Gbe covers South-East Ghana (left bank of the Volta) and southern parts of Togo and Benin; the number of speakers is estimated at less than 10 million people.
For linguists, Gbe is a language of the Kwa group of which the main dialects are Ewe (about 3 million mainly in Togo and Ghana) followed by Fon (a little less than 2 million mainly in Benin) and Aja (1 million mainly in Benin).
However, the speakers of these different dialects often perceive them as distinct languages. Here, it is difficult to define the limits of a language continuum
