Austronesian Languages - Classification

Classification

The internal structure of the Austronesian languages is complex. The family consists of many similar and closely related languages with large numbers of dialect continua, making it difficult to recognize boundaries between branches. However, it is clear that the greatest genealogical diversity is found among the Formosan languages of Taiwan, and the least diversity among the islands of the Pacific, supporting a dispersal of the family from Taiwan or China. The first comprehensive classification to reflect this was Dyen (1965).

The seminal article in the classification of Formosan—and, by extension, the top-level structure of Austronesian—is Blust (1999). Prominent Formosanists (linguists who specialize in Formosan languages) take issue with some of its details, but it remains the point of reference for current linguistic analyses, and is shown below. The Malayo-Polynesian languages are frequently included within Blust's Eastern Formosan branch due to their shared leveling of proto-Austronesian *t, *C to /t/ and *n, *N to /n/, their shift of *S to /h/, and vocabulary such as *lima "five" which are not attested in other Formosan languages.

There appear to have been two great migrations of Austronesian languages that quickly covered large areas, resulting in multiple local groups with little large-scale structure. The first was Malayo-Polynesian, distributed across the Philippines, Indonesia, and Melanesia. The Central Malayo-Polynesian languages are similar to each other not because of close genealogical relationships, but rather because they reflect strong substratum effects from non-Austronesian languages. The second migration was that of the Oceanic languages into Polynesia and Micronesia (Greenhill, Blust & Gray 2008).

In addition to Malayo-Polynesian, thirteen Formosan families are broadly accepted. Debate centers primarily around the relationships between these families. Of the classifications presented here, Blust (1999) links two families into a Western Plains group, two more in a Northwestern Formosan group, and three into an Eastern Formosan group, while Lee (2008) also links five families into a Northern Formosan group. The Austronesian Basic Vocabulary Database (2008) accepts Northern, rejects Eastern, links Tsouic and Rukai (two highly divergent languages), and links Malayo-Polynesian with Paiwan in a Paiwanic group. Ross (2009) splits Tsouic, and notes that Tsou, Rukai, and Puyuma fall outside of reconstructions of Proto-Austronesian.

Other studies have presented phonological evidence for a reduced Paiwanic family of Paiwanic, Puyuma, Bunun, Amis, and Malayo-Polynesian, but this is not reflected in vocabulary. The Eastern Formosan peoples Basay, Kavalan, and Amis share a homeland motif that has them coming originally from an island called Sinasay or Sanasay (Li 2004). The Amis, in particular, maintain that they came from the east, and were treated by the Puyuma, amongst whom they settled, as a subservient group (Taylor 1888).
