How does Elizabeth view herself in society?

Her honesty, virtue, and lively wit enable her to rise above the nonsense and bad behavior that pervade her class-bound and often spiteful society.

Marriage is the ultimate goal, courtship constitutes the real working-out of love. Courtship becomes a sort of forge of a person’s personality, and each courtship becomes a microcosm for different sorts of love (or different ways to abuse love as a means to social advancement).

Whereas Elizabeth is an idealist who will not marry solely for money, to either a fool (Collins) or a man she dislikes (Darcy, at first), Charlotte, six years older than her friend and lacking a fortune, is a pragmatist: she must capitalize on any opportunity that presents itself in order to avoid the societal scorn that accompanies old maid status. As Austen says of Charlotte: she “accepted [Mr. Collins] solely from the pure and disinterested desire of an establishment.”
Though social strictures on marriage might be illogical and unromantic, were she to break them she would be negatively affecting her family.

The only individual who dares to stand up to the haughty Lady Catherine is Elizabeth (unsurprisingly, as elsewhere she sees through the pretensions of pompous and arrogant people like Mr. Collins and Miss Bingley). When Lady Catherine criticizes the Bennet sisters’ upbringing, Elizabeth defends her family, “suspect[ing] herself to be the first creature who had ever dared to trifle with so much dignified impertinence.”

The clunky language with which the narrator summarizes Elizabeth’s acceptance serves a specific purpose, as it captures the one moment of joyful incoherence for this supremely well-spoken character. She accepts Darcy’s proposal “immediately,” the narrator relates, but “not very fluently.” As Elizabeth allows herself to admit that her love has supplanted her long-standing prejudice, her control of language breaks down. The reader is left to imagine, with some delight, the ever-clever Elizabeth fumbling for words to express her irrepressible happiness.
