'Banana' refers to an apparent partial reduplication of words, as in
English 'banana'. I've seen this substrate attributed to the
language of the Ubaid culture that preceded the Sumerian culture. I
wish I could tell you more about it. I'm only quoting what I
believe I've seen on Cybalist, Nostratic or Nostratica, but the only
bananas turned up by an archive searches were edible bananas.
