Nigger

Nigger is a noun in the English language, most notable for its usage in a pejorative context to refer to black people, and also as an informal slang term, among other contexts. It is a common ethnic slur, usually directed at people of Sub-Saharan African descent and suggests that its target is extremely unsophisticated. The word originated as a term used in a neutral context to refer to black people, as a variation of the Spanish/Portuguese noun negro, a descendant of the Latin adjective niger ("color black").
