Proto-West-Caucasian: *rǝɣʷǝ
Meaning: mouse
Ubykh: dǝʁʷǝ́
Comments: The word is isolated in Ub. (for phonetic reasons a comparison with PAK *c:ǝʁʷá 'mouse' and PAT *cǝɣǝ 'marten' is not possible), but has very probable parallels in EC languages. The Ub. form may reflect PWC *d-,*t:- or *r-; *-ʁʷ-,*-Gʷ- or *-ɣʷ-; the form *rǝɣʷǝ is thus only one of the possible variants of the PWC reconstruction, fitting best for the EC data.
