Did you know?

stationary or stationery?

The Internet is awash with mnemonics (“something (such as a word, a sentence, or a song) that helps people remember something“) designed to assist those who have trouble distinguishing between two similar words. A fair share of these turn out to be for the words stationery and stationary. The most commonly suggested method is to remember that you buy papER at a stationERy store. If this trick does not work for you, then perhaps it will help to remember that a stationery store is one that is run by a stationer. This word was originally applied to a bookseller, but by the middle of the 17th century it began to be used for a person who sells papers, pens, and office goods.

Examples of stationary in a Sentence

Einstein imagined a beam of light piercing the elevator. If the elevator were rising relative to the source of light, the beam would enter at a certain height on one side of the elevator and appear to curve on its way to a lower height on the opposite wall. Einstein then imagined that the elevator were stationary on the surface of the earth. Since he postulated that the two circumstances are the same, Einstein concluded that the same effect would have to hold true for both. In other words, gravity must bend light. Smithsonian, June 2005
