Uncommitted lover on the loose around Cyprus (5-4)
I believe the answer is:
fancy-free
'uncommitted' is the definition.
(similar in meaning)
'lover on the loose around cyprus' is the wordplay.
'lover' becomes 'fan' (synonyms).
'on the loose' becomes 'free' (similar in meaning).
'around' is an insertion indicator.
'cyprus' becomes 'cy' (abbreviation).
'fan'+'free'='fanfree'
'fanfree' enclosing 'cy' is 'FANCY-FREE'.
(Other definitions for fancy-free that I've seen before include "Having no commitments" , "Lacking responsibility - not currently in love" , "With no emotional ties" .)
