Sumerian was an ancient language used in Southern Mesopotamia. The language had been long forgotten and researchers rediscovered inscriptions during the 19th century. The Sumerian language is unlike any other language in the world.
Two varieties (dialects or sociolects) of Sumerian are recorded. The standard variety is called eme-ĝir (ĝ pronounced [ŋ]). The other recorded variety is called eme-sal (EME.SAL "fine tongue") . The name is usually translated as "women's
language". Eme-sal is used exclusively by female characters in some
literary texts (this may be compared to the female languages or
language varieties that exist or have existed in some cultures, e.g.
among the Chukchis and the Caribs, and to women's use of Prakrit as opposed to men's use of Sanskrit
in some of the Indian classics); in addition, it is dominant in certain
genres of cult songs etc.. The special features of eme-sal are mostly
phonological (e.g. m is often used instead of ĝ as in me vs standard ĝe26, "I"), but words different from the standard language are also used (e.g. ga-ša-an vs standard nin,
"lady"). Sumerian words adapted into Akkadian were sometimes of the
eme-sal variety, so that it may have been the more colloquial variety. (Wiki)
