Mandinka is a Mande language with about 1.3 million speakers in Mali, Senegal, the Gambia, Guinea, Ivory Coast, Burkina Faso, Sierra Leone, Liberia, Guinea-Bissau and Chad. It is the main language of Gambia, and is recognised as a minority language in Senegal.
There are versions of the Latin and Arabic scripts for writing Mandinka. The Latin script is official, but the Arabic script is used by more people, and is older. The N'Ko script is also used in north east Guinea and in neighbouring parts of Ivory Coast and Mali.
Long vowels are indicated by doubling, e.g. aa, ee, etc.
