What is the significance of irony in literature?

Irony in literature is significant because it adds complexity and often highlights contradictions within the narrative. By presenting situations where the outcome differs from what is expected or where characters say one thing but mean another, irony deepens the reader's understanding of themes, character motivations, and societal norms. This complexity can provoke thought and encourage readers to engage with the text on a more profound level, revealing layers of meaning that might not be immediately apparent. Additionally, irony can reflect the disparities between reality and perception, enhancing the emotional and intellectual experience of the story.

The other options do not capture the multifaceted nature of irony. Predictable endings are typically contrary to irony, which is designed to create surprise or twist expectations. While irony may occasionally be used for comedic effect, its purposes expand far beyond just humor. Lastly, establishing setting is more commonly achieved through descriptive imagery and context rather than through the use of irony itself.
