Languages

French is the official language, spoken by all those who have spent several years in the educational system, in which French is used as the medium of instruction (Koranic schools are also popular, but Arabic is less widely spoken outside of the context of recitation). Overall, speakers of French were estimated to make up 26% of the population in 2022. During the 15th century, many European territories started to engage in trade in Senegal. In the 19th century, France increased its colonial influence in Senegal and thus the number of French-speaking people multiplied continuously. French was ratified as the official language of Senegal in 1960 when the country achieved independence.

Most people also speak their own ethnic language while, especially in Dakar, Wolof is the lingua franca. Pulaar is spoken by the Fulas and Toucouleur. The Serer language is widely spoken by both Serers and non-Serers (including President Sall, whose wife is Serer); so are the Cangin languages, whose speakers are ethnically Serers. Jola languages are widely spoken in the Casamance. Overall Senegal is home to around 39 distinct languages. Several have the legal status of " national languages ": Balanta-Ganja, Arabic, Jola-Fonyi, Mandinka, Mandjak, Mankanya, Noon (Serer-Noon), Pulaar, Serer, Soninke, and Wolof.

English is taught as a foreign language in secondary schools and many graduate school programs, and it is the only subject matter that has a special office in the Ministry of Education. Dakar hosts a couple of Bilingual schools which offer 50% of their syllabus in English. The Senegalese American Bilingual School (SABS), Yavuz Selim, and The West African College of the Atlantic (WACA) train thousands of fluent English speakers in four-year programs. English is widely used by the scientific community and in business, including by the Modou-Modou (illiterate, self-taught businessmen).

Portuguese Creole, locally known as Portuguese, is a prominent minority language in Ziguinchor, regional capital of the Casamance, spoken by local Portuguese creoles and immigrants from Guinea-Bissau. The local Cape Verdean community speak a similar Portuguese creole, Cape Verdean Creole, and standard Portuguese. Portuguese was introduced in Senegal's secondary education in 1961 in Dakar by the country's first president, Léopold Sédar Senghor. It is currently available in most of Senegal and in higher education. It is especially prevalent in Casamance as it relates with the local cultural identity.

A variety of immigrant languages are spoken, such as Bambara (70,000), Mooré (37,000), Kabuverdiano (34,000), Krio (6,100), Vietnamese (2,500), and Portuguese (1,700), mostly in Dakar.

While French is the sole official language, a rising Senegalese linguistic nationalist movement supports the integration of Wolof, the common vernacular language of the country, into the national constitution.

Senegalese regions of Dakar, Diourbel, Fatick, Kaffrine, Kaolack, Kedougou, Kolda, Louga, Matam, Saint-Louis, Sedhiou, Tambacounda, Thies and Ziguinchor are members of the International Association of Francophone regions.
