Tasawaq language  Tasawaq (Tuareg name: "Tesăwăq"), 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.
