The Dinka Lanaguage
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, Twic/Tuic East, and Bor, which are distinct enough to require separate literary standards and thus to be considered separate languages. Jaang or Jieng is used as a general term to cover all Dinka languages. The Rek Dialect is said to be the standard and prestige dialect. The closest non-Dinka language is Nuer, the language of the Dinka’s traditional rivals. The Luo languages are also closely related.
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.
