Persian, Dari, Tajik: Language Evolution and Varieties The transition from the Sasanian Empire to the Islamic period marked a crucial shift in the Persian language. Following the Arab-Islamic conquest (632-651 CE), Persian evolved into Early New Persian (ENP), spanning from the 8th to the 12th centuries. This period, characterized by gradual linguistic transformation rather than abrupt change, saw Persian shift from Middle Persian (MP) to a form written in Arabic script. Despite these changes, the linguistic differences between 7th-century MP and 10th-century ENP were less pronounced compared to those between ENP and modern Persian. ENP is notable for its regional and religious varieties. Key types include Standard ENP, used by Muslim Iranians and written in Arabic script; Early Judaeo-Persian (EJP), written in Hebrew script by Persian-speaking Jews; Manichean NP, from northeastern Iran; Christian NP, mainly in Central Asia; and Zoroastrian NP, with texts in Middle Persian and Avestan scripts. Manuscripts from these periods vary in preservation and authenticity, with EJP texts providing particularly valuable insights. The Islamic conquest integrated Iran into the Umayyad and Abbasid caliphates, yet Persian retained its cultural significance. The Samanid Dynasty (819-1005) and later dynasties like the Ghaznavids and Saljuqs played a key role in establishing Persian as a prominent literary and administrative language. By the late 11th century, Persian had become a major language of literature and scholarship, extending its influence across Central Asia and North India. In Afghanistan, Persian (Dari) and Pashto are the primary languages, with Dari serving as the most widely spoken language and Pashto holding official status. Afghanistan’s linguistic landscape reflects its diverse history and geography, with various languages being promoted and preserved. Tajik Persian, or Tojik, is a variant of New Persian used in Central Asia, particularly in Tajikistan and parts of Uzbekistan. It features significant Russian and Uzbek influences and retains some archaic elements of Persian.
