banana: [16] Banana comes from a West African language – possibly Wolof, a language of the Niger-Congo family, spoken in Senegal and the Gambia. The original European discoverers of the word – and the fruit – were the Spanish and Portuguese, who passed them on to England. The term bananas ‘mad’ is 20th-century, but its origins are obscure; some have compared banana oil, a 20th-century slang term for ‘mad talk, nonsense’.
