Proper ceremony for the listener (5)
I believe the answer is:
right
'proper' is the definition.
(I know that proper can be written as right)
'ceremony for the listener' is the wordplay.
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'for the listener' shows a homophone (sound like).
'rite' is a homophone of 'RIGHT'.
(Other definitions for right that I've seen before include "correctly" , "Privilege" , "The Tory side" , "Correct; political wing" , "Fair or just" .)
