Fruity footnote about a listener (5)
I believe the answer is:
pears
'fruity footnote about a listener' is the definition.
I can't tell whether this defines the answer.
'footnote about a listener' is the wordplay.
'footnote' becomes 'PS'.
'about' is an insertion indicator.
'a listener' becomes 'ear' (body part which hears or listens).
'ps' enclosing 'ear' is 'PEARS'.
Can you help me to learn more?
(Other definitions for pears that I've seen before include "Sweet juicy fruits" , "Fruit trees" , "Juicy fruits - spare them" , "Fruit - singer with ..." .)
