The Dardic languages or Dardu are a sub-group of the Indo-Aryan languages natively spoken in northern Pakistan’s Gilgit Baltistan and Khyber Pakhtunkhwa, northern India’s Jammu and Kashmir, and eastern Afghanistan.
Kashmiri is the most prominent Dardic language, with an established literary tradition and official recognition as one of the national languages of India.
The languages are spoken by tribal peoples in an extremely isolated mountainous region of the Hindukush, one that has never been subject to any real central authority in modern times.
This area is located along the northeastern border of Afghanistan and adjacent portions of the northwest of present-day Pakistan.
These include Kalasha-mondr, Palula, Dameli, Gawar-Bati, Nuristani, Yidgha, Burushaski, Gojri, Wakhi, Kyrgyz, Persian and Pashto.
