Whereas eggplant was coined in English, most of the diverse other European names for the plant derive from the Arabic: باذنجان bāḏinjān. Bāḏinjān is itself a loan-word in Arabic, whose earliest traceable origins lie in the Dravidian languages. The Hobson-Jobson dictionary comments that “probably there is no word of the kind which has undergone such extraordinary variety of modifications, whilst retaining the same meaning, as this”.
