Proto-West-Caucasian: *tǝχʷǝrǝ
Meaning: foam
Adyghe: tχʷǝrb
Kabardian: tχʷǝrǝmba
Comments: PAK *tχʷǝ́r-ba / *tχʷǝrǝ́-mba. Ad. > Ub. tχʷǝ́rba 'foam' (see Dumézil 1931, 211, Shagirov 2, 78). The element *-(ǝm)-ba in PAK is not quite clear. Despite Dumézil (1932, 107, 108), the AK form can not be related to Ub. šχʷabǝ́ 'foam', since the latter is clearly connected with PAT *sʷaqǝ 'foam' ( < PWC *šʷaq:V q.v.).
