Although French is the official language of Senegal, many Senegalese citizens do not speak French, particularly in rural locations like Keur Momar Sarr. In rural areas, people tend to speak their maternal languages at home with their families. Some of these languages, including Mandingué, Bambara, and Balanta, are minority languages that are not represented by the Senegalese government as national languages. For those minority language speakers who do business outside of their villages, a vehicular language is often utilized for the purposes of communication and commerce.
Generally speaking, Wolof is the preferred vehicular language in northern Senegal (the part of Senegal north of the Gambia), and Dioula is the preferred vehicular language in southern Senegal (the part of Senegal south of the Gambia), although other languages like Serer, Pular, Malinké, and Soninké are preferred in specific subregions.

It will not be possible to alphabetize West-Africa as long as primary education remains in French. La Francophonie is chiefly about pressuring third-world governments into ramming the French language down their populace's collective throat even at the cost of development.
Indeed, local language instruction is deemed by many to be a prerequisite to alphabetization and development in Africa. It is, therefore, a promising sign to see primary instruction gradually shifting away from French in countries such as Senegal.
