The languages of Ethiopia refers to the various spoken forms of communication in Ethiopia. It includes the nation's official languages, as well as its minority and foreign languages.
There are 90 individual languages of Ethiopia according to Ethnologue, with the 1994 Ethiopian census indicating that some 77 tongues were spoken locally. Most of these languages belong to the Afro-Asiatic family (Semitic and Cushitic; Omotic languages are also spoken, though their classification is uncertain). Additionally, Nilo-Saharan languages are spoken by the nation's Nilotic ethnic minorities.
Charles A. Ferguson proposed the Ethiopian Language Area, characterized by shared grammatical and phonological features in 1976. This language area (sprachbund) includes the Afro-Asiatic languages of Ethiopia, not the Nilo-Saharan languages. In 2000, Mauro Tosco questioned the validity of Ferguson's original proposal. There is still no agreement among scholars on this point, but Tosco has at least weakened Ferguson's original claim.
English is the most widely spoken foreign language and is the medium of instruction in secondary schools and universities. Amharic was the language of primary school instruction, but has been replaced in many areas by local languages such as Oromo and Tigrinya.
After the fall of the Derg regime in 1991, the new constitution of the Federal Democratic Republic of Ethiopia granted all ethnic groups the right to develop their languages and to establish mother tongue primary education systems. This is a marked change to the language policies of previous governments in Ethiopia.
In terms of writing systems, Ethiopia's principal orthography is Ge'ez or Ethiopic. Employed as an abugida for several of the country's languages, it first came into usage in the 6th and 5th centuries BC as an abjad to transcribe the Semitic Ge'ez language. Ge'ez now serves as the liturgical language of the Ethiopian and Eritrean Orthodox Churches. Other writing systems have also been used over the years by different Ethiopian communities. The latter include Sheikh Bakri Sapalo's script for Oromo.
According to the 2007 Ethiopian census, the largest first languages are: Oromigna 24,929,268 speakers or 33.8% of the total population; Amharic 21,631,370 or 29.33% (official language); Somali 4,609,274 or 6.25%; Tigrinya 4,324,476 or 5.86%; Sidamo 2,981,471 or 4.84%; Wolaytta 1,627,784 or 2.21%; Gurage 1,481,783 or 2.01%; and Afar 1,281,278 or 1.74%. Widely spoken foreign languages include English (major foreign language taught in schools), Arabic and Italian.
In Ethiopia, the term "Nilotic" is often used to refer to Nilo-Saharan languages and their communities. However, in academic linguistics, "Nilotic" is only part of "Nilo-Saharan", a segment of the larger Nilo-Saharan family.
A number of Ethiopian languages are endangered: they may not be spoken in one or two generations and may become extinct, victims of language death, as Weyto, Gafat, and Mesmes have and Ongota very soon will. The factors that contribute to language death are complex, so it is not easy to estimate which or how many languages are most vulnerable. Hudson wrote, "Assuming that a language with fewer than 10,000 speakers is endangered, or likely to become extinct within a generation", there are 22 endangered languages in Ethiopia (1999:96). However, a number of Ethiopian languages never have had populations even that high, so it is not clear that this is an appropriate way to calculate the number of endangered languages in Ethiopia. The real number may be lower or higher. The new language policies after the 1991 revolution have strengthened the use of a number of languages. Publications specifically about endangered languages in Ethiopia include: Appleyard (1998), Hayward (1988), Zelealem (1998a,b, 2004)
