Nigger

It is also in use with a more neutral meaning among African Americans, primarily as nigga.

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". Over time it took on a derogatory connotation 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.
