Divorce somewhere in Croatia (5)
I believe the answer is:
split
I believe this clue is a double definition.
'divorce' is the first definition.
(I've seen this before)
'somewhere in croatia' is the second definition.
(Croatian city)
(Other definitions for split that I've seen before include "Cut, cleft" , "Divide - Croatian port" , "European resort" , "Tear" , "Croatian resort; rend" .)
