They fall into two clusters, East and West, with a limited degree of mutual intelligibility between members of each cluster. The Ogoni think of the cluster members as separate languages, however.
The classification of the Ogoni languages is as follows:
- East: Khana and Tẹẹ, with around 500,000 speakers between them, and Gokana, with about 130,000.
- West: Eleme, with about 70,000 speakers, and Baan, with around 17,500.
