The word 丛林 is formed by combining two characters, each contributing to a unified visual and conceptual idea. 丛 (cóng) depicts things gathering or clustering together, like plants in a thicket, conveying density and entanglement. 林 (lín) represents a forest or a grove of trees. When placed side-by-side, they sequentially build upon each other to create the intensified image of a dense, tangled, and wild forest, essentially, a jungle, where the clustering quality of 丛 directly modifies and enhances the forest concept of 林.
