In Chapter 11, Jane Austen and Emma’s sister, Isabella, both use formal language to address the other characters. Austen introduces the Knightley couple as “Mr. and Mrs. John Knightley,” instead of a less formal way, such as, “Emma’s sister and brother in law.” Isabella also address her father as, “sir.” Does this reveal the family’s distance? Does Austen intend to satirize by using this words? If so, what does she mean to satirize?
