Mid 17th century: from French désorienter 'turn from the east'.

• Orient from Late Middle English:

  Since the Middle Ages the countries of the East have been referred to as the Orient—the first recorded use of the term appears in Geoffrey Chaucer's Canterbury Tales. The name goes back to Latin oriri ‘to rise’, also the source of original (Late Middle English) and refers to the rising of the sun. The opposite is Occident, a name for the countries of the West which comes from Latin occidere ‘to go down, set’, and refers to the setting of the sun. The English football club Orient (later known as Clapton Orient, and now as Leyton Orient) was founded in 1881. The name was suggested by a player who worked for the Orient shipping line, and was appropriate, as the club is based in the East End of London. Disorient (mid 17th century) was originally ‘to turn from the east’.
