Get payback for turning up to promote German city (6)
I believe the answer is:
geneva
'city' is the definition.
(Geneva is an example)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for geneva that I've seen before include "Convention site" , "Swiss lakeside city" , "Some bands" , "old Calvinist stronghold" , "Calvin's city" .)
