A symbol is an object used to stand for something else. Symbolism has a hidden meaning lying within it; these meanings unite to form a more detailed theme.

As the boy's jealousy focuses on the attention gained by a nondescript but persistent dog, Donoso leads us into the realm of multiple symbolism.
