Data from virgin forest (4)
I believe the answer is:
info
'data' is the definition.
(thesaurus)
'from virgin forest' is the wordplay.
'from' says the answer is hidden in the clue.
'INFO' is hidden in the letters of 'virgin forest'.
(Other definitions for info that I've seen before include "Facts (abbr)" , "Intelligence (abbr)" , "Facts; knowledge gained" , "Dope" , "Data (abbrev.)" .)
