The English word JUNGLE is from the Hindi word jangal (also Marathi), meaning a "forest, wasteland," which in turn is derived from Sanskrit jangala, "desert, uncultivated land."
The modern English sense of a "land overgrown with vegetation" dates to the 19th century, and the Oxford English Dictionary suspects that its evolution in English might be influenced by the word "tangle."
