"Stationery" (with E) = paper, envelopes, and writing materials; "stationary" (with A) = not moving, fixed in place.
Uncountable noun: the set of writing materials — paper, envelopes, pens, folders, paper clips, etc. Always refers to physical objects, not people or states.

The stationery store on the corner sells beautiful handmade paper and calligraphy supplies.
Wedding stationery — invitations, programs, and thank-you cards — can cost more than the flowers.
Adjective: not moving, remaining in the same place. Opposite of "moving" or "mobile". Used for stopped vehicles, stationary bikes, non-growing populations, armies in defensive position, etc.
The car remained stationary for over an hour in the tunnel during the accident.
She prefers a stationary bike for cardio because she can watch TV at the same time.
The population in that region has been stationary for decades, with births and deaths nearly equal.
Common mistake
The classic error: writing "I need some stationary" when you mean writing paper, or "the car was stationery" when describing it as not moving. The visual trick: stationERy has E for "Envelope". StationARy has A for "Automobile" (not moving). One letter difference, two completely different meanings.
Trick to remember it
Letter trick: stationERy = writing materials. The E stands for Envelope. StationARy = not moving. The A stands for stAnd still, or for an Automobile that is not moving. Another memory hook: "stationEry" has E for "pEn" (a writing tool). "stationAry" has A for "stAnd still" (to remain in place).
Quick rule
StationEry (E for Envelope) = writing materials, paper goods. StationAry (A for stAnd still) = not moving, fixed in place.
Did you know?
Both words come from the Latin "statio" (place, position). A "stationer" was originally the merchant who sold from a FIXED (stationary) stand instead of traveling from town to town. The shop where they sold was called a "stationery shop", and their products became "stationery". So curiously, "stationery" and "stationary" share the same origin — both relate to being fixed in place.
