Struggle to get girl back in city (6)
I believe the answer is:
vienna
'city' is the definition.
(I know that Vienna is a city)
'struggle to get girl back' is the wordplay.
'struggle' becomes 'vie' (to vie is to struggle or contend with).
'to get' says to put letters next to each other.
'girl' becomes 'ann' (woman's name).
'back' shows that the letters should be reversed in order.
'ann' written backwards gives 'nna'.
'vie'+'nna'='VIENNA'
'in' acts as a link.
(Other definitions for vienna that I've seen before include "Wien" , "Adult home of Beethoven, Brahms, Mozart and Schubert" , "Strauss 'Tales from the . . . . . . Woods'" , "Capital city on the Danube" , "Austrian capital" .)
