Ghana is a multilingual country in which about eighty languages are spoken. Of these, English, which was inherited from the colonial era, is the official language and lingua franca. Of the languages indigenous to Ghana, Akan is the most widely spoken in the south. Dagbani, Dagare, Sisaala, Waale, and Gonja are among the most widely spoken in the northern part of the country.
Ghana has more than seventy ethnic groups, each with its own distinct language. Languages that belong to the same ethnic group are usually mutually intelligible. The Dagbanli, Nanumba and Mamprusi languages of Northern Region, are almost the same and, are mutually intelligible with the Frafra and Waali languages of the Upper East and Upper West Regions of Ghana. The Mole–Dagbani languages are spoken by more than 20% of the population.
