Rukai

Language · official in 1 country

Rukai may have been the first language to split from Proto-Austronesian: Paul Jen-kuei Li dates its separation to 3,000 BCE, against 4,500 BCE for the ancestor. Its six dialects, Budai, Labuan, Maga, Mantauran, Tanan and Tona, are spoken by the Rukai people in 12 villages of Taiwan, with varying mutual intelligibility.

About Rukai

Why Rukai has no focus system

Rukai is the only Formosan language without a focus system. Analyses of the Budai dialect find a two-way split between active, marked with u- or w-, and passive, marked with ki-, and Stanley Starosta took this as a sign that Rukai was the first branch to leave the family, although Chen in 2005 challenged the dichotomy. Rukai also marks case on an accusative pattern where most Formosan languages are ergative. Ross in 2009 noted that reconstructions of Proto-Austronesian had not yet taken Rukai into account and so could not be valid for the whole family.

What the Lower Three Villages share

Maga, Tona and Mantauran together are the 'Lower Three Villages'. Mantauran stands well apart from the other dialects. Its voiced stops have turned into fricatives, b to /v/ and g to /h/. The description of Saaroa suggests the Lower Three Villages Rukai may also be Tsouic. The Budai Rukai once lived in Sanhe Village and moved to Wutai Township in the mid-1900s.

How Tanan Rukai counts its consonants

Tanan Rukai has 23 consonants and 4 vowels with a length contrast. It divides nouns into animate and inanimate instead of personal and non-personal. Contact shows in the young: under Paiwan and Chinese influence they sometimes say [z] for /ð/, and in Tanan they may merge /θ/ into /s/.
