New Orleans? (7)
I believe the answer is:
salerno
'new orleans?' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'new orleans?' is the wordplay.
'new' indicates anagramming the letters.
'orleans' with letters rearranged gives 'SALERNO'.
Can you help me to learn more?
(Other definitions for salerno that I've seen before include "in Italy!" , "South Italian port" , "European city!" , "Orleans (anag) - Italian port" , "Italian city; Orleans (anag.)" .)
