The Malayo-Polynesian languages are spoken by the Austronesian peoples outside of Taiwan, in the island nations of Southeast Asia (Indonesia and the Philippine Archipelago) and the Pacific Ocean, with a smaller number in continental Asia in the areas near the Malay Peninsula, with Cambodia, Vietnam and the Chinese island Hainan as the northwest geographic outlier.

Malagasy, spoken on the island of Madagascar off the eastern coast of Africa in the Indian Ocean, is the furthest western outlier.

Many languages of the Malayo-Polynesian family in insular Southeast Asia show the strong influence of Sanskrit, Tamil and Arabic, as the western part of the region has been a stronghold of Hinduism, Buddhism, and, later, Islam.

Malayo-Polynesian languages with more than five million speakers are: Indonesian, Javanese, Sundanese, Tagalog, Malagasy, Malay, Cebuano, Madurese, Ilocano, Hiligaynon, and Minangkabau.

The most influential proposal for the internal subgrouping of the Malayo-Polynesian languages was made by Robert Blust who presented several papers advocating a division into two major branches, viz.

[9] 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.
