Comments: Min dialects have not preserved the word, but the clearly related 往 *waŋʔ 'to go' has Min reflexes: Xiamen ɔŋ3, Chaozhou uaŋ3, Fuzhou uoŋ3, allowing to reconstruct *w- (not *wh-) [the reconstruction in RDFS p. 158 is incorrect - as well as the observation on the previous page that only OC *wh- can go back to ST *ʔʷ - the problem needs further investigation].
Also used as an interjection (especially in the combination 于嗟 *wa-ciaj).
