Final answer:
Klipspringer, the disheveled man Nick sees at Gatsby's house in pajamas, is known as the 'boarder', a character representing the parasitic socialites of the 1920s in Fitzgerald's work.
Step-by-step explanation:
At Gatsby's house, Nick sees Klipspringer, a disheveled man dressed in pajamas, who is known as the 'boarder'. Klipspringer, the disheveled man Nick sees at Gatsby's house in pajamas, is known as the 'boarder', a character representing the parasitic socialites of the 1920s in Fitzgerald's work.
Klipspringer is a minor character in F. Scott Fitzgerald's The Great Gatsby, often depicted as a sort of permanent guest at Gatsby's mansion, presumably living off Gatsby's wealth without having a home of his own. Fitzgerald introduces characters such as Klipspringer to highlight the superficial and parasitic nature of the socialites during the 1920s.
He is not essential to the plot but is more a symbol of the era's decadence. Fitzgerald's works provide a sophisticated social satire of the time, portraying the rise and fall of characters like Jay Gatsby through the eyes of the narrator, in this case, Nick Carraway.
