What are some of the literary devices and literary terminologies in the chapters 3-4 then 5-6, 7-8?I know it may seem like alot, however i am...

There are many.  One of the most prominent literary
devices at work in Fitzgerald's The Great Gatsby is symbolism.  The
narrator Nick continually refers to the green light that sits across the harbor near
Daisy's home.  Gatsby often looks out at this green light, and it symbolizes the hope of
opportunity that Gatsby has in regards to finally having a relationship with Daisy.  In
a broader context, the green light is symbolic of the American dream and its effects on
the characters in the novel.  They all in some way want to pursue a path that they
believe will bring them happiness, and the green light suggests that the characters'
willingness to pursue these dreams even in the face of dire
consequences.
