Proto-Turkic languageとは 意味・読み方・使い方

The Proto-Turkic language is the proto-language of the family of Turkic languages that predates the separation of the Turkic peoples and separation into Oguz and Ogur branches. The Ogur languages are characterized by sound correspondences such as Oguric r versus Common Turkic z (Proto-Turkic *ŕ) and Oguric l versus Common Turkic š (Proto-Turkic *ĺ). Oguric is sometimes referred to as Lir-Turkic and Common Turkic as Shaz-Turkic. The glottochronological reconstruction based on analysis of isoglosses and Sinicisms points to the timing of the r/š split at around 56 BCE-48 CE, associated with "the historical situation that can be seen in the history of the Huns' division onto the Northern and Southern: the first separation and withdrawal of the Northern Huns to the west has occurred, as was stated above, in 56 BC,...the second split of the (Eastern) Huns into the northern and southern groups happened in 48 AD, from that time the Northern Huns gradually shifted to the Western Mongolia and later to the East Turkestan, to Dzungaria, and in 155 AD they migrated to the East Kazakhstan and Jeti-su, where they lived till the 5th c.
