Indeed, symbolism is noted as a literary device used by authors and writers where they use symbols, be it words, people, marks, locations, or abstract ideas to represent something beyond the literal meaning. It's quite magical, infusing a whole different depth into the narrative.
For instance, crows are often used to symbolize death, and spring is interpreted as a symbol of rebirth. This device, in essence, paints vibrant layers onto the canvas of a story, allowing the readers to dive deeper into understanding the heart of the story.
