The Nilotic languages are a group of Eastern Sudanic languages spoken across a wide area between South Sudan and Tanzania by the Nilotic peoples , who traditionally practice cattle-herding.
Among these are the Luo , Sara , Maasai , Kalenjin , Dinka , Nuer , Shilluk , Ateker , and the Maa-speaking peoples , each of which is a cluster of several ethnic groups.
Nilotic peoples are peoples indigenous to the Nile Valley who speak Nilotic languages ; this is a large sub-group of the Nilo-Saharan languages spoken in South Sudan , Uganda , Kenya , and northern Tanzania.
In a more general sense , the Nilotic peoples include all descendants of the original Nilo-Saharan speakers.
However , the largest branch by far is Nilotic , spread by extensive and comparatively recent conquests throughout East Africa.
In most classifications , the Eastern Sudanic languages are a group of nine families of languages that may constitute a branch of the Nilo-Saharan language family.
Eastern Sudanic languages are spoken from southern Egypt to northern Tanzania.
