A paradise for some jungle denizens (4)
I believe the answer is:
eden
'a paradise' is the definition.
(Garden of Eden)
'some jungle denizens' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'EDEN' is hidden in the letters of 'jungle denizens'.
'for' is the link.
(Other definitions for eden that I've seen before include "A Conservative PM" , "5,27 [PRIME MINISTER]" , "prime minister in the past" , "Unspoiled paradise" , "The near-perfect garden" .)
