It's a different place from Salerno (7)
I believe the answer is:
orleans
'it's a different place' is the definition.
I can't judge whether this defines the answer.
'from salerno' is the wordplay.
'from' is an anagram indicator (from the letters).
'salerno' anagrammed gives 'ORLEANS'.
Can you help me to learn more?
(Other definitions for orleans that I've seen before include "Joan of Arc was known as the Maid of . . . . . . ." , "French city on the Loire" , "European city" , "historic French city" , "City of north-central France" .)
