These 10 words describe the gap between appearance and reality that defines The Great Gatsby, from Gatsby's ostentatious parties to the illusions he builds around Daisy. Nearly every word on this list describes either a performance of wealth (ostentatious, extravagant, nouveau riche) or the moral cost hidden underneath it (decadence, corruption, disillusionment). Learning these words in context makes them easier to recall on both a literature exam and the SAT, since terms like illusion, cynical, and disillusionment appear constantly in AP Lit essay prompts.

Ostentatious

Designed specifically to impress or attract notice, showy on purpose.

Extravagant

Lacking restraint in spending, going beyond what is reasonable.

Tip: Gatsby's mansion is ostentatious because it is built to be seen and admired. His parties are extravagant because of the sheer scale of spending, orchestras, food, and endless champagne, regardless of who notices.

Commonly Confused · Belief vs. Losing It

Illusion

A false idea or belief that produces a false impression of reality.

Disillusionment

The disappointment that comes from discovering an illusion was never true.

Tip: Gatsby lives inside an illusion about Daisy for five years. Nick's disillusionment at the end of the novel is what happens when that kind of illusion finally breaks.

Cynical

Believing people are motivated purely by self-interest, distrustful of sincerity.

Nouveau Riche

Recently acquired wealth that lacks the social refinement of old money.

Tip: Jordan Baker's cynicism is a personality trait, how she sees everyone's motives. Gatsby being nouveau riche is a social fact about his money, no matter how genuine his own motives are.

Answer Key & Explanations

1Ostentatious. A mansion built as a tasteless imitation designed to attract attention rather than for genuine enjoyment is exactly what ostentatious describes.

2Extravagant. Orchestras, catered food, and champagne flowing all night for hundreds of uninvited guests describes spending far beyond reason, which is extravagance.

3Illusion. Falling in love with an idealized version of a person that no real person could match means building a life around an illusion, not simple obsession.

4Careless. Destroying lives and feeling no responsibility for the wreckage left behind describes carelessness, distinct from being simply cynical or corrupt.

5Cynical. Assuming everyone else is as dishonest as she is describes Jordan's cynicism, a distrust of others' sincerity.

6Decadence. Moral and cultural decline through excessive luxury and pleasure, contrasted with the Valley of Ashes, is exactly what decadence names.

7Nouveau Riche. Wealth that is new and unable to buy real social acceptance from old aristocracy describes being nouveau riche.

8Obsession. Being blinded to reality by an unhealthy fixation on winning Daisy back is obsession, not simple illusion.

9Corruption. Wealth built on bootlegging and organized crime, in service of an idealistic dream, is exactly what makes it ironic corruption.

10Disillusionment. Nick's final break with the wealthy class, driving him back to the Midwest, is disillusionment: discovering that what he believed was not what it seemed.
