The author looks at Jane Austen's use of language in this fascinating book - fascinating that is for anyone who enjoys Jane Austen's writing. She illustrates Austen's use of words by plentiful quotations from the texts of the novels. What I found most useful was the information about how the meanings of words have changed since the early nineteenth century.
Some of the words examined are, Sense, Sensibility and Sentiment; Gentility; Propriety and Decorum as well as Air and Address and Reason and Feeling. The author, in the process of looking at Jane Austen's language also looks at some of the main characters in the novels and gave me food for thought over some of the characters.
What I've always liked about Jane Austen's novels is that however many times you read them you can still see something new every time you read them. Reading books like this which examine the novels in details also helps me to see things in the novels from a different perspective. There is also a useful bibliography at the end of the book.
