What purpose does a metaphor serve in literature?

A metaphor serves to draw a comparison between two unrelated things, which allows for a deeper understanding of an idea or concept by linking it to something familiar. This literary device enhances the meaning of the text by encouraging readers to think beyond the literal interpretation of words. For instance, when a writer compares a person to a storm, it conveys emotions and characteristics in a vivid way, suggesting intensity or turmoil without explicitly stating so.

Metaphors enrich the language and provide insight into themes and emotions by encouraging readers to make connections and interpretations that elevate the overall reading experience. This creative engagement often broadens the reader's perspective and invites them to reflect on the underlying message or emotion conveyed by the comparison.
