Blust (2006) proposes that the
Sama-Bajaw languages also derive from the Barito lexical region, though not from any established group, and
Ethnologue has followed, calling the resulting group 'Greater Barito'. Smith (2017, 2018) proposes a Greater Barito linkage with the following branches, and considers
Basap to be a sister of the Greater Barito linkage, forming a
Basap–Greater Barito group. • Basap–Greater Barito •
Basap • Greater Barito • Northwest Barito (Kadorih,
Siang, Murung) • Southwest Barito (
Ngaju, Kapuas,
Bakumpai) •
Sama–Bajaw (
Yakan, etc.) • Southeast Barito (
Ma'anyan,
Dusun Witu,
Dusun Balangan,
Malagasy) • Central-East Barito (
Dusun Malang, Dusun Bayang,
Paku, Semihim) •
Northeast Barito (
Taboyan,
Lawangan, Bentian, Paser, Benuaq) •
Tunjung The earlier groupings
East Barito (comprising Smith's Southeast Barito, Central-East Barito and Northeast Barito) and
West Barito (comprising Southwest Barito and Northwest Barito) are rejected by Smith. ==West Kalimantan groups==
