A long vowel sound [a] in nominal word forms of the Toles subdialect in the Ulagan dialect of the Telengit language (a comparative aspect)

This article considered the nominal word forms with a long vowel [a] in the Toles (cholushman) dialect of the Ulagan dialect in the Telengit language. The speakers of this dialect live compactly in the settlements of Balykcha, Koo of the Cholushman Valley, located on the southern coasts of the Teletskoye Lake. The novelty of the study is that for the first time the Telengits language is divided into the Ulagan dialect and the Chuya dialect. The Ulagan dialect is the language of Telengits, who live compactly on the territory of the Ulagan district, the Chuy dialect is the Telengits language spoken on the territory of the Kosh-Agachsky District of the Altai Republic. In turn, each dialect is divided into several subdialects. The Ulagan dialect is divided into six subdialects on the basis of geographical position and specific linguistic traits, among which is the Toles (Cholusman) subdialect. The long vowel phonemes of the Ulagan dialect in general and the Toles (cholushman) subdialect in particular had not been researched in detail before. The development of the topic is important and highly promising from a purely scientific point of view since it introduces new research material, reveals the phonetic features of the hitherto unknown language. A long vowel [a] in the Toles (Cholushman) subdialect is used in anlaut, inlaut, and auslaut of nominal word forms. A long vowel sound [a] in the Toles (Cholushman) subdialect is found in root and non-root nominal word forms; it is used in word-forms-monosyllabs and word forms-bisillabs of different syllabic structure. Comparative analysis made it possible to conclude that the long vowel [a] was formed in the Toles native root word-forms-monosyllabs mainly as a result of the dropping of the in-lute consonant; in the root word forms-bisillabs, a long vowel [a] was formed in the position in front of the narrow vowel of the second syllable; in non-root nominal-word forms of bisillabs, a long vowel [a] was formed when the affixes with a narrow vowel morphologically increased, as well as due to the loss of the intervocal consonant. The Toles (Cholushman) word forms with long vowels [a] find common features with the majority of dialects of the Ulagan dialect, with the exception of the Chibits dialect, which in its phonetic characteristics is close to the Chuya dialect. The Toles (Cholushman) and generally Ulagan word forms with a long vowel [a] reveal both general phonetic features and differences with the Altai-kizhi dialect, but the Ulagan dialect differs significantly from the Altai literary language. It is established that Altai-kizhi dialect and Altaic literary language are not the same, despite the fact that this dialect is the basis of the literary language.
