Kabardian: xat
Ubykh: š́ǝ
Comments: PAK *xá-tǝ. Abdokov (1973, 23, 72) and Shagirov (2, 104) are quite right in comparing this morpheme with Ub. š́ǝ and rejecting Trubetzkoy's (1930, 80) comparison of Ub. š́ǝ with Bzhed., Shaps. śǝ-d 'what'. Semantically and phonetically the comparison š́ǝ = AK *xa- is blameless.
