Dictionary.com's Word of the Year is...
c.1300, of the fruit, from Old French orange, orenge (12c., Modern French orange), from Medieval Latin pomum de orenge, from Italian arancia, originally narancia (Venetian naranza), alteration of Arabic naranj, from Persian narang, from Sanskrit naranga-s "orange tree," of uncertain origin. Not used as a color word until 1540s.
Loss of initial n- probably due to confusion with definite article (e.g. une narange, una narancia), but perhaps influenced by French or "gold." The name of the town of Orange in France (see Orangemen) perhaps was deformed by the name of the fruit. Orange juice is attested from 1723.
The tree's original range probably was northern India. The Persian orange, grown widely in southern Europe after its introduction in Italy 11c., was bitter; sweet oranges were brought to Europe 15c. from India by Portuguese traders and quickly displaced the bitter variety, but only Modern Greek still seems to distinguish the bitter (nerantzi) from the sweet (portokali "Portuguese") orange. Portuguese, Spanish, Arab, and Dutch sailors planted citrus trees along trade routes to prevent scurvy. On his second voyage in 1493, Christopher Columbus brought the seeds of oranges, lemons and citrons to Haiti and the Caribbean. Introduced in Florida (along with lemons) in 1513 by Spanish explorer Juan Ponce de Leon. Introduced to Hawaii 1792.
city, east-central New South Wales, Australia. It is located near the slopes of Mount Canobolas, an extinct volcano. In 1828 the area was named by Sir Thomas Mitchell in memory of the Prince of Orange, his commander during the Peninsular War, and the village of Orange was proclaimed in 1846. It grew after the announcement in 1851 of payable gold deposits at nearby Ophir. Farming replaced mining, and Orange is now the centre of a fruit-growing (mainly apples), mixed-farming, and grazing area. It has stockyards and abattoirs, and light-industrial development includes the manufacture of electrical appliances. It was proclaimed a town in 1885 and a city in 1946. In 1972 it was proclaimed part of the Bathurst-Orange Growth Area, designed to promote decentralization. Orange is noted for its parks and its October cherry blossom festival. Pop. (2006) local government area, 35,339.
