Waigali is a language spoken by about 10,000 Nuristani people of the Waigal Valley in Afghanistan's Nuristan Province. The native name is Kalaṣa-alâ 'Kalasha-language'. "Waigali" refers to the dialect of the Väy people of the upper part of the Waigal Valley, centered on the town of Waigal, which is distinct from the dialect of the Čima-Nišei people who inhabit the lower valley. The word 'Kalasha' is the native ethnonym for all the speakers of the southern Nuristani languages.
