We have Dari translators and interpreters. Dari (Dari: دری‎, [dæˈɾiː]) or Dari Persian (فارسی دری, Fārsī-ye Darī, [fɒːɾsije dæˈɾiː]) or synonymously Farsi (فارسی, Fārsī, [fɒːɾsiː]) is a variety of the Persian language spoken in Afghanistan. Dari is the term officially recognized and promoted since 1964 by the Afghan government for the Persian language, hence, it is also known as Afghan Persian in many Western sources. This has resulted in a naming dispute. Many Persian speakers in Afghanistan prefer and use the name "Farsi" and say the term Dari has been forced on them by the dominant Pashtun ethnic group as an attempt to distance Afghans from their cultural, linguistic and historical ties to the Persian-speaking nations, which includes Iran and Tajikistan.

As defined in the Constitution of Afghanistan, it is one of the two official languages of Afghanistan; the other is Pashto. Dari is the most widely spoken language in Afghanistan and the native language of approximately 25–50% of the population. The Iranian Persian and Dari Persian are mutually intelligible, with differences found primarily in the vocabulary and phonology. By way of Early New Persian, Dari Persian, like Iranian Persian and Tajik, is a continuation of Middle Persian, the official religious and literary language of the Sassanian Empire (224–651 CE), itself a continuation of Old Persian, the language of the Achaemenids (550–330 BC). In historical usage, Dari refers to the Middle Persian court language of the Sassanids.
