ed with dense forest and tangled vegetation, usually in tropical climates. Application of the term has varied greatly during the past recent century.


Etymology

The word ''jungle'' originates from the Sanskrit word ''jaṅgala'' (), meaning rough and arid. It came into the English language via Hindi in the 18th century. ''Jāṅgala'' has also been variously transcribed in English as ''jangal'', ''jangla'', ''jungal'', and ''juṅgala''. Although the Sanskrit word refers to dry land, it has been suggested that an Anglo-Indian interpretation led to its connotation as a dense "tangled thicket", while others have argued that a cognate word in Urdu derived from Persian, جنگل (Jangal), did refer to forests. The term is prevalent in many languages of the Indian subcontinent, and the Iranian Plateau, where it is commonly used to refer to the plant growth replacing

or to the unkempt tropical vegetation that takes over abandoned areas.


History

The jungle is the richest habitat on Earth. Over the intervals of time, different parts of tropical areas have provided a variety of flora and fauna, together with newer species discovered annually. Tropical jungles have been the home to indigenous peoples, who have shaped traditional cultures and civilizations based on the environment.

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. Typically such vegetation is sufficiently dense to hinder movement by humans, requiring that travellers cut their way through.Tropical Forests

and 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 mangroves are commonly referred to as jungles of this type. Having a more open canopy than rainforests, monsoon forests typically have dense understoreys with numerous

and low canopies of mangroves produce similar difficulties.


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 tropical forest.Purser, B. 2003. Jungle bugs: masters of camouflage and mimicry.

, temperate rainforest, and mangroves with no reference to the vegetation structure or the ease of travel. 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. Upton Sinclair gave the title '' The Jungle'' (1906) to his famous book about the life of workers at the Chicago Stockyards, portraying the workers as being mercilessly exploited with no legal or other lawful recourse. The term "

'' (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".

compared Israel to "a villa in the jungle", a comparison which had been often quoted in Israeli political debates. Barak's critics on the left side of Israeli politics strongly criticised the comparison. For example, Uri Avnery charged that comparing "civilised" Israel with "a villa" and Israel's Arab neighbors with the "wild beasts" of the "jungle" tends to throw the blame for the absence of peace on the "wild" Arab and Palestinian side, and absolve Israel of responsibility.Larry Derfner, "Ehud Barak to step down: On his de-evolution, and Israel's", +972 Magazine, November 26, 201
