Editing Nilo-Saharan languages (section)

===Bender 1989, 1991===
[[Lionel Bender]] came up with a classification which expanded upon and revised that of Greenberg. He considered Fur and Maban to constitute a [[Fur–Maban languages|Fur–Maban]] branch, added [[Kadu languages|Kadu]] to Nilo-Saharan, removed Kuliak from Eastern Sudanic, removed Gumuz from Koman (but left it as a sister node), and chose to posit [[Kunama languages|Kunama]] as an independent branch of the family. By 1991 he had added more detail to the tree, dividing Chari–Nile into nested clades, including a Core group in which [[Berta languages|Berta]] was considered divergent, and coordinating Fur–Maban as a sister clade to Chari–Nile.<ref>[[Lionel Bender|Bender, M.

Bender revised his model of Nilo-Saharan again in 1996, at which point he split Koman and Gumuz into completely separate branches of Core Nilo-Saharan.<ref name="Bender (1996)">{{cite book |author-link=Lionel Bender (linguist) |first=Lionel |last=Bender |year=1996 |title=The Nilo-Saharan languages: a comparative essay |location=Munich |publisher=Lincom Europa }}</ref>
