There are five Edo languaees called Southwestern Edo. They are Eruwa, Isoko, Okp~. Urhobo; and Uvbi~.l The ~do languages a~e mostly spoken in Bendel State, though there are some spoken in the Rivers and Ondo States. Greenberg [1966:9] classifies Edo as a Kwa subgroup: e; Elugbe [1973] classifies Southwestern Edo with Delta Edo (the Edo languages of the Rivers State) as co-ordi~ate branches of a South'~do branch of ~do. Isoko and Urhobo are the best known of the Southwestern ~do languages, while the other three are often spoken of as dialects of these two: Eruwa, as a dialect of Isoko (a fact strengthened by the political and economic dominance of Isoko); Okp~ and Uvbi~ (also called Evhron in the literature) as dialects of Urhobo. As a matter of fact, these people refer to themselves as Urhobo and invariably also speak Urhobo, which is taught in the schools and used as a lingua franca in the Urhobo Divisions. The following discussion will be based on the Uzere dialect of Isoko and the Agbarho dialect of Urhobo. All these languages, none of which has extensive literature and little or none on tone, exhibit (with the exception of Eruwa, to judge by Odumosu [1973]) a phenomenon of final low tone raising.
