Wherein to be sheltered, if only outwardly (4)
I believe the answer is:
shed
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for shed that I've seen before include "storage unit" , "Discard; small building" , "Outhouse for storing garden tools etc" , "place for bikes" , "Slough - outbuilding" .)
