Teda language
The Teda language, also known as Tedaga, Todaga, Todga, or Tudaga is a Nilo-Saharan language spoken by the Teda, a northern subgroup of the Toubou people who inhabit southern Libya, northern Chad and eastern Niger. A small number also inhabit northeastern Nigeria.
Along with the more populous southern dialect of Daza, the northern Teda dialect constitutes one of the two varieties of Tebu. However, Teda is also sometimes used for Tebu in general.
