Some language families that originated in the Caucasus region include Northwest Caucasian, Northeast Caucasian, and Kartvelian. In the Ural region, languages from the Uralic language family, such as Finnish, Hungarian, and Estonian, originated.

I don't believe Caucasians speak any other language but english or any european language. A caucasian can be a mix between a European ethnicity and "Indo-European". You can tell a little bit if a person is Caucasian by their curly or wavy hair and light or slightly tan skin. But its respectful to ask first. :)

Georgian belongs to the Caucasian family of languages.

Guatemala is just northwest of El Salvador and has 23 officially recognized indigenous languages
