Blench (2019)[4] groups the following in the (Central) Ron/Run dialect cluster: Bokkos, Mbar, Daffo–Butura, Manguna, Mangar, Sha.
While noting that Ron is in fact a complex linkage, Blench (2003) rejects two of the connections proposed in Seibert (1998) [Sha with Mundat–Karfa and Mangar with Kulere/Richa]:[5]
Since the Ron languages form a diverse linkage, Ron reconstruction is not straightforward due to the lack of neat sound correspondences. There are many borrowings from neighbouring Niger-Congo Plateau languages that Ron had assimilated or been in contact with.[3]
Proto-Ron reconstructions by Roger Blench are as follows.[2]
