The twenty Central Plateau languages are a residual branch of the Plateau family spoken in central Nigeria. Tyap (or Katab) has 130,000 speakers, and the closely related Jju (or Kaje) has well over 300,000. Hyam (or Jabba) has another 100,000. Cori is famous for being one of very few languages with six tone levels, though only three are needed for writing.
The Central Plateau languages are a close geographical group with numerous connections; however, they are to some extent a residual group and may be a sprachbund. The following classification is taken from Blench (2008). A distinction between North Plateau and the rest of Central Plateau is possible but appears to be geographic; Gerhardt (1994) argues they belong together.
Each of the second-level bullets is a single language or dialect cluster and is obviously valid. However, most of the first-level groups (Hyamic, North Plateau, Gyongic, Koro) are not self-evident and may continue to be revised.
