Old Persian is one of two directly attested Old Iranian languages and is the ancestor of Middle Persian. Like other Old Iranian languages, it was known to its native speakers as ariya (Iranian). Old Persian is close to both Avestan and the language of the Rig Veda, the oldest form of the Sanskrit language. All three languages are highly inflected.
