The following is information I have gleaned from many sources over the last twenty six years. "Parent" languages are to the left; "descendant" languages are indented to the right under the appropriate "parent" language. Other names for the languages will be noted parenthetically.Please be aware that some of the oldest language names denote the geographic region where that language was spoken rather that what the speakers of the language called their language.
This is a simplified diagram of the relationship of various obsolete asiatic languages showing their development throughout history, where possible, from various older languages, all now extinct. It is mostly just a list of unrelated Asiatic languages whose relationships and origins are unknown. This does not include languages in the families known as Finno-Ugric, Indo-European, Afro-Asiatic, African, Ural-Altaic (Asiatic), American Indiginous, Andamanese, Caucasian, or Oceanic. (As I add pages for those language families I will place links to them above.)
I hope this has been useful, enjoyable, or interesting to you. Thanks for taking your time to read this page! If you entered into my site via this page, you may find more useful language study links on my home page.
