In chapter 10 with what term does Tom refer to himself? Why does Twain use quotation marks? Discuss the use of this term by wishes versus blacks. How is it the same/different

Tom refers to himself as a "nigger",

" Then he laid himself heavily down again, with a groan and the muttered words, "A nigger! I am a nigger! Oh, I wish I was dead!"

Tom is actually saying this to himself to illustrate the constant conflict he feels about his identity. Your last question is complex. This is only a short-answer forum and your last question is too detailed for this space.
