(jump up one level to Walu-Siwaish)
The West-coast Walu-Siwaish languages are Papora and Hoanya, two extinct languages, each of them significantly diverse. Their last speakers were interviewed mainly by Japanese linguists in the late 19th and early 20th centuries. We possess short vocabularies for a number of locations in rough phonetic transcriptions. Tsuchida (1982) includes a collection of these forms, now in part accessible online through the Hoanya and Papora pages of the Austronesian Basic Vocabulary Database (ABVD; here and here) of Greenhill et al. (2003-).
Tsuchida (1982) gave two shared lexical innovations of Papora and Hoanya (i.e., Proto-Western Walu-Siwaish): [*S]iu ‘salt’ and *mari ‘sour’. We may add one lexical innovation, relating to the word for ‘fire’.
A correspondence between Hoanya and Papora voiced coronals recurs over these comparisons, which include ‘fire’ and ‘black’. First I should clarify some Papora-Hoanya correspondences.
|Hoanya #1-1a||Hoanya #1-8||Papora #1-3||Papora #2|
‘Fire’. Blust’s Austronesian Comparative Dictionary (ACD; here) assigns the Hoanya and Papora words for ‘fire’ to PANBlust *Sapuy ‘fire’. In their Austronesian Basic Vocabulary Database (ABVD), Greenhill et al. (2003-), do the same, listing the forms under cognate set #1 (here). However this will not do, since Blust’s PAN *S goes to s- in Hoanya (*Sikan ‘fish’ > sikan, *Suaji ‘younger sibling’ > suazi, *Sepat ‘4’ > supat) and in Papora as well (*Siwa ‘nine’ > siya, *daqiS ‘forehead’ > ddes). Conversely none of the other Hoanya-Papora words with the same correspondence as ‘fire’ (see the above table) goes back to PAN *S. Either there has been an irregular sound change turning PAN *S into some voiced coronal in the Papora-Hoanya word for ‘fire’, or, more plausibly, the Hoanya and Papora forms for ‘fire’ are cognates of another word: PMPBlust *dapuR ‘hearth’, even though this last form has not hitherto been observed in Formosan languages. Tsuchida (1969) reconstructs *Z in ‘rain’ (*qu2ZaN), one of the words which exemplify the Papora-Hoanya correspondence (above table). This is the same phoneme as Blust’s * z and Ross’s *z. I take it to be an affricate and will write PWS *dzapuR, *abidzu. Taking a hint from Wolff (2010) I gloss the form as ‘cooking fire’. The best solution is to assume that *dzapuR displaced Blust’s *Sapuy as ‘fire’ exclusively in western Walu-Siwaish. For the final consonant, Papora-Hoanya examples of PAN final *-R are few, but *-R falls in Hoanya #1-1b matulu ‘to sleep’ < *ma-tuduR (this etymon is not found elsewhere in Papora or Hoanya).
