Rent somewhere in Croatia (5)
I believe the answer is:
split
This clue is a double definition.
'rent' is the first definition.
(rent can mean split or torn)
'somewhere in croatia' is the second definition.
(Croatian city)
(Other definitions for split that I've seen before include "run away" , "Divide into portions" , "somewhere on the Adriatic?" , "Break open suddenly" , "Balkan town" .)
