Salerno may be the home of jazz (3,7)
I believe the answer is:
new orleans
'the home of jazz' is the definition.
'salerno' is the wordplay.
I cannot quite see how this works, but
an anagram of 'salerno' is 'orleans' which is located in the answer.
The remaining letters 'new' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'may be' acts as a link.
Can you help me to learn more?
(Other definitions for new orleans that I've seen before include "port city in the south" , "US city" , "Devastated city" , "City of Louisiana" .)
