Grand centrepiece missing from garden shop (7)
I believe the answer is:
grocery
'shop' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for grocery that I've seen before include "Food shop" , "Kind of shop" , "Type of food store" , "Shop for footstuffs" , "Shop selling foodstuffs" .)
