Second, the letter A also means amour which between Hester and Arthur Dimmesdale.The two one fell in love with each other when they met. And I think Hester is quite brave and royal. She has a deep love with Mr.Dimmesdale.If she could told people the name of the man who had the same sin as her, she will get a lighter punishment,but she refused to do so.She was royal to their amour and didn't afraid to face up other people's accusations and insults.After she received her public punishment, her time in prison came to end, but she did not move away from the town. She still stayed at the town where Arthur Dimmesdale lived in. So the letter A symbolizes the great amour between Hester ang Arthur.
