Omo–Tana languages

The Omo–Tana languages are a disputed branch of the Cushitic family and are spoken in Ethiopia, Djibouti, Somalia, and Kenya. The largest member is Somali. There is some debate as to whether the Omo–Tana languages form a single group, or whether they are individual branches of Lowland East Cushitic. Blench (2006) restricts the name to the Western Omo–Tana languages, and calls the others Macro-Somali.

Internal classification
Mauro Tosco (2012) proposes the following internal classification of the Omo-Tana languages. Tosco considers Omo-Tama to consist of a Western branch and an Eastern ("Somaloid") branch, which is a dialect chain of various Somali languages and the Rendille–Boni languages (see also Macro-Somali languages).
