The Songhay, Songhai or Ayneha languages are a group of closely related languages/dialects centred on the middle stretches of the Niger River in the West African countries of Mali, Niger, Benin, Burkina Faso and Nigeria. In particular, they are spoken in the cities of Timbuktu, Djenné, Niamey, Gao, Tillaberi, Dosso, Parakou, Kandi, Natitingou, Djougou, Malanville, Gorom-Gorom, In-Gall and Tabelbala. They have been widely used as a lingua franca in that region ever since the era of the Songhai Empire. In Mali, the government has officially adopted the dialect of Gao as the dialect to be used as a medium of primary education.
