Divorces in European city beginning to soar (6)
I believe the answer is:
splits
'divorces' is the definition.
(split can mean a divorce)
'european city beginning to soar' is the wordplay.
'european city' becomes 'split' (Croatian city).
'beginning to' says to take the initial letters.
The initial letter of 'soar' is 's'.
'split'+'s'='SPLITS'
'in' acts as a link.
(Other definitions for splits that I've seen before include "Comes or tears apart" , "Acrobatic feat -- schisms" , "Cleaves or divides" , "Separates or cuts with a sharp tool" , "Cracks" .)
