Elamite language
The Elamite language (c. 3000 BCE to 400 BCE) is the now-extinct language spoken by Elamites, who inhabited the regions of Khūzistān and Fārs in Southern Iran. It has long been an enigma for scholars due to the scarcity of resources for its research and the irregularities found in the language. It seems to have no relation to its neighboring Semitic and Indo-European languages. Scholars fiercely argue over several hypotheses about its origin, but have no definite theory.
