries”.
What is a stationary bike?
A “stationary bike” (or exercise bike) is a piece of fitness equipment that stays fixed in one place while you pedal, as opposed to a regular bicycle that moves. It always uses the “not moving” spelling.
Why do the two words share the same root?
Both words come from the Latin “stationarius”, related to a fixed station or position. Historically, stationers were merchants who sold from a fixed shop (unlike travelling peddlers), which is how “stationery” came to mean the goods — paper and writing materials — they sold.
Is letterhead considered stationery?
Yes — letterhead, along with envelopes, business cards, and branded notepads, is a standard category of company stationery used for official correspondence.
Does autocorrect fix this mistake automatically?
No — because both “stationary” and “stationery” are correctly spelled dictionary words, standard spell-checkers will not flag an incorrect swap; you need to check the meaning of the sentence yourself.
Is a stationary object the same as a static object?
They are very similar in meaning — both describe something not moving — but “stationary” specifically emphasises the state of being fixed in place, while “static” is a broader term also used in physics, electricity, and other technical contexts.
Do exams test this spelling pair?
Yes, this is a frequently tested spelling pair in school and ESL vocabulary assessments precisely because the words are homophones with completely unrelated meanings, making the correct spelling entirely dependent on understanding context.
