Languages
The people of Afghanistan form a complex mosaic of ethnic and linguistic groups. Pashto and Persian (Dari), both Indo-European languages, are the official languages of the country. More than two-fifths of the population speak Pashto, the language of the Pashtuns, while about half speak some dialect of Persian. While the Afghan dialect of Persian is generally termed “Dari,” a number of dialects are spoken among the Tajik, Ḥazāra, Chahar Aimak, and Kizilbash peoples, including dialects that are more closely akin to the Persian spoken in Iran (Farsi) or the Persian spoken in Tajikistan (Tajik). The Dari and Tajik dialects contain a number of Turkish and Mongolian words, and the transition from one dialect into another across the country is often imperceptible. Bilingualism is fairly common, and the correlation of language to ethnic group is not always exact. Some non-Pashtuns, for instance, speak Pashto, while a larger number of Pashtuns, particularly in urban areas, have adopted the use of one of the dialects of Persian.
Other Indo-European languages, spoken by smaller groups, include Western Dardic (Nuristani or Kafiri), Balochi, and a number of Indic and Pamiri languages spoken principally in isolated valleys in the northeast. Turkic languages, a subfamily of the Altaic languages, are spoken by the Uzbek and Turkmen peoples, the most recent settlers, who are related to peoples from the steppes of Central Asia. The Turkic languages are closely related; within Afghanistan they include Uzbek, Turkmen, and Kyrgyz, the last spoken by a small group in the extreme northeast. Afghanistan has very small ethnic groups of Dravidian speakers. Dravidian languages are spoken by the Brahuis, residing in the extreme south.
The present population of Afghanistan contains a number of elements, which, in the course of history and as a result of large-scale migration and conquests, have been superimposed on one another. Dravidians, Indo-Aryans, Greeks, Scythians, Arabs, Turks, and Mongols have at different times inhabited the country and influenced its culture and ethnography. Intermixture of the two principal linguistic groups is evident in such peoples as the Ḥazāra and Chahar Aimak, who speak Indo-European languages but have physical and cultural traits usually associated with the Turkic and Mongol peoples of Central Asia.
