Middle Persian

Southwestern Iranian language

Middle Persian, also known by its endonym Pārsīk or Pārsīg in its later form, is a Western Middle Iranian language which became the literary language of the Sasanian Empire. For some time after the Sasanian collapse, Middle Persian continued to function as a prestige language. It descended from Old Persian, the language of the Achaemenid Empire and is the linguistic ancestor of Modern Persian, the official language of Iran, Afghanistan (Dari) and Tajikistan (Tajik).
