Elamite is an extinct language spoken by the ancient Elamites. Elamite was the primary language in present-day Iran from 2800–550 BC. The last written records in Elamite appear about the time of the conquest of the Persian Empire by Alexander the Great. Elamite has no demonstrable relatives, and is usually considered a language isolate. Partly due to the lack of established relatives, interpretation of the language is difficult.
