The word “nigger” appears in the book 212 times. However, in the words of Russell Baker:
“The people whom Huck and Jim encounter on the Mississippi are drunkards, murderers, bullies, swindlers, lynches, thieves, liars, frauds, child abusers, numbskulls, hypocrites, windbags and traders in human flesh. All are white. The one man of honor in this phantasmagoria is ‘Nigger Jim,’ as Twain called him to emphasize the irony of a society in which the only true gentleman was held beneath contempt.”
