Proto-West-Caucasian: *č̣́ač̣́a
Meaning: kidney
Abkhaz: a-č̣́áč̣́a
Abaza: č̣́ač̣́a
Adyghe: źaźǝj
Kabardian: źaźaj
Ubykh: č̣́ā́č̣́a
Comments: PAT *č̣́ač̣́a (cf. also Abkh. Bzyb. a-č̣́áč̣́); PAK *źaźǝ́jǝ. The Abkh. and Ub. form correspond very well to each other and can only go back to PWC *č̣́ač̣́a (note that Ub. also has źaźǝ́ja 'kidney', borrowed from Ad.). However, the phonetic explanation of the PAK form is more difficult (we should also expect *č̣́ač̣́a). Shagirov (1977, 200) divides the AK form into the root *źa- and a diminutive suffix *-źǝjǝ; but we should rather think of a contraction and assimilation *č̣́ač̣́a-źǝjǝ > *č̣́a-źǝjǝ > *źaźǝjǝ. In any case, it is impossible to separate the PAK form from other WC forms.
