gherkin: [17] Etymologically, a gherkin may be a ‘little unripe one’. The word was borrowed from an assumed early Dutch *gurkkijn, a diminutive form of gurk, which probably came from Lithuanian agurkas. This in turn goes back via Polish ogurek to medieval Greek angoúrion, which has been linked with classical Greek ágouros ‘youth’. [gherkin etymology, gherkin origin, 英语词源]
