Although English is the official language used in schools, courts of law, and the administration, local languages are widely spoken.
While Wolof serves as a lingua-franca in the urban areas, Mandinka predominates in the rural areas. Fula, Jola, Serahuli, and other languages are often heard. One may also hear a mixture of English spoken with the local languages in the urban areas. This is a creole spoken by Akus.

Many Gambians speak several of these local languages in addition to English. It should not be assumed however, that English is thoroughly understood by Gambians outside official and professional circles (e.g., taxi drivers, merchants, domestic helpers).
A foreigner can certainly manage without knowing any of the local languages, but basic conversational skill in Mandinka or Wolof will prove to be a valuable investment in one’s living or working experience in The Gambia.
Indeed, only a few words in a local language will go a long way towards enhancing the quality of interactions with Gambians and will open many doors.
