Mondele, or mundelé, (pl. mindele) is a Bobangi term meaning "white" (white man, not the color, mpembe) European-style person, person with light skin color. The words were originally used to describe Belgian and French colonists, but can be used to describe any light-skinned non-African.
According to the Lingala Online Dictionary "It seems that the origin of the word comes from the bobangi language
and that the radical "ndele" lets us believe that the african
perceived the european as someone who is insincere (="ndelengene")
rather than by his color."
The word can also be applied even to black Africans with a much lighter skin complexion, Coloureds, foreign-raised locals speaking with foreign accents, visiting expatriates, or westernised blacks (including African Americans), who are referred to specifically as mundele ndombe.
