kiosk (n.)
A kiosk is a small stall you buy something at, or a screen you touch to print a ticket. It came into English through the French kiosque, from the Turkish köşk, and behind that the Persian kūshk.1
A köşk was a pavilion, open on some or all sides, built in a garden to be sat in. The Çinili Köşk at Topkapı, put up in 1472 under Mehmed II, was a pleasure pavilion in the outer gardens, used to watch the games and spectacles held in the square it faced.2
Europe borrowed the building first, in the seventeenth century, as ornament for parks and gardens. Then the word was handed down to smaller and smaller things: a newspaper stand by the 1860s, a telephone box in the 1920s, and now a machine bolted to the floor of an airport.1
