The Norwegian linguist Georg Morgenstierne wrote that Chitral is the area of the greatest linguistic diversity in the world. Although Khowar is the predominant language of Chitral, more than ten other languages are spoken here. These include Kalasha-mun, Erina, Savi Palula, Dameli, Gawar-Bati, Nuristani, Yidgha, Burushaski, Wakhi, Kyrgyz, Persian and Pashto. Since many of these languages have no written form, letters are usually written in Urdu or Persian
