Made light of some food store (4)
I believe the answer is:
deli
'food store' is the definition.
(I've seen this in another clue)
'made light of some' is the wordplay.
'of some' indicates a hidden word (I've seen 'some' mean this).
'DELI' is hidden within 'made light'.
(Other definitions for deli that I've seen before include "Unusual food shop" , "Specialist food shop" , "Shop selling processed food products" , "Special shop" , "Specialist foodshop(abbr.)" .)
