citrus: citrus: [19] Latin citrus signified the ‘citron’, a tree (Citrus medica) of Asian origin with a lemon-like fruit which was the earliest of the citrus fruits to become known in the West. Like the fruit itself, the name is presumably of Eastern origin – perhaps from a non-Indo- European language from around the eastern end of the Himalayas. Citron is a French derivative of citrus, coined on the model of French limon ‘lemon’; it was borrowed into English in the 16th century.
citrus (adj.): 1825, from Modern Latin genus name, from Latin citrus "citron tree," name of an African tree with aromatic wood and lemon-like fruit, the first citrus fruit to become available in the West. The name, like the tree, is probably of Asiatic origin [OED]. But Klein traces it to Greek kedros "cedar," and writes that the change of dr into tr shows that the word came from Greek into Latin through the medium of the Etruscans. As a noun, "tree of the genus Citrus," from 1885.
