However, it is believed that the language of Zemgale still be closer to the Lithuanian language, than to the Curonian and Latvian languages. The explanation for this assumption lies in the membership of both languages to a group of Eastern Baltic languages. Selonsky or seliysky language belongs to the Baltic tribe Celoni or Sellonian. Name of a tribe mentioned in the historical documents of the 13 th century. The word probably comes from the river He sat down in the valley and which housed the tribe. Sela bordered Zemgale, Latgale and Kriviches. Scientists point to the location of the territory Celoni in the north-east of present-day Lithuania. It is assumed that the language of the tribe had disappeared by mid-14 th century: in the northern part of the territory he was replaced by the Latvian language, and in the south – Lithuanian.
Undoubtedly, in the Baltic Sea have taken place other dialects and languages, belonging to the ancient Balts. But their names are today unknown to scientists. So, we should mention several areas in Eastern Europe, where the presence of the Baltic languages is unquestionable. There are two major premises. This is the Dnieper area, which includes the northern part of the Dnieper River Basin (from its origins to the city of Kiev) and the terrain in the basin of the Oka River. Distribution of the Baltic languages in these areas has quite uneven. In the languages of these regions is used quite a lot of the Baltic hydronyms.
More recently, scientists have discovered another area within which applies a huge number of hydronyms Baltic origin. This area is located in the upper reaches of the Don River and bordered it with the area where used Finnish dialects – Volga-Finnish or territory of Mordovia. In recent years, been expanding the use of the Baltic region hydronyms the area between the lake Ilmenna in northern and upper reaches of the river Dvina in the southern part. Most likely, this region is part of the whole the Upper Range Baltic hydronyms. Also, scientists have suggested that the name of the Volga river, too, has the Baltic roots. When closing the final article, you will notice that the list of extinct Baltic languages is quite large, considering those languages that probably existed on the territory of the Baltic Sea in ancient times. Loss known as "dead" languages, has led to what existed in ancient times the territory that was inhabited by baltoyazychnye tribes, was significantly reduced, and the variety of the Baltic languages and dialects that existed in antiquity, was reduced in the long run to just two languages: Lithuanian and Latvian. Nowadays, scientists and linguists have been working towards the revival of extinct languages, or at least some of their parts. In Vilnius State University, even put a stone which testifies to the memory of grateful descendants of their ancestors.
