Shut up in a store? (4)
I believe the answer is:
coop
I believe this is a double definition.
'shut up' is the first definition.
(thesaurus)
'a store?' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for coop that I've seen before include "Store" , "Pen" , "box of chickens" , "pound" , "Cage for poultry" .)
