Belgian city described by Edinburgh entrepreneur (5)
I believe the answer is:
ghent
'belgian city' is the definition.
(I've seen this before)
'described by edinburgh entrepreneur' is the wordplay.
'described by' says the answer is hidden in the clue.
'GHENT' can be found hidden inside 'edinburgh entrepreneur'.
(Other definitions for ghent that I've seen before include "European city" , "Belgian port" , "City of northwest Belgium, known for its cloth industry" , "Belgian city (from which the "good news" was brought to Aix)" , "source of good news" .)
