Amis and Puyuma are two languages of eastern Formosa. In Blust’s Austronesian subgrouping (Blust 1999) they belong to different primary branches of the AN family: Amis to his East Formosan branch, along with Siraya (a west coast language), and the north Formosan languages Kavalan, Basay and Trobiawan; while Puyuma forms a branch unto itself. The ground for Blust’s East Formosan is the alleged change of PAN *j, construed as a voiced palatalized velar stop, to *n. East Formosan requires at least one prehistoric migration. The phylogenetic study of Gray et al. finds no support at all for Blust’s East Formosan. Sagart (2004, 2015) argues that the PAN phoneme known as *j was a nasal so that the modern nasal reflexes are in fact a retention—which explains their discontinuous geographic distribution at the periphery of Taiwan. It is the nonnasal reflexes which are innovative—which fits well with their continuous geographical distribution in Taiwan.
My phylogenetic scheme is based on the nested distribution of numerals 5-10 in Taiwan (Sagart 2008, modified from Sagart 2004). In it, both Amis and Puyuma are Puluqish languages. Puluqish includes all Austronesian languages where the word for ‘10’ reflects *puluq. This subgroup also includes Paiwan, and, outside of Taiwan, Malayo-Polynesian and Kra-Dai. Within Puluqish, there is evidence that Amis and Puyuma subgroup together, forming a northern group opposite Paiwan, MP and KD. Here are seven lexical innovations uniquely shared (afaik) by the two northern puluqish languages. The first three concern the numeral system.
- ‘one’ *sasay: Amis cacay ‘one’, Puyuma sasaya (< *sasay-a) ‘one’ (counting things). These forms reflect PAN *sa, short form of PAN *isa/esa ‘one’, reduplicated, plus intrusive -y- inserted beween final -a in the word-base and the linker -a- following it. Thus Puyuma has ɖaɖua-ya ‘two’, iwaiwa-ya ‘nine’, but ta-taɭu-a ‘three’, pitu-pitu-a ‘seven’, waɭu-waɭu-a ‘eight’ (all counting things);
- ‘ten’ *puluq. By the etymology proposed here, a word *puluq meaning ‘to put aside’ was recruited in counting numbers above 10 in Proto-Puluqish; *puluq ‘(n) [sets of 10] put aside’ could only arise preceded and followed by a numeral. In numbers 11 to 19, the numeral for ‘one’ probably had the shape *sa-, as still in the other Puluqish languages: Paiwan tapuluʔ < *sa-puluq and PMP *sa-puluq. Once *puluq ‘put aside’ was lost as an independent morpheme, *puluq could be reanalyzed as a morpheme meaning ‘ten’ and *sa- could be dispensed with. That reduction had taken place in the ancestor of Amis and Puyuma, but not elsewhere in Puluqish.
- ‘ten’ *mukeCep. In both languages, inherited *puluq is attested only as the serial-counting word for ‘ten’ and multiples of ten. When counting human and non-human referents, it has given way to an innovated form *mukeCep: Amis moketep, Puyuma mukʈəp. The expression of numerals 11 to 19 is complex and will not be discussed here.
- ‘bone’ *ukak: Amis ‘okak ‘bone’, Puyuma ukak ‘bone’;
- ‘cloud’ *kuCem ‘cloud’: Amis kotem ‘black cloud’, Puyuma kuʈəm ‘(big black) cloud’ (mi-a-kuʈəm ‘big black clouds promising rain’);
- ‘activity, skill *Nemak: Amis dmak ‘an activity, a happening; the things one does; to move’ (Fey); ‘activity, affair, business; to move; situation’ (Namoh); Puyuma lemak ‘know-how; skill’.
- ‘hat’ *kabuŋ: Amis kafoŋ ‘hat; anything worn on the head’ (Fey); Puyuma kabuŋ ‘hat’, mi-kabuŋ ‘wear a hat’ (Cauquelin).
