Sumerian language

Sumerian ( "native tongue") was the language of ancient Sumer, spoken in Southern Mesopotamia since at least the 4th millennium BC. It was gradually replaced by Akkadian as a spoken language in the beginning of the 2nd millenium BC, but continued to be used as a sacred, ceremonial, literary and scientific language in Mesopotamia until the first century AD. Then, it was forgotten until the 19th century. Sumerian is a language isolate.
