In the English language, the word ni**er is an ethnic slur used against black people, especially African Americans. Because it is considered extremely offensive, even if only mentioned and not used as a slur, it is often referred to by the euphemism "the N-word". It also may be used casually and fraternally among African Americans, primarily as n**ga.
The word originated in the 18th century as an adaptation of the Spanish word negro, a descendant of the Latin adjective niger, which means "black".[1] Over time it took on a derogatory connotation[2] and became a racist insult by the 20th century. Accordingly, it began to disappear from general popular culture. Its inclusion in classic works of literature has sparked controversy and ongoing debate.
