立陶宛人从遥远的荒古时代起就一直居住在波罗的海沿岸。语言学方面的资料对此提供了很好的证明。此外,地形学方面的一些名称和大量的其他历史资料也能充分地说明这一点。立陶宛人与斯拉夫人的关系、长期以来十分紧密。就是在印欧语系各族人已经分化而各自独立的时候,立陶宛和斯拉夫人之间仍保持着一个统一的“波罗的-斯拉夫”共同体。退一步讲,即使这种共同体算不上十分完备,其间关系之密切也足以概见。双方虽存在着方言的差别,但可构成一个统一的波罗的-斯拉夫语族,彼 Lithuanians have lived on the Baltic coast since the distant days of aridity. Linguistic information provides a good proof of this. In addition, some of the topographic names and a large number of other historical sources can fully illustrate this point. The relationship between Lithuanians and the Slavs has long been very close. It is at a time when the peoples of Indo-European languages ​​have been separated and independent, Lithuania and Slavs still maintain a common “Baltic-Slavic” community. Step back and forth, even if this community is not very complete, the relationship between the close enough to make it clear. Although the two sides differ in dialect, they can form a unified Baltic-Slavic ethnic group.
