Where airs were arranged for piano at the Moulin Rouge (5)
I believe the answer is:
paris
'where airs were arranged for piano at the moulin rouge' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'where airs were arranged for piano' is the wordplay.
I cannot really understand how this works, but
an anagram of 'airs' is 'aris' which is located in the answer.
'piano' could be 'p' (musical abbreviation) and 'p' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for paris that I've seen before include "foreign city" , "City on the Seine" , "Arc de Triomphe city" , "Eiffel Tower city" , "Continental capital" .)
