Proto-Tsezian: *ž:ã
Meaning: horse's mane
Bezhta: žaro (Tlad.)
Gunzib: žãru
Comments: The PN paradigm must have been *ž:ã, *ž:aru-, and the PGB form *žãru can only be explained as a merger of the former direct and oblique stems - otherwise there is no way to explain the Gunz. nasalisation (impossible in PTs before -r-).
