Malayo-Polynesian languages
Zobel (2002) proposes a "Nuclear Malayo-Polynesian" subgroup, based on putative shared innovations in the Austronesian alignment and syntax found throughout Indonesia apart from much of Borneo and the north of Sulawesi. This subgroup comprises the languages of the Greater Sunda Islands (Malayo-Chamic, Northwest Sumatra–Barrier Islands, Lampung, Sundanese, Javanese, Madurese, Bali-Sasak-Sumbawa) and most of Sulawesi (Celebic, South Sulawesi), Palauan, Chamorro and the Central–Eastern Malayo-Polynesian languages. This hypothesis is one of the few attempts to link certain Western Malayo-Polynesian languages with the Central-Eastern Malayo-Polynesian languages in a higher intermediate subgroup, but has received little further scholarly attention.
