(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, not fully systematic phonetic transcriptions. Tsuchida (1982) includes a collection of these forms, now accessible online through the Hoanya and Papora pages of the Austronesian Basic Vocabulary Database (ABVD; here and here) of Greenhill et al. (2003-).
Despite the difficulties inherent in establishing cognacy given the nature of the data, the Hoanya and Papora words for ‘fire’ and ‘black’, present us with two uniquely shared western Walu-Siwaish innovations.
A correspondence between Hoanya and Papora voiced coronals recurs over these comparisons, which include ‘fire’ and ‘black’:
|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). Allowing for the uncertainty due to the lack of cognates in other Formosan languages, I will write PWS *[Z]apuR. Taking a hint from Wolff (2010) I gloss the form as ‘cooking fire’. The best solution is to assume that *[Z]apuR 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).
‘Black’. The PAN word reconstructed by Blust as *qudem ‘black’ has a broad distribution in Taiwan; but it was displaced, exclusively in Hoanya and Papora, by a word reconstructible as *abid[z]u. There is an apparent cognate in Mongondow: mo-bidu ‘blue’, so that *abid[z]u can be assigned to PWS. However there was competition between *abid[z]u and *qudem in PWS: it is only in western Walu-Siwaish that the former diplaced the latter. In Mongondow mo-bidu has a doublet mo-biru ‘blue’. This mo-biru belongs to a widespread set which Blust (here) treats as borrowed from Malay. Although he admits that in Mongondow “it would normally be assumed that where variants in d, r appear the d variant is historically primary”, he assumes “for the present” that “Mongondow mo-bidu is a result of analogical back-formation from a loanword with r“. However, the Hoanya-Papora cognate convincingly shows that d, not r, is primary: indeed, Mongondow d is a match for Papora d, Hoanya dz, as in ‘road, path’ : Papora dalan, Hoanya dzalan, Mongondow daḷan. Only the biru-type forms are part of the loan distribution identified by Blust.
