Proto-West-Caucasian: *x́ǝ
Meaning: 1 cold 2 to get cold, freeze
Abkhaz: á-χ́-š̌aš̌a 1
Abaza: χ́-šʷašʷa 1
Adyghe: š́-tǝ- 2
Kabardian: ś-tǝ- 2
Comments: PAT *x́ǝ is attested both separately (Abaz. χ́-ra 'get cold, cool down') and within compounds (PAT *χ́ǝ-ta 'cold (n.)' > Abkh. á-χ́ta, Abaz. χ́ta, *χ́ǝ-sʷasʷa 'cold (adj.)' (with an unclear second component), *ʒǝ-χ́ǝ 'cold water, spring' (Abkh. a-ʒǝ́χ́, Abaz. ʒǝχ́).
PAK *š́ǝtǝ- = PAT *x́ǝ-ta. Abdokov (1983, 104) attempts to relate the PAT root (separated from PAK) to Arch. χIe- 'cold'; this is obviously impossible (the Archi form, along with a number of other EC reflexes, goes back to PEC and PNC *=HĭGĀ q.v.).
