Why did Jane Austen name Pride and Prejudice Pride and Prejudice?
Originally titled First Impressions, Jane Austen changed the name of her ever enduring novel to Pride and Prejudice after a recommendation from her publisher. She had great success with her first published novel, Sense and Sensibility, and get publisher wanted her next novel to cash in on that popularity. By having the title follow the same naming convention, they believed her novel would be an instant success.
I don't think any of them could have envisioned just how successful the novel would become.
