Wurm and Hattori (1981) considered its three principal dialects, Fasu, Some and Namumi, to be three languages, which they called the West Kutubuan family. However, Glottolog and Usher consider Fasu to be a single language.
Fasu is not particularly close to the two East Kutubuan languages, though Usher reconfirms a connection.
Although Fasu has proto-TNG vocabulary, Malcolm Ross considers its traditional inclusion in TNG to be somewhat questionable. Other researchers agree.
