Editing Cushitic languages (section)

==Hypothesized Cushitic substrate languages==
Some of the ancient peoples of [[Nubia]] are hypothesized to have spoken languages belonging to the Cushitic group, especially the people of the [[C-Group culture]]. It has been speculated that these people left a substratum of Cushitic words in the modern Nubian languages. Given the scarcity of data (all omomastic or [[toponym]]ic), however, it remains unclear if the C-Group culture in fact spoke a Cushitic language.{{sfnp|Rilly|2019|pp=134–137}}

[[Christopher Ehret]] (1998) proposed on the basis of loanwords that South Cushitic languages (called "Tale" and "Bisha" by Ehret) were spoken in an area closer to Lake Victoria than are found today.<ref name="Mous">{{cite book |last1=Kießling |first1=Roland |first2=Maarten |last2=Mous |first3=Derek |last3=Nurse |year=2007 |chapter=The Tanzanian Rift Valley area |title=A Linguistic Geography of Africa |editor=Bernd Heine |editor2=Derek Nurse |chapter-url=https://www.academia.edu/825370 |publisher=Cambridge University Press |access-date=22 March 2020}}</ref><ref>{{Cite journal|jstor = 183030|title = We Are What We Eat: Ancient Agriculture between the Great Lakes|last1 = Schoenbrun|first1 = David L.|journal = The Journal of African History|year = 1993|volume = 34|issue = 1|pages = 1–31|doi = 10.1017/S0021853700032989|s2cid = 162660041}}</ref>

Also, historically, the [[Southern Nilotic languages]] have undergone extensive contact with a "missing" branch of [[East Cushitic languages|East Cushitic]] that Heine (1979) refers to as ''Baz''.{{sfnp|Güldemann|2018}}<ref>Heine, Bernd, Franz Rottland & Rainer Voßen. 1979.
