Don’t confuse “stationary” and “stationery.”
“Stationary” is an adjective. It means staying in one place: Judy exercised by riding the stationary bicycle. “Stationery” is a noun. It means writing materials: Lisa’s stationery is covered with pictures of teddy bears.
To tell the difference between these words, remember that “stationary,” which is an adjective, is the word that contains the “a” instead of the “e”-and “a” stands for “adjective.”
