A. the use of a word or object to represent something else
Explanation:
Another helpful definition of symbolism is 'a tangible object representing an abstract idea".
So, any object that is recurring and linked to an idea, is a symbol.
Symbolism is almost always an intentional addition by the author, because it helps the reader identify with key ideas or feelings that the author wants to convey.
For example the mocking jay pin in The Hunger Games can be linked to a couple ideas, such as freedom or the revolution.
