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.

It shares some similarities with Berber languages, e.g. Tamasheq. For example in both languages, the grammatical gender of a noun is female if it begins and ends with the letter t.
