What is the purpose of similes in literature?

Similes serve the purpose of creating vivid imagery by comparing two different things using "like" or "as." This figurative language enriches the text by making descriptions more relatable and engaging for the reader. For instance, when an author writes, “Her smile was like the sun,” it helps readers visualize the warmth and brightness of the character's smile in a more immediate and impactful way than a straightforward description would. This tool enhances emotional resonance and allows readers to make connections between disparate concepts or experiences, enriching their understanding and appreciation of the narrative. The use of similes can also evoke feelings and memories, making the reading experience more immersive.
