Save island community in southern Italy (4)
I believe the answer is:
bari
'community in southern italy' is the definition.
The definition suggests a singular noun which matches the answer.
'save island' is the wordplay.
'save' becomes 'bar' (both can mean 'except').
'island' becomes 'i' (geographical abbreviation).
'bar'+'i'='BARI'
Can you help me to learn more?
(Other definitions for bari that I've seen before include "Adriatic port" , "Adriatic seaport" , "Adriatic resort" .)
