A user suggests that this Proto-Japonic reconstruction entry be cleaned up, giving the reason: “What is this reconstruction based on? Japanese sources consistently trace this to uma (unexplained, likely from 産む(umu, “to bear, to birth”)) + ko "child". What possible mechanism could explain the required shift from -ga to -go for Japanese? And what does the initial capital "M" indicate? This is strange notation.”
Please see the discussion on Requests for cleanup(+) for more information and remove this template after the problem has been dealt with.
