In the course of its development, Old Persian experienced a fast, thorough a restructuring during the Achaemenid period. This development was so great that it marked the beginning of the Middle era in Western Iranian languages. Similar to some other middle IE languages like English, Western Iranian languages are analytic languages which have lost a great part of their complexity in their transition from the Old type to the Middle one. The present article tries to provide some examples regarding the processes of regularization, loss of redundancy, and growth in transparency, as suggested in sociolinguistic typology (Trudgill 2010). As such, the development of Old Persian into Middle Persian is shown to be parallel to major developments in the ancient Iranian society after the rise of Achaemenids.
