Dari, also known as Afghan Persian, is a member of the Indo-European language family and is one of the two official languages of Afghanistan, along with Pashto. It's the most widely spoken of the two and is used as the lingua franca between ethnic communities. Dari is the language spoken in Afghan schools, and it's used in official capacities in administrative and government settings, for example, and in radio, print media, and television.
What are the differences between Dari vs. Farsi.
The two languages called Dari (spoken in Afghanistan) and Farsi (spoken in Iran) belong to the same linguistic family and are so similar that they're mutually intelligible. Speakers of Farsi and Dari can understand each other as, for example, speakers of different varieties of English can. However, there are important differences between Dari and Farsi. For example, in Farsi, the words for "milk" and "lion" are both pronounced as shir in Farsi, but in Dari they're pronounced differently, as shir and sher, respectively.
Dari and its literary history.
Dari is a language of great literary tradition, with roots that date back to Old Persian. Dari uses the Perso-Arabic script, so words and phrases are written from right to left and many vowel sounds are not represented in writing. The Masnavi, the influential thirteenth-century poem by Rumi, is one of the best-known works of Persian literature.
