NARROWING OF DIPHTHONGS ИЕ, ИĒ, УО, УŌ IN FORMATION OF TIME FORMS IN CHECHEN AND INGUSHIAN LANGUAGES

Abstract

The paper examines a problem associated with the peculiarities of the process of narrowing the primary diphthongs ue, uē of the first row of the middle rise and diphthongs yo, yō of the back row of the middle rise in the structure of the verbs of the studied languages with the involvement of facts from the dialects of the Chechen language, which in some cases retained the most archaic forms. If one compares the named type of assimilation with other Nakh languages, then it is represented in the Chechen literary language more extensively. A comparative analysis of the process of narrowing the diphthongs ie, iē, yo, yō in the verb stems shows that there are significant features between the Nakh (Chechen, Ingush, Batsbi) languages and dialects of the Chechen language. The authors conclude that one of the most important processes in the study of the Nakh languages is the regressive-remote assimilation of vowel phonemes.
