Drama set around middle of Flemish city (9)
I believe the answer is:
amsterdam
'city' is the definition.
(Amsterdam is an example)
'drama set around middle of flemish' is the wordplay.
'around' is an anagram indicator.
'middle of' says to take the centre.
The middle of 'flemish' is 'm'.
'drama'+'set'='dramaset'
'dramaset' with letters rearranged gives 'amsterda'.
'amsterda'+'m'='AMSTERDAM'
(Other definitions for amsterdam that I've seen before include "Dutch city of canals" , "Dutch capital" , "European capital" , "Western European city, a major diamond centre" , "9/11 [OLYMPIC VENUE]" .)
