Chari-Nile is a proposed language family within the larger Nilo-Saharan macro-family. It includes several language groups spoken primarily in Chad, Sudan, and neighboring countries. These languages are thought to share common ancestry. The exact composition of Chari-Nile and its relationship to other Nilo-Saharan languages is debated. Think of it as a branch on a family tree, still under investigation. It is like a sub-genre of music within a larger genre.
