A Raisin in the Sun is essentially about dreams, as the main characters struggle to deal with the oppressive circumstances that rule their lives. The title of the play references a conjecture that Langston Hughes famously posed in a poem he wrote about dreams that were forgotten or put off. He wonders whether those dreams shrivel up “like a raisin in the sun.” Every member of the Younger family has a separate, individual dream—Beneatha wants to become a doctor, for example, and Walter wants to have money so that he can afford things for his family. The Youngers struggle to attain these dreams throughout the play, and much of their happiness and depression is directly related to their attainment of, or failure to attain, these dreams. By the end of the play, they learn that the dream of a house is the most important dream because it unites the family.

The character of Mr. Lindner makes the theme of racial discrimination prominent in the plot as an issue that the Youngers cannot avoid. The governing body of the Youngers’ new neighborhood, the Clybourne Park Improvement Association, sends Mr. Lindner to persuade them not to move into the all-white Clybourne Park neighborhood. Mr. Lindner and the people he represents can only see the color of the Younger family’s skin, and his offer to bribe the -Youngers to keep them from moving threatens to tear apart the Younger family and the values for which it stands. Ultimately, the Youngers respond to this discrimination with defiance and strength. The play powerfully demonstrates that the way to deal with discrimination is to stand up to it and reassert one’s dignity in the face of it rather than allow it to pass unchecked.

The Youngers struggle socially and economically throughout the play but unite in the end to realize their dream of buying a house. Mama strongly believes in the importance of family, and she tries to teach this value to her family as she struggles to keep them together and functioning. Walter and Beneatha learn this lesson about family at the end of the play, when Walter must deal with the loss of the stolen insurance money and Beneatha denies Walter as a brother. Even facing such trauma, they come together to reject Mr. Lindner’s racist overtures. They are still strong individuals, but they are now -individuals who function as part of a family. When they begin to put the family and the family’s wishes before their own, they merge their individual dreams with the family’s overarching dream.

The Younger apartment is the only setting throughout the play, emphasizing the centrality of the home. The lighting seems to change with the mood, and with only one window, the apartment is a small, often dark area in which all the Youngers—at one time or another—feel cramped. While some of the play’s action occurs outside of the apartment, the audience sees this action play out in the household. Most of what happens outside of the apartment includes Travis’s playing out in the street with the rat and Walter’s drinking and delinquency from work. The home is a galvanizing force for the family, one that Mama sees as crucial to the family’s unity. The audience sees characters outside the family—Joseph Asagai, George Murchison, Mrs. Johnson, Mr. Lindner, and Bobo—only when they visit the apartment. These characters become real through their interactions with the Youngers and the Youngers’ reactions to them. The play ends, fittingly, when Mama, lagging behind, finally leaves the apartment.

This phrase appears early in the play, as an instruction from Ruth to Walter to quiet him. Walter then employs the phrase to illustrate how women keep men from achieving their goals—every time a man gets excited about something, he claims, a woman tries to temper his enthusiasm by telling him to eat his eggs. Being quiet and eating one’s eggs represents an acceptance of the adversity that Walter and the rest of the Youngers face in life. Walter believes that Ruth, who is making his eggs, keeps him from achieving his dream, and he argues that she should be more supportive of him. The eggs she makes every day symbolize her mechanical approach to supporting him. She provides him with nourishment, but always in the same, predictable way.

The most overt symbol in the play, Mama’s plant represents both Mama’s care and her dream for her family. In her first appearance onstage, she moves directly toward the plant to take care of it. She confesses that the plant never gets enough light or water, but she takes pride in how it nevertheless flourishes under her care. Her care for her plant is similar to her care for her children, unconditional and unending despite a less-than-perfect environment for growth. The plant also symbolizes her dream to own a house and, more specifically, to have a garden and a yard. With her plant, she practices her gardening skills. Her success with the plant helps her believe that she would be successful as a gardener. Her persistence and dedication to the plant fosters her hope that her dream may come true.

When the play begins, Beneatha has straightened hair. Midway through the play, after Asagai visits her and questions her hairstyle, she cuts her Caucasian-seeming hair. Her new, radical afro represents her embracing of her heritage. Beneatha’s cutting of her hair is a very powerful social statement, as she symbolically declares that natural is beautiful, prefiguring the 1960s cultural credo that black is beautiful. Rather than force her hair to conform to the style society dictates, Beneatha opts for a style that enables her to more easily reconcile her identity and her culture. Beneatha’s new hair is a symbol of her anti-assimilationist beliefs as well as her desire to shape her identity by looking back to her roots in Africa.
