Several scholars noted that the pronunciations of 天 “sky” tiān and 風 “wind” fēng in Bai appear to be akin to the western variants of the words attested in the paronomastic gloss dictionary Shìmíng 釋名. I will demonstrate in the current study that there are additional commonalities shared by both Bai and the ancient western dialect, termed Old Western Chinese (OWC) in this study. In both languages, one can identify words with zy- in Middle Chinese (MC) that are pronounced j-. Bai and Old Western Chinese use the same word (椹 shèn) for “fungus”. Furthermore, Old Chinese (OC) cluster *-p/t-s yields -t in both languages in lieu of yielding -j as observed in Middle Chinese. Last but not least, it appears that in both languages, words with *lˤ- (whence MC d-) and -ʔ (whence MC rising tone) are distinct from other words with d- in Middle Chinese. Hence, this paper puts the claim that Bai is akin to Old Western Chinese on a stronger footing. As a side note, judging from the fact that 四 “four” sì contains -t in Old Western Chinese and early Bai, its Old Chinese form most likely ends in *-[t]-s.

While sound glosses from the Six Dynasties and early Tang provide direct evidence for morphological alternations in Archaic Chinese, studies on the syntax of this language generally disregard these data. This neglect is due in part to perceived unreliability of these sound glosses. In this paper, I first argue that the arguments against their reliability do not stand scrutiny, and that they are not a simple philological curiosity, but have the potential to enrich studies on Archaic Chinese syntax, and plead for more collaboration between syntacticians and historical phonologists.
