Comments: PA "stem I" *=ačʷ- (~ -o-) is reflected only in Tind. (=ačʷ- "to flow, spread (about the surface)"). Other languages (and also Tind.) reflect the PA "stem II" *čʷV- with suffixes (*čʷVl-, *čʷV-b-, *čʷV-r-) or the reduplicated stem *čʷVčʷV- (sometimes also with a suffix: *čʷVčʷV-b-). Besides the forms listed above cf. also: Av. čur- 'to wash', čor-dé- 'to bathe'; Cham. še-d- 'to pour, strew'; PA *=ičʷV-n- 'to wash' > Cham. =išʷVn- (Gig. =učVn-), Tind. =ičʷṼ-, Kar. =ičʷan-. Cf. also a derived noun: PA *čʷa(r)čʷa ( ~ o) 'waterfall' (Tind. čʷačʷa, Kar. čʷarčʷa, God. čorča). Cham. > Inkh. šallu 'liquid (adj.)' (quite isolated among Tsezian).
