Souk shopper (4)
I believe the answer is:
arab
'souk shopper' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arab that I've seen before include "Saudi or Omani, perhaps" , "race" , "Saudi, perhaps - breed of horse" , "Small, lively breed of horse" , "Saudi, e.g." .)
