The charm of a very quiet part of Ealing (6)
I believe the answer is:
appeal
'the charm' is the definition.
('appeal' can be a synonym of 'charm')
'a very quiet part of ealing' is the wordplay.
'very quiet' becomes 'pp' (musical abbreviation for pianissimo).
'part of ealing' becomes 'eal' (I can't explain this - if you can you should believe this answer much more).
'a'+'pp'+'eal'='APPEAL'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for appeal that I've seen before include "Plea" , "Claim - fascination" , "Petition or attraction" , "Seek to have verdict overturned" , "Petition to a higher court" .)
