Original: Khowar ( ) , also known as Chitrali , is a Dardic language spoken by 400,000 people in Chitral in Khyber-Pakhtunkhwa , in the Ghizer district of Gilgit-Baltistan ( including the Yasin Valley , Phandar Ishkoman and Gupis ) , and in parts of Upper Swat .
Simplified: Colonel Biddulph ( Tribes of the Hindoo Koosh ) was amongst the first westerners to study Khowar and claimed that further research would prove Khowar to be equally derived from Zend ( Avestan , Old Persian ) and Sanskrit .
