Mad-apple
From our UK edition
In the warm weather, I had an al fresco hit with my mad-apple bruschette. Mad-apple shows the tangle to which ‘a foreign and unintelligible word is liable under the influence of popular etymology’. It is a name for the aubergine, or egg-plant as it was earlier known in England, as it still is in America. Why mad-apple? Because the Renaissance Latin name was malum insanum, from the lost Italian form mela insana. This was a rationalisation of the earlier melanzana, attested in Sicilian use by the Arab geographer Idrisi in the 12th century. There it was a straight borrowing from the Greek melintzana, earlier matizanion, adapted from the Arabic badinjan.
