Abstract
The starting point of this research is the significant drop of the local languages speakers number in some south Africa countries and the will to show the importance of these languages in the buildind of this continent elites. In the sociolinguistic field, particulary in ivorian and beninese contexts and with quantitative and qualitative approach we have tried to answer these questions : what was the local languages role in the formation of these countries managers ? What is the situation of these languages learning nowadays ? What could motivate peoples to continuous their learning ? This investigation made with Ivorian and Beninese public (200 persons) allowed us to know, for exemple, that local languages, despite they important role in the elites formation, are relayed to the supporting role.
