エラム語
The use of the Elamite language as an administrative language was first attested in texts of ancient Ansan, Tall-e Mal-yan, dated 1000 BCE. Previous to the era of Elamites, the Akkadian language was responsible for most or all of the text used in ancient documents. Susiana was incorporated by Sargon the Great into his Akkadian Empire in approximately 2330 BCE.
