The Elamite language endonym of Elam as a country appears to have been Haltamti.
Exonyms included the Sumerian names NIM.MAki𒉏𒈠𒆠 and ELAM, the Akkadian Elamû (masculine/neuter) and Elamītu (feminine) meant "resident of Susiana, Elamite".
In prehistory, Elam was centered primarily in modern Khuzestān and Ilam. The name Khuzestān is derived ultimately from the Old Persian Hūjiya (Old Persian: 𐎢𐎺𐎩) meaning Susa/Elam. In Middle Persian this became Huź "Susiana", and in modern Persian Xuz, compounded with the toponymic suffix -stån "place".
