Dinka, or Thuɔŋjäŋ, is a Nilotic dialect cluster spoken by the Dinka people, the major ethnic group of South Sudan. There are five main varieties, Ngok, Rek, Agaar, Dinka Leekrieth and Bor, which are distinct enough to require separate literary standards and thus to be considered separate languages. Jaang, Jieng or Moinyjieng is used as a general term to cover all Dinka languages. Rek is the standard and prestige dialect.
The Dinka are found mainly along the Nile, specifically the west bank of the White Nile, a major tributary flowing north from Uganda, north and south of the Sudd marsh in southwestern and south central Sudan in three provinces: Bahr el Ghazal, Upper Nile, and Southern Kurdufan.
