Excerpt from change request document:
Seven years ago, Dawro was already considered to be separate from Gamo and Gofa. At that time, plans were made to begin a language development project in the Dawro language. In 2001, according to the Education Bureau of the Southern Nations, Nationalities and Peoples Regional State (SNNPR), both the Gamo-Gofa Zone and the Dawro Zone were developing their own education materials. Currently, Gamo and Gofa are also considered to be linguistically separate, each having their own language development project as of 2004.
All of the Central Ometo speech varieties are quite similar, but there are some definite divisions along ethnic lines. For example, Wolaytta is a Central Ometo speech variety closely related to Gamo, Gofa and Dawro. However, these three have such a strong separate identity that they are not able to have a common body of literature with Wolaytta (this was established even before Dawro was split from the other two). The grouping of Gamo, Gofa and Dawro is now no longer possible due to political and identity reasons, and at least according to lexicostatistics there is no more cause for them to be grouped with each other than there is for them to be grouped with Wolaytta. In one study, the lexical similarity between these three was less than or equal to their similarity with Wolaytta (Girard 2002). See also the lexicostatistical data quoted in the Ethnologue (Gordon 2005).
