Proto-Malayo-Polynesian language

Proto-Malayo-Polynesian (PMP) is the reconstructed ancestor of the Malayo-Polynesian languages, which is by far the largest branch (by current speakers) of the Austronesian language family. Proto-Malayo-Polynesian is ancestral to all Austronesian languages spoken outside Taiwan, as well as the Yami language on Taiwan's Orchid Island. The first systematic reconstruction of Proto-Austronesian ("Uraustronesisch") by Otto Dempwolff was based on evidence from languages outside of Taiwan, and was therefore actually the first reconstruction of what is now known as Proto-Malayo-Polynesian.
