What is an epiphany in literature?

In literature, an epiphany refers to a moment of sudden revelation or insight experienced by a character. This pivotal moment often leads to a significant change in understanding or perspective for the character, illuminating deeper truths about themselves, their situation, or the world around them. Such moments can dramatically alter the course of the narrative or the character's development.

This concept is particularly important in storytelling, as it contributes to character growth and thematic depth. The sudden clarity gained during an epiphany can serve as a catalyst for personal transformation, driving the character's actions and decisions in the remainder of the story.

The other options describe different literary elements that do not encapsulate the essence of an epiphany. A gradual change in a character's personality refers to a slow evolution rather than an instantaneous realization. A brief exchange of dialogue lacks the introspective depth associated with an epiphany, while a lengthy backstory focuses on background information rather than immediate insight or revelation.
