Neither are the languages spoken by the Finns,the Hungarians,and the Mari. They are related to each other,but are also not related to the Basque language.
BTW,the Mari are the native people of a section of modern day Russia called the "Mari Republic". For lack of a better description,they are a tribe of "Russia's Indians."It's about 600 KM's from Moscow,and "Yoshkar-Ola" is the capital town. I've been there and visited the Mari National Museum,and it is a fascinating place. You would swear you are looking at Cherokee artifacts. The Mari even looked like Cherokees.
I think it is really fascinating that three seperate cultures that far apart could share a language base that is in no way related to any of the languages that surround them.
We had 28 Japanese engineers (they brought their families) visit our factory for about a year. We had a 'family day picnic' and everyone brought their kids. A mfg mgr friend of mine was an American Indian (don't know what tribe) and at the picnic he asked me if I could pick out his kids who were playing in a group of Japanese kids. I could not. He (as well as myself) was amazed at how closely they resembled each other.
Maybe this is why: The Zuni Enigma A good book, she makes a convincing case.
If you're into this stuff, read The Tarim Mummies by Mallory & Mair. It's about the Caucasian mummies found in the desert in east central China. (Powerful)
Also Estonian. Estonian language is almost the same as that of the Finnish.
The closest language to Finnish is Estonian. All these languages are Altaic, and related to many languages of northern Russia. Also to Japanese and Korean.
Basque is the big mystery. .. along with some Amerindian languages (Zuni and Navajo, I think).
