Shopping area one raced around (6)
I believe the answer is:
arcade
'shopping area' is the definition.
(I've seen this in another clue)
'one raced around' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'around' indicates an anagram.
'raced' is an anagram of 'rcade'.
'a'+'rcade'='ARCADE'
(Other definitions for arcade that I've seen before include "Arched passageway between shops" , "Shopping passage" , "Covered way with shops on either side" , "area of gaming" , "games area?" .)
