Laughter in literature serves as a powerful tool for both entertainment and social commentary. Authors often use humor to engage readers, lighten serious themes, or critique societal norms. Works like Mark Twain's "The Adventures of Huckleberry Finn" showcase how humor can highlight moral dilemmas and human folly. Additionally, laughter can create a sense of connection between characters and readers. Comedic elements in literature, such as witty dialogue or absurd situations, invite readers to share in the joy of the narrative. This shared laughter can enhance emotional resonance, making stories more memorable and impactful.
