I have read that if you know Korean, learning Japanese and Turkish is easy. I have heard Japanese before, sometimes it sounds different from Korean. I know they are related to each other. I have read that Korean could be related to Dravidian languages because of structure and grammar. Sometimes when I hear Indian talk, sometimes I think I am hearing Korean. In fact that was the first thing people thought in the 19th century. I even heard of a link between Korean and Sumerian. Some people think Dravidian could be a branch of Altai-Ural. Dravidians today are often the "Untouchables" in India, they are short and have dark skin.
Sa'ami has apparantly absorbed numerous Uralic-Altaic words from the Finno-Ughric subset of that language group. On the other hand the Sa'ami languages have the same linguistic peculiarities that differentate the Dravidian languages from others with similar word-building techniques.
Turns out a fellow at Indiana University takes credit for having demonstrated that Sa'ami, Sumerian and an Indian language in California are "cognates".
Think of it this way ~ the Dravidian language group is very old. It is located primarily in Southern India. During the Ice Age some people speaking a Dravidian language migrated to the NW, along the coast, to the land of Dilmon. From that point they moved inland along the Euphrates upstream to Assyria, and from there through Ukraine and Russia to the Baltic area. (There is a water route all the way from the Black Sea to the Baltic used by the Greeks, and later by the Vikings.)
When Sumerian was first discovered and was being translated, a bunch of crackpots lept to the conclusion that since the Sumerians discussed glaciers that they must have originated in Scandinavia!
They appear to have had the right idea, but got it backwards!
The old theory was that the Aryans rode in, took over, and there they be. Turns out the Aryans rode in, lost their horses to the natives, but passed along their languages.
