Протонахский: *cħa
Значение: one
Чеченский: cħaʔ
Ингушский: caʕ
Бацбийский: cħa
Комментарии: The final glottal stop is probably secondary (like in other numerals), but it led to an assimilatory development *cħaʔ > caʕ in Ing. (cf. without it forms like cħä "single", cħa-nne /obl. base of caʕ/ etc.).
