At least 70 different languages are spoken in Ethiopia. Most of these belong to the Semitic, Cushitic, and Omotic divisions of the Afro-Asiatic linguistic family. Amharic, the official national language, is a Semitic tongue, the native language of perhaps 30% of the people. Tigrinya and Tigray, also Semitic, are spoken in the north. Orominga, a Cushitic tongue, is widely spoken in the south, perhaps by 40% of all Ethiopians. Somali and Afar, also Cushitic languages, are spoken in the east. Omotic tongues are spoken in the southwest. Nilo-Saharan language speakers live in the far southwest and along the western border. English is the principal second language taught in schools.
