Authors use symbolism in their works to convey deeper meanings by using objects, characters, settings, and other elements to represent abstract ideas or themes. Symbolism allows authors to add layers of meaning to their writing, creating a more complex and multi-dimensional reading experience for the audience. By incorporating symbols, authors can subtly communicate deeper emotions, societal issues, philosophical concepts, or moral lessons that may not be explicitly stated in the text. This technique invites readers to engage more deeply with the text, encouraging them to uncover hidden meanings and interpret the story in a more profound way.
