There was no topic for this interesting Indo-Aryan language.
Khowar is spoken natively in the North-West of Pakistan. It has a relatively low number of native speakers (estimatedly less than one million) given the size of the country. According to various internet sources, it is mostly in use in the Khyber Pakhtunkhwa and the Gilgit-Baltistan provinces.
It is classified as a Dardic language, like Pashai and Kashmiri (among others).
Efforts appear to have been made in order to write and standardize the language as there is a daily bilingual Khowar / Urdu newspaper called Chitral Vision. A Khowar Academy was also created more than a decade ago.
Khowar is said to have been heavily influenced by the neighbouring Iranian languages, most notably Dari and Pashto.

The only widely available systematic approach to the grammar and lexicon of the language is in French. It is a great book, but with only 176 pages it can't be considered exhaustive.
