Proto-West-Caucasian: *ʁ́IʷV(n)da
Meaning: fence
Abkhaz: ā́nda
Ubykh: wǝdʷá
Comments: Abkh. ā́nda goes back to PAT *ʕanǝda < *ʁ́Ianǝda with delabialisation; Ub. wǝdʷá presupposes PWC *ʁ́Iʷǝ(n)dʷa. We should probably reconstruct a compromising *ʁ́IʷV(n)da with labialising/delabialising assimilations in Ub. and Abkh.
