Комментарии: The root occurs often with suffixed *-d- (And., Tind.: c:a- < *c̣:ad-) or *-r- (Akhv., Kar.). It may have a counterpart in Av. c̣:a-ze 'smoke, sip' (although it must be a contamination with c̣:a-ze 'pull' - which is obviously a different stem); cf. also Av. Chad. c̣uc̣ú- ( = Av. lit. c̣:ac̣:á-) 'to suck'.
