What does the apple symbolize in Speak?

The apple in Speak is a symbol of temptation and forbidden knowledge. It represents the character Melinda's journey of self-discovery and her struggle to accept her own power. The apple appears throughout the novel, often in moments of crisis or change for Melinda. For example, she first encounters an apple when she is first raped at a party. Later, she sees apples when she is struggling with her depression and anxiety. Finally, she sees an apple when she is finally able to accept her own power and confront her attacker. The apple thus serves as a reminder of Melinda's journey and her growth throughout the novel.
