Cuts damaged a big city somewhere in Italy (7)
I believe the answer is:
tuscany
'somewhere in italy' is the definition.
(I've seen this before)
'cuts damaged a big city' is the wordplay.
'damaged' is an anagram indicator.
'big city' becomes 'NY' (New York).
'cuts' anagrammed gives 'tusc'.
'tusc'+'a'+'ny'='TUSCANY'
(Other definitions for tuscany that I've seen before include "'Chiantishire'" , "Region of N Italy, capital Florence" , "Prosperous region of west-central Italy" , "Italian region, capital Florence" , "N. Italian region" .)
