Austen reveals two of its primary themes: marriage and class. Individuals are defined by their marital opportunities and financial holdings. However, the irony in this line conceals an implicit criticism. The line's grammatical focus is on "a single man... in want of a wife", But Austen's Novel is centred on her female characters as they struggle to succeed within this oppressive patriarchy. Each Miss Bennet knows that without a husband of decent means and status, she risks living a life as a powerless and potentially destitute spinster.
