3. character in the Great Gatsby

Daisy Fay Buchanan fits the definition of her name. Fitzgerald’s characterization of Daisy matches with the meaning of the flower, she’s bright, cheerful and beautiful.

Daisy as she grows up realizes the status of women back in the 20s. She can be of old money; rich and beautiful. But despite that, her value is nothing unless she is paired with a rich man. Daisy calls herself a ‘beautiful little fool‘ because “that’s the best thing a girl can be in this world“. With this realization, she also becomes aware of what she can do.

While she might have been young and idealistic to have fallen for Jay Gatsby, the decision to marry Tom Buchanan was hers.

According to the definition, Daisy also symbolizes a new beginning. I would like to think that Gatsby saw that in Daisy.
