The Northern Formosan languages is a proposed grouping of Formosan languages that includes the Atayalic languages, the Western Plains languages (Papora, Hoanya, Babuza, and Taokas), and the Northwest Formosan languages (Pazeh and Saisiyat; Li places Western Plains with this grouping).
The Northern Formosan subgroup was first proposed by Paul Jen-kuei Li in 1985.[1]Blust (1999) rejects the unity of the proposed Northern Formosan branch. A 2008 analysis of the Austronesian Basic Vocabulary Database, however, supports the unity of the Northern Formosan branch with a 97% confidence level (see Austronesian languages#Classification).
Evidence
The following sound changes from Proto-Austronesian occurred in the Northern Formosan languages (Li 2008:215).[2]
The four coastal languages of Taokas, Babuza, Papora, and Hoanya share the following innovations (Li 2003).
Loss of *k
Loss of *-y
Merger of *s and *t in non-final position
Complete merger of *ŋ and *n
Thao shares the following innovations with the four coastal languages (Li 2003).
Merger of *s and *t
Merger of *ŋ and *n
Pazih has undergone the following two sound changes.
Merger of *j and *s as /z/
Merger of *C and *S1 as /s/
Li (2003) does not consider Pazih to be very closely related to Saisiyat (Li 2003:946).
However, Shibata (2022) argues that the "Western Plains" languages in fact form a convergence area or linguistic area rather than a true subgroup.[4]
