||I heard recenntly that the word jungle originated from a word in the sanskrit language is this true|
Yes, but by way of Hindi. The Hindi word for forest is jangal which came from the Sanskrit, jangala, meaning, oddly enough, a desert area. It was assimilated into English during the British colonization of India (Webster's puts it at 1776).|
Incidentally, certain other words, like "pajamas" came from Hindi the same way, but owe their further origin to Persian (pa, "leg," and jama, "garment") rather than Sanskrit.
