Dari (دری ) or Dari Persian, also known as Eastern Persian, is a historical name for the Persian language and refers to the dialects of the Persian language that are spoken in Afghanistan. Dari is an official language of Afghanistan next to Pashto. Dari is also the administrative language of Afghanistan. In Afghanistan Dari Persian is also simply called Persian. It should not be confused with the Dari language of Iran.
Dari Persian is considered to be a more archaic form of (New) Persian. It is the major language of Afghanistan, one of the two official languages (next to Pashto). In practice though it serves as the de facto lingua franca among the various, different ethno-linguistic groups. Dari Persian dominates in the northern and western parts, and the capital, Kabul, in the east.
Dari Persian has contributed to the majority of Persian borrowings in South Asian languages, such as Hindi-Urdu, Punjabi, Bengali, etc., as it was the administrative and cultural language of the Mughal Empire and was the administrative language in the Indian subcontinent for centuries.
Linguists use the terms Western Persian (Farsi) for the spoken Persian in Tehran, and Eastern Persian (Dari) for the Persian spoken in most of Afghanistan, eastern Iran, and Pakistan. The language name of Afghanistan was officially changed from Farsi to Dari due to political reasons in 1964.
