Here's why:
* Symbolism is a literary device where a concrete object, person, place, or event represents something abstract or beyond its literal meaning.
* The concrete object acts as a symbol for the abstract idea or emotion.
For example:
* A rose is often used as a symbol of love.
* A dove is often used as a symbol of peace.
* A black cat is often used as a symbol of bad luck.
By using symbols, authors can add layers of meaning to their work and create a deeper understanding in the reader.
