Комментарии: Although in Chech. and Ing. the stem =ēq̇- is both terminative and durative, the Bacbi data show that originally it was only terminative: Bacbi has term. =eq̇- opposed to dur. ʔaq̇- 'to divide' ( < PN *ʔāq̇-). A common Nakh derivate is *d-āq̇a 'part, piece' > Chech. dāq̇a, Ing. daq̇a, Bacb. daq̇ / dāq̇.
