Sumerian language. Sumerian language, language isolate and the oldest written language in existence. First attested about 3100 bc in southern Mesopotamia, it flourished during the 3rd millennium bc. About 2000 bc, Sumerian was replaced as a spoken language by Semitic Akkadian (Assyro-Babylonian) but continued in written usage almost to the end of the life of the Akkadian language, around the beginning of the Christian era.
Although the first known text by native speakers dates to 1885, the first record of the language is a list of words recorded in 1793 by Alexander MacKenzie.ecause of the way languages change gradually, it is usually impossible to pinpoint when a given language began to be spoken. In many cases, some form of the language had already been spoken (and even written) considerably earlier than the dates of the earliest extant samples provided here.
