Loss of innocence and a desire for innocence are two possible themes to write on. You could also write about adulthood as death, adulthood as a loss of identity, or simply the fear of adulthood.
Another option is to consider how Holden treats men and women differently. Who does he respect more? Who does he lie to more?
You could also discuss the symbols in the novel. These symbols include the hunting hat, the ducks, the baseball glove, the snowball, etc.
One possibility is to write about Holden's attitude toward purity and innocence. Compare is wanting to be a "Catcher in the Rye" with Robert Burns' poem "Coming thro' the Rye". How does Holden relate differently to children and adults?
A second option is to write about "truth". Who does Holden lie to and why are his lies significant? Does he care about the truth?
These are themes that my teacher gave us for our A.P summer reading but I think there is plenty to talk about for all of them:
The manifestation of loneliness,
The repercussion of lying and deception,
Alienation and depression
Sexuality and Intimacy
During my summer reading I was able to come up with more than 2 paragraphs worth of information for all these themes, so it should be easy to reach 2000 words.
I would say that the best and easiest theme to do an essay on from Catcher in the Rye would certainly be loss of innocence, especially considering the novel circulates around Holden growing up. You could talk about how Holden grows up, why he grows up, and his reaction to his newfound adulthood in the body of your essay.
But if I wrote about those topics it would tear a hole in the space/time continuem therefore causeing massive deaths.
lack of communication, dealing with change, or dealing with death?
