Paradise inside protected enclave (4)
I believe the answer is:
eden
'paradise' is the definition.
(synonyms)
'inside protected enclave' is the wordplay.
'inside' indicates the answer is hidden within the clue.
'EDEN' can be found hidden inside 'protected enclave'.
(Other definitions for eden that I've seen before include "River - garden" , "Anthony ---, PM 1955" , "Genesis garden" , "Delightful place" , "Genesis location" .)
