Rome can appear in a new light as an Italian city (7)
I believe the answer is:
cremona
'italian city' is the definition.
(Cremona is a city in Italy)
'rome can appear' is the wordplay.
'appear' indicates an anagram.
'rome'+'can'='romecan'
'romecan' is an anagram of 'CREMONA'.
'in a new light as an' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for cremona that I've seen before include "where Stradivari made violins" , "here in Lombardy" , "Northern Italian city" , "Guarneri's place" , "...and the Italian home of both Stradivari and the Amatis" .)
