''Cambridge Handbook of African Linguistics'', p.326-381.</ref> suggests the following subclassification of Nilo-Saharan:

{{clade
|label1=Nilo-Saharan
|1={{clade
|label1=Northeastern
|1={{clade
|1=[[Maban languages|Maban]]
|2={{clade
|1=[[Kunama languages|Kunama]]
|2=[[Fur languages|Fur]]
}}
|3={{clade
|1=[[Saharan languages|Saharan]]
|2=[[Eastern Sudanic languages|Eastern Sudanic]] (including [[Berta languages|Berta]])
}}
|4=[[Kuliak languages|Kuliak]]
}}
|2=[[Central Sudanic languages|Central Sudanic]]
}}
}}

Dimmendaal et al. consider the evidence for the inclusion of [[Kadu languages|Kadu]] and [[Songhay languages|Songhay]] too weak to draw any conclusions at present, whereas there is some evidence that [[Koman languages|Koman]] and [[Gumuz languages|Gumuz]] belong together and may be Nilo-Saharan.<ref>{{cite book|first=Gerrit J.|last=Dimmendaal|title=Historical Linguistics and the Comparative Study of African Languages|year=2011|publisher=John Benjamins|isbn=978-90-272-8722-9|page=313}}</ref>

The large Northeastern division is based on several typological markers:
* tolerance of complex [[syllable structure]]
* higher amount of both inflectional and derivational morphology, including the presence of [[case (linguistics)|cases]]
* verb-final (SOV or OSV) word order
* [[coverb]] + [[light verb]] constructions
* [[converb]]s
