N*gger

"Nigger" was a pejorative and generally offensive word that meant African-American. Its insult was plain when seen in the context of typical speech by pro-slavery Colonel Jubal Eustace:
 * "You can't befriend a nigger! They're property.  No better than a plough or an ox!  Would you try to make friends with an ox?"

It was a word Peri Brown hated. It was also a word that she had heard was re-appropriated by the African-American community sometime after the 1980s. Nevertheless it was a word she despised.

Equally, the Fifth Doctor found the word "disgusting" and admonished Eustace not to use it. (PROSE: Blood and Hope)
