French is the national language and the lingua franca between ethnic groups. Virtually no English is spoken in the whole of the country, aside from business offices and major banks in the capital.
Ewe is far and away the most widely spoken native language, with the Ewe people populating the southern half of the country. You may also come across the related Mina language in the area around Aneho. Kabiyè is the predominant language of the north.
