Tasawaq language
Tasawaq, sometimes also called Ingelshi, is a Northern Songhay language spoken by the Issawaghan or Ingalkoyyu, a community surrounding the town of In-Gall in Niger. A closely related variety called Emghedeshie was spoken in Agadez but is now extinct.
Like other Northern Songhay languages, it has been strongly influenced by neighbouring Tuareg languages.
