In the short story "The Necklace" by Guy De Maupassant, the authors sketches for us the development of a dynamic character in Mathilde Loisel. When we first heasr about her, there is nothing much there - just a sketchily drawn, vague character who thinks she is cut out for better in her life - she wishes to be more than just a clerk. Then De Maupassant sets about filling her in with detail, we learn what is in her heart and mind (she feels she has a dull, ambition-less unsocialble existence.) Then, something happens to her and we see some dynamism. She gets an invitation to attend a ball with her husband, and her character starts to move forward, thinking quickly and making plans. Her plans to 'borrow' a fancy necklace however, go badly awry, and by the end of the story she has paid back an imagined debt and developed her character.
Mathilde in "The Necklace" is a dynamic character. Whether you judge her negatively before she loses the necklace (as greedy and selfish, etc.) or if you view her with more understanding (a frustrated artist-type), she still undergoes significant change after she loses the necklace.
Being a woman in a man's world, she does not have much earning power, but she puts what she has to use, cuts expenses, and spends ten years repaying the debt. When she happens upon the friend that originally lent her the necklace, Mathilde
...smiled with proud and childish joy.
Working and scraping by and working some more is not something Mathilde would have been proud of ten years earlier. She certainly is a dynamic character.
I agree that Mathilde is a dramatic character. In literature a dramatic character is one who undergoes change. In the beginning of the story Mathilde seems selfish and desiring to live beyond her means. She is upset because she can not attend the event without a nice necklace.
After Mathilde loses the necklace she and her husband must work themselves long and hard to pay back the money for the replacement necklace that she had bought. At the end of the story she has self-pride at her own accomplishment and she no longer feels the need to have such extravagant things. The price that she had paid for the one necklace had been too great a price.
dynamic can change into various things..
