Reflexes of the *<i>VgV</i> and *<i>VxV</i> groups in the Mongol dialect of the glossary "Dada yu / Beilu yiyu" (late 16th - early 17th century)
The paper deals with the reflexes of Proto-Mongolic *VgV and *VxV groups as occurred in the Dada yu / Beilu yiyu, a little known Sino-Mongol glossary dated between 1567 and 1603. The results obtained from a detailed examination of the glossary’s language material in a historical comparative perspective allow us to draw some nontrivial conclusions about the origin and development of these groups in the Mongolic languages. A combination of archaic and innovative features in the Mongol idiom reflected in the glossary leads us to the conclusion that it may be identified as belonging to a transitional stage between Middle Mongol and Modern Mongolian, with a statistically significant predominance of linguistic features characteristic of the latter. The cases of irregular and unpredictable fluctuation between intervocalic *g, *k, *x in the Mongolic languages are discussed as well. A new scheme of the development of Proto-Mongolic intervocalic velars from a common source is proposed by the author, which may refine and elaborate the existing Proto-Mongolic reconstructions.
