Oromo language

Oromo, historically also called Galla, is an Afroasiatic language belonging to the Cushitic branch, primarily spoken by the Oromo people, native to the Ethiopian state of Oromia; and northern Kenya. It is used as a lingua franca in Oromia and northeastern Kenya. It is officially written in the Latin script, although traditional scripts are also informally used.

With more than 41.7 million speakers making up 33.8% of the total Ethiopian population, Oromo has the largest number of native speakers in Ethiopia, and ranks as the second most widely spoken language in Ethiopia by total number of speakers (including second-language speakers) following Amharic. Forms of Oromo are spoken as a first language by an additional half-million people in parts of northern and eastern Kenya. It is also spoken by smaller numbers of emigrants in other African countries such as South Africa, Libya, Egypt and Sudan. Oromo is the most widely spoken Cushitic language and among the five languages of Africa with the largest mother-tongue populations.

Oromo serves as one of the official working languages of Ethiopia and is also the working language of several of the states within the Ethiopian federal system including Oromia, Harari Region and Dire Dawa and Oromia in the Amhara Region. It is a language of primary education in Oromia, Harari, Dire Dawa, Benishangul-Gumuz Region, and Addis Ababa. It is used as an internet language for federal websites along with Tigrinya. Under Haile Selassie's government, Oromo was de facto banned in education, in conversation, and in administrative matters.
