" 'You're a fool nigger, and the worst day's work Pa ever did was to buy you,' said Scarlett slowly. ... There, she thought, I've said 'nigger' and Mother wouldn't like that at all." [Margaret Mitchell, "Gone With the Wind," 1936]Used in combinations (e.g. nigger-brown, nigger-head, nigger-toe) since 1840s for various dark brown or black hues or objects; euphemistic substitutions (e.g. Zulu) began to appear in these senses c.1917.
