iwa vs. siwa ‘nine’ in Puyuma

(jump up to Puluqish)

The Walu-Siwaish word for ‘nine’ is reconstructed as *Siwa with capital *S. This is expected to give iwa in Puyuma, where *S evolves to zero. As recorded by Li and Tsuchida (here), Nanwang Puyuma indeed has iwa, but Thomson 1875 gives siva for the ‘tribe at Pilam’, which is 卑南, modern Beinan, Nanwang Puyuma.  Cauquelin’s dictionary of the same dialect gives both iwa and siwa, the latter  used in serial counting. Puyuma initial s- reflects PAN (and PWS) *s.

In an insightful paper, Blust (2001) stated that Formosan languages reflect *Siwa while Malayo-Polynesian languages reflect *siwa. He argued that the irregular shift of *S to *s in ‘nine’ in PMP was motivated by the proximity of *sa-puluq ‘ten’, which begins with *s-.  The existence of siwa in Puyuma shows that the shift from *S to *s in ‘nine’ is older than PMP. If Blust’s analogical explanation is correct, then Puyuma, or an ancestor of Puyuma, must once have had *sa-puluq  for ‘ten’. This is precisely what the etymology I have recently presented for *puluq ‘ten’ implies.
