Eastern Sudanic languages in the context of "Central Sudanic languages"

The Northern Eastern Sudanic, Eastern k Sudanic, Ek Sudanic, NNT or Astaboran languages may form a primary division of the proposed Eastern Sudanic family. They are characterised by having a /k/ in the first person singular pronoun "I/me", as opposed to the Southern Eastern Sudanic languages, which have an /n/. Nyima has yet to be conclusively linked to the other languages, and would appear to be the closest relative of Ek Sudanic rather than Ek Sudanic proper.

The most well-known language of this group is Nubian. According to Claude Rilly, the ancient Meroitic language appears on limited evidence to be closely related to the languages of this group.

The Western Nilotic languages are one of the three primary branches of the Nilotic languages, along with the Eastern Nilotic languages and Southern Nilotic languages, themselves belonging to the Eastern Sudanic subfamily of Nilo-Saharan. 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).

The Surmic languages are a branch of the Eastern Sudanic language family.

Today, the various peoples who speak Surmic languages make their living in a variety of ways, including nomadic herders, settled farmers, and slash and burn farmers. They live in a variety of terrain, from the lowlands of South Sudan and the banks of the Omo River to mountains over 2,300 meters.

The Eastern Nilotic languages are one of the three primary branches of the Nilotic languages, themselves belonging to the Eastern Sudanic subfamily of Nilo-Saharan; they are believed to have begun to diverge about 3,000 years ago, and have spread southwards from an original home in Equatoria in South Sudan. They are spoken across a large area in East Africa, ranging from Equatoria to the highlands of Tanzania. Their speakers are mostly cattle herders living in semi-arid or arid plains.

The Southern Eastern Sudanic, Eastern n Sudanic, En Sudanic or Kir-Abbaian languages form one of two primary divisions of the Eastern Sudanic languages in the classification of Bender (2000). It is rejected as an established group in Starostin (2015).

The Southern Eastern Sudanic languages are characterized by having an /n/ in the pronoun "I/me", as opposed to the Northern Eastern Sudanic languages, which have a /k/. The best known Southern Eastern Sudanic language group, as well as the largest, is Nilotic, which includes such languages as Maasai.

The Nyima languages are a pair of languages of Sudan spoken by the Nyimang of the Nuba Mountains. They appear to be most closely related to the Eastern Sudanic languages, especially the northern group of Nubian, Nara and Tama.
