Literary devices are techniques that writers use to convey their messages, enhance their storytelling, and engage readers. These tools, such as metaphors, similes, and alliteration, help create vivid imagery and evoke emotions, making the text more impactful and memorable. By employing literary devices, authors can add depth to their narratives and characters. For instance, a metaphor can draw a powerful comparison between two unrelated things, allowing readers to see familiar concepts in a new light. Overall, these devices enrich the reading experience and invite deeper interpretation.
