A jungle is a tropical forest with luxuriant, tangled, impenetrable vegetation, generally teeming with wildlife.
It is popularly associated with the tropics.
Before the 1970s, tropical rainforests were generally referred to as jungles, but this terminology has fallen out of usage.
A jungle is a descriptive term, not a scientific one. It is generally used to refer to land overgrown with dense, tangled vegetation.
