Varying usage
As dense and tangled vegetation

One of the most common meanings of ''jungle'' is land overgrown with tangled vegetation at ground level, especially in the
tropics
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's ax ...
. Typically such vegetation is sufficiently dense to hinder movement by humans, requiring that travellers cut their way through.

'' and a ''jungle'', since the understorey of rainforests is typically open of vegetation due to a lack of sunlight, and hence relatively easy to traverse.
Jungles may exist within, or at the borders of, tropical forests in areas where the woodland has been opened through natural disturbance such as hurricanes, or through human activity such as logging.
The
successional vegetation that springs up following such disturbance, is dense and tangled and is a "typical" jungle. Jungle also typically forms along rainforest margins such as stream banks, once again due to the greater available light at ground level.
Monsoon forests and

As moist forest

Because European explorers initially travelled through tropical forests largely by river, the dense tangled vegetation lining the stream banks gave a misleading impression that such jungle conditions existed throughout the entire forest. As a result, it was wrongly assumed that the entire forest was impenetrable jungle. This in turn appears to have given rise to the second popular usage of jungle as virtually any humid

The terms "tropical forest" and "rainforest" have largely replaced "jungle" as the descriptor of humid tropical forests, a linguistic transition that has occurred since the 1970s. "Rainforest" itself did not appear in English dictionaries prior to the 1970s.
[Rogers, C. 2012 ''Jungle Fever: Exploring Madness and Medicine in Twentieth-Century Tropical Narratives''. Vanderbilt University Press, Nashville. .] The word "jungle" accounted for over 80% of the terms used to refer to tropical forests in print media prior to the 1970s; since then it has been steadily replaced by "rainforest",
[Slater, C (2003). In Search of the Rain Forest. Duke University Press] although "jungle" still remains in common use when referring to tropical rainforests.
As metaphor

As a metaphor, ''jungle'' often refers to situations that are unruly or lawless, or where the only law is perceived to be "survival of the fittest". This reflects the view of "city people" that forests are such places.

"The law of the jungle" (also called jungle law) is an expression that has come to describe a scenario where "anything goes". The ''Oxford English Dictionary'' defines the Law of the Jungle as "''the code of survival in jungle life'', now usuall ...
" is also used in a similar context, drawn from
Rudyard Kipling's ''
The Jungle Book'' (1894)—though in the society of jungle animals portrayed in that book and obviously meant as a metaphor for human society, that phrase referred to an intricate code of laws which Kipling describes in detail, and not at all to a lawless chaos.
The word "jungle" carries connotations of untamed and uncontrollable nature and isolation from civilisation, along with the emotions that evokes: threat, confusion, powerlessness, disorientation and immobilisation.
The change from "jungle" to "rainforest" as the preferred term for describing tropical forests has been a response to an increasing perception of these forests as fragile and spiritual places, a viewpoint not in keeping with the darker connotations of "jungle".
Cultural scholars, especially
post-colonial critics, often analyse the jungle within the concept of hierarchical domination and the demand western cultures often places on other cultures to conform to their standards of civilisation. For example:
