Wolof (ˈwoʊlɒf; Wolof làkk, وࣷلࣷفْ لࣵکّ) is a language of Senegal, Mauritania, and the Gambia, and the native language of the Wolof people. Like the neighbouring languages Serer and Fula, it belongs to the Senegambian branch of the Niger–Congo language family. Unlike most other languages of the Niger-Congo family, Wolof is not a tonal language.
Wolof is the most widely spoken language in Senegal, spoken natively by the Wolof people (40% of the population) but also by most other Senegalese as a second language. Wolof dialects vary geographically and between rural and urban areas. The principal dialect of Dakar, for instance, is an urban mixture of Wolof, French, and Arabic.
Wolof is the standard spelling and may also refer to the Wolof ethnicity or culture. Variants include the older French Ouolof, Jollof, or Jolof, which now typically refers either to the Jolof Empire or to jollof rice, a common West African rice dish. Now-archaic forms include Volof and Olof.
English is believed to have adopted some Wolof loanwords, such as banana, via Spanish or Portuguese, and nyam, used also in Spanish: 'ñam' as an onomatopoeia for eating or chewing, in several Caribbean English Creoles meaning "to eat" (compare Seychellois Creole nyanmnyanm, also meaning "to eat").
Wolof is spoken by more than 10 million people and about 40 percent (approximately 5 million people) of Senegal's population speak Wolof as their native language. Increased mobility, and especially the growth of the capital Dakar, created the need for a common language: today, an additional 40 percent of the population speak Wolof as a second or acquired language. In the whole region from Dakar to Saint-Louis, and also west and southwest of Kaolack, Wolof is spoken by the vast majority of people. Typically when various ethnic groups in Senegal come together in cities and towns, they speak Wolof. It is therefore spoken in almost every regional and departmental capital in Senegal. Nevertheless, the official language of Senegal is French.
