Paradise in protected enclave (4)
I believe the answer is:
eden
'paradise' is the definition.
(Garden of Eden)
'in protected enclave' is the wordplay.
'in' says the answer is hidden in the clue.
'EDEN' can be found hidden inside 'protected enclave'.
(Other definitions for eden that I've seen before include "The first habitat" , "(Biblical) paradise" , "late PM" , "The primal garden" , "Unspoiled paradise" .)
