Saving Italy's capital, or one of its capitals (4)
I believe the answer is:
bari
'one of its capitals' is the definition.
I can't judge whether this definition defines the answer.
'saving italy's capital' is the wordplay.
'saving' becomes 'bar' (I've seen this before).
'capital' says to take the initial letters.
The first letter of 'italys' is 'i'.
'bar'+'i'='BARI'
'or' acts as a link.
(Other definitions for bari that I've seen before include "Adriatic resort" , "Adriatic seaport" , "Adriatic port" .)
