Proto-West-Caucasian: *ƛ̣ʷA
Meaning: earth
Adyghe: č̣ǝ
Kabardian: ṣ́ǝ
Ubykh: jǝ-cʷá
Comments: PAK *č̣ǝ. Its regular Ub. correspondence is present in Ub. jǝ-c̣ʷá- 'on the earth' (preverb); reasons for deglottalisation of -c̣ʷ- in the Ub. noun (which is certainly representing the same root) are not yet clear. This root is to be strictly kept apart from PAK *č̣a 'bottom' which has quite different external parallels.
