Lingala (or Ngala, Lingala: Lingála) is a Bantu language spoken in the northwest of the Democratic Republic of the Congo, the northern half of the Republic of the Congo, in their capitals, Kinshasa and Brazzaville, and to a lesser degree as a trade language or because of emigration in neighbouring Angola or Central African Republic. Lingala has 20 million native speakers and about another 20 million second-language speakers, for an approximate total of 40 million speakers. A significant portion of both Congolese diasporas speaks Lingala in their countries of immigration like Belgium, France or the United States. Source: Wikipedia (en)
