Notes: Correspondences are regular. There may have been a vowel variation (or Ablaut) *-eƛu / *-uƛV - to account for the PA form *ʔan-ƛV- < *han-uƛV- (although actually the -u-vowel is reflected only in Cham., and the forms of other languages may reflect a protoform with other vowels). A continuation of the same stem (cf. its PA shape *ʔan-ƛV-), with a further addition of an expressive preverb *č̣-, may be PTsKh *č̣aʎ- (~-L-) > Tsez. č̣aʎ-, Gin. c̣aʎ- 'to hear, understand'.
