REFLEXES OF "PRIMARY" VOWEL LENGTH IN TURKIC LANGUAGES
The article shows that almost all groups of Turkic languages somehow retain traces of such opposition. A number of languages developed on the basis of quantitative opposition of other prosodic features, mainly in the phonetic mode. These functions need further research. The study of these processes, partly phonetic, but largely morphological, is absolutely necessary as a condition for the inclusion of the relevant material in the reconstruction. The problem of reconstructing the opposition of vowel length for proto-Turkic. It is shown that almost all groups of Turkic languages somehow retain traces of such opposition. A number of languages developed on the basis of quantitative opposition of other prosodic features, mainly in the phonetic mode; these functions need further research.
