Capital, we hear, for food shop (4)
I believe the answer is:
deli
'for food shop' is the definition.
(short for delicatessen)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for deli that I've seen before include "Food shop (colloq.)" , "Food store" , "Specialist foodshop(abbr.)" , "Cold-meat counter" , "place to buy food" .)
