Other main languages are Tigrigna, Guraginya, Adarinya, Afan Oromo, Somalinya, Sidaminya, Afarinya, Gumuz, Berta and Anuak.
The Tigrigna- and Amharic-speaking people of the north and centre of the country are mainly agriculturalists, tilling the soil with ox-drawn ploughs and growing teff (a local millet), wheat, barley, maize and sorghum.
The differences may be observed in the number of languages spoken - an astonishing 83, falling into four main language groups: Semitic, Cushitic, Omotic and Nilo-Saharan. Regarding the country’s nations and nationalities, which is estimated to be over 90 million, the number of ethnic Oromo accounts about 34.5 % while Amhara (Amara) is 26.9%, Somali (Somalie) 6.2 %, Tigray (Tigrigna) 6.1%, Sidama 4%, Gurage 2.5%, Welaita 2.3%, Hadiya 1.7%, Afar (Affar) 1.7%, Gamo 1.5%, Gedeo 1.3%, other 11.3% (2007 Census).
The principle Semitic language spoken in the north-western and central part of the country is Amharic, which is also the official language of the modern state.
Living near the Omo River are the Mursi, well-known for the large clay discs that the women wear inserted in a slit in their lower lips.
