Protoform: *=aχ- / *=aχ:-
Meaning: 1 to fall 2 to throw (down)
Avar: reχ:- 2
Chadakolob: =eχ- 1,2
Andian language: =aχ- 1
Chamalal: =aχ- 1
Tindi: =aχ- 1
Comments: The Av. and Andian forms are obviously connected, although there is an irregular correspondence Av. -χ:- : PA *-χ-. This must be explained by a variation in the position of the resonant: PA *=aχ- < *=arχV-, Av. reχ:- < *rVχ:V- (literary Avar has here a stable r-; changing prefixes in Av. Chad. must be secondary). In both cases the resonant must have been metathesized from the Auslaut position (cf. PL *ʔaχär-). The fricative *χ develops in different ways in Av.-Andian and Tsezian languages, depending on its position (after a resonant or after a vowel).
