Caraga (Karaga) Kabasagan, Boso, Mansaka, Mandayan Western Mansakan Kalagan and Tagakaolo Mamanwa Mamanwa Gallman (1997) Andrew Gallman (1997) rejects Zorc's classification of the Mansakan languages and Mamanwa as primary branches of the Central Philippine languages coordinate to the Bisayan languages. Instead, he groups Mansakan, Mamanwa and the Southern Bisayan languages together into an "East Mindanao" subgroup, which links up with the remaining Bisayan branches in a "South Central Philippine" subgroup: Tagalog Bikol South Central Philippine West Bisayan Banton Central Bisayan Cebuan East Mindanao North East Mindanao Mamanwa Surigaonon Butuanon-Tausug Central East Mindanao Kamayo Davawenyo (Banganga) Davawenyo (Digos) South East Mindanao Mandaya (Kabasagan) Mandaya (Caraga) Mansaka, Mandaya (Maragusan), Mandaya (Boso) (Branch) Mandaya (Islam) Kalagan (Kaagan), Kalagan (Tagakaulu) Greater Central Philippine (Blust) Blust (1991) notes that the central and southern Philippines has low linguistic diversity. Based on exclusively shared lexical innovations, he posits a Greater Central Philippine subgroup that puts together the Central Philippine branch with South Mangyan, Palawan, Danao, Manobo, Subanon and Gorontalo–Mongondow languages, the latter found in northern Sulawesi.
