What has Eliza learned by the end of Pygmalion?
Obviously Eliza has learned how to be a lady by the end of the play--in spite of the boorish behavior of Henry Higgins. She understand all kinds of opportunities should be open to her, but she also knows she is now too well spoken for a humble flower shop, based on this class-conscious society. She also understands that speaking well, having money, and knowing the proper thing to say at the proper time do not mean a person has true class. Just look at her teacher! Finally, she understands she can't go back to being just a flower girl, and she won't.
