  ::I've never heard of alphabetical order (Indo-European, Niger-Congo, Uto-Aztecan, Oto-Mangean, etc. etc.), and all the refs I've found have the M-K order. ::Per your comment, I've deleted Malvi.  It's listed as a dialect in the Konkani article.  (I'm assuming some varieties are obviously dialects of one or the other, and that it's the more divergent cases that are debatable.) —
