"drink made from the ground and roasted seeds of a tree originally native to Arabia and Abyssinia," c. 1600, from Dutch koffie, from Turkish kahveh, from Arabic qahwah "coffee," which Arab etymologists connected with a word meaning "wine," but it is perhaps rather from the Kaffa region of Ethiopia, a home of the plant (coffee in Kaffa is called būno, which itself was borrowed into Arabic as bunn "raw coffee").
The early forms of the word in English indicate a derivation from Arabic or Turkish: chaoua (1598), cahve, kahui, etc. French café, German Kaffe are via Italian caffè.
The first coffee-house in Mecca dates to the 1510s; the beverage was in Turkey by the 1530s. It appeared in Europe c. 1515-1519 and was introduced to England by 1650. By 1675 the country had more than 3,000 coffee houses and coffee had replaced beer as a breakfast drink, but its use there declined 18c. with the introduction of cheaper tea. In the American colonies, however, the tax on tea kept coffee popular.
