ORANGE Or"ange, n. Etym: [F.; cf. It. arancia, arancio, LL. arangia, Sp. naranjia, Pg. laranja; all fr. Ar. naranj, Per. naranj, narang; cf. Skr. naranga orange tree. The o- in F. orange is due to confusion with or gold, L. aurum, because the orange resembles gold in color.]

1. The fruit of a tree of the genus Citrus (C. Aurantium). It is usually round, and consists of pulpy carpels, commonly ten in number, inclosed in a leathery rind, which is easily separable, and is reddish yellow when ripe.

Note: There are numerous varieties of oranges; as, the bitter orange, which is supposed to be the original stock; the navel orange, which has the rudiment of a second orange imbedded in the top of the fruit; the blood orange, with a reddish juice; and the horned orange, in which the carpels are partly separated.
