Coca-Cola

South American plant, 1570s, from Spanish coca, from Quechua (Inca) cuca, which is perhaps ultimately from the related Aymara, a native language of Bolivia.

1795, genus of small evergreen trees native to west Africa, introduced and nativized in New World tropics, from a Latinized form of a West African name of the tree (compare Temne kola, Mandingo kolo). The cola-nut contains much caffeine.

Meaning "carbonated soft drink" is 1919, short for Coca-Cola, Pepsi-Cola, and their many imitators. A 1900 publication ("Alcohol," by the Woman's Christian Temperance Union) lists the names of drinks found to contain caffeine and extract of coca leaf:

Afri Cola, Ala Cola, Cafe Coca, Carre Cola, Celery Cola, Chan Ola, Chera Cola, Coca Beta, Coca Cola, Pilsbury's Coke, Cola Coke, Cream Cola, Dope, Four Kola, Hayo Kola, Heck's Cola, Kaye Ola, Koca Nola, Koke, Kola Ade, Kola Kola, Kola Phos, Koloko, Kos Kola, Lime Cola, Lima Ola, Mellow Nip, Nerv Ola, Revive Ola, Rocola, Rye Ola, Standard Cola, Toka Tona, Tokola, Vim-O, French Wine of Coca, Wise Ola.

soft drink, 1909, a popular shortening of the brand name Coca-Cola, perhaps influenced by the earlier slang use of coke for cocaine (another popular early name for the soft drink was dope).
