Tetserret is a Tuareg dialect similar to northern Berber languages. It is spoken mainly by the Ait-Awari tribe of the Akabinu or Akoubounou commune in Niger. The name, also Shinsert or Tin Sert, means 'the language of Sirte'.
It contains vocabulary similar to different Berber languages in North-Africa, and may link the Tuareg and northern Berber languages. For example, afagan (man) resembles Moroccan Tamazight; aiddid (goatskin container for water) resembles Ghadames; and awdosh (ox) recalls Hassaniya Arabic.
