What does the green light symbolize in the book?

In The Great Gatsby, the green light symbolizes Gatsby's hopes and dreams for the future, particularly his desire to reunite with Daisy Buchanan. It represents the idealized, elusive American Dream that Gatsby strives for—something just out of reach, full of promise but ultimately unattainable. Nick reflects on the green light as a symbol of both Gatsby's longing and the broader human pursuit of dreams.
