‘丛林’ (cóng lín) literally combines ‘丛’ (cóng), meaning ‘cluster’ or ‘thicket’, and ‘林’ (lín), meaning ‘grove’ or ‘forest’. Together, they evoke a dense, tangled, often wild expanse of trees and undergrowth—more impenetrable and untamed than a simple ‘forest’ (森林, sēn lín). It emphasizes lushness, vertical layering, and ecological complexity, frequently implying habitats for wildlife.

The term appears in ecological, literary, and travel contexts—especially when describing tropical or subtropical environments. Unlike ‘森林’, which can refer to managed or planted woodlands, ‘丛林’ carries a stronger connotation of natural wilderness, mystery, and vitality. It’s commonly used in nature documentaries, adventure narratives, and conservation discussions, and occasionally in metaphorical expressions like ‘城市丛林’ (urban jungle), though that phrase is usually borrowed from English and less common in native usage.
