Sheltered, cloistered (8)
I believe the answer is:
secluded
I believe this clue is a double definition.
'sheltered' is the first definition.
(thesaurus)
'cloistered' is the second definition.
(I know that cloistered can be written as secluded)
(Other definitions for secluded that I've seen before include "Out of sight - away from society" , "Out of the way" , "Quiet and private" , "Sheltered and private" , "Hidden from general view" .)
