What insight is given into elizas character and her life?

Eliza is the poor flower girl turned linguistic protégé. Headstrong and coarse street urchin taken into Professor Higgins care on a bet that he cannot transform her into the verisimilitude of a duchess. Liza is use to a life of poverty and survival. She is uneducated and considered "crude" by the upper class. Despite her rebellious nature, Eliza becomes fond of her teacher and is upset by his impartiality. She ends up marrying Freddy, a member of the middle class who worships her, and sets up a flower shop with him, successfully crossing class lines.
