stationery n.

"book-dealer, seller of books and paper," early 14c. (late 13c. as a surname), stacioner, from Medieval Latin stationarius "tradesman who sells from a 'station' or shop," from an adjective stationarius "not moving" (see stationary), or else an agent noun from station (n.). In the Middle English period, roving peddlers sold goods and wares; the sellers with fixed locations often were bookshops licensed by the universities; hence the word acquired a more specific sense.

noun suffix, in army, city, country, etc., from Old French -e, Latin -atus, -atum, past participle suffix of certain verbs, which in French came to be used to indicate "employment, office, dignity" (as in duché, clergié).

late 14c., stacionarie, "having no apparent motion" (in reference to planets), via Anglo-Latin stationarius "motionless," from the stem of statio "a standing, post, job, position" (see station (n.)). The Old French form was stacioonaire. The meaning "unmovable" is from 1620s. In classical Latin, stationarius is recorded only in the sense "of a military station;" the word for "stationary, steady" being statarius.
