[1] The about 22 (SIL estimate) Western Nilotic languages are spoken in an area ranging from southwestern Ethiopia and South Sudan via northeastern Democratic Republic of the Congo and northern Uganda to southwestern Kenya (with one of the Luo languages extending into northern Tanzania).
Western Nilotic is divided into two main clusters: Dinka–Nuer and Luo.
They include but are not fully limited to, Shilluk, Luwo, Thuri, Belanda Bor, Burun, Päri, Anuak, and Southern Luo.
[3] The Dinka-Nuer Languages are the larger of the two subgroups and are spoken primarily in South Sudan.
It is also popular belief of linguists that Burun is a third subgroup of Western Nilotic.
