Why turkey has the same name as Turkey
"eggplant," 1794, from French aubergine, "fruit of the eggplant" (Solanum esculentum), diminutive of auberge "a kind of peach," variant of alberge, from Spanish alberchigo "apricot" [OED]. Klein derives the French word from Catalan alberginera, from Arabic al-badinjan "the eggplant," from Persian badin-gan, from Sanskrit vatin-ganah. As a color like that of the eggplant fruit, it is attested from 1895.
