Oromo people

The Oromo people (Oromo:Oromoo; Ge'ez:ኦሮሞ; ’Oromo) are an ethnic group inhabiting Ethiopia, northern Kenya, and parts of Somalia. With around 38 million members, they constitute the single largest ethnicity in Ethiopia and the wider Horn of Africa, at approximately 40% of Ethiopia's population according to the 2015 census. Oromos speak the Oromo language as a mother tongue (also called Afaan Oromoo and Oromiffa), which is part of the Cushitic branch of the Afro-Asiatic family. The name was given as Ilm’ Orma ("Sons of Men" or an eponymous 'Orma') in the 19th century; the present form is probably an obsolete plural of the same word orma ("person, stranger").
