A repeated cheer, awkward problem for listener (7)
I believe the answer is:
earache
'a repeated cheer' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'awkward problem for listener' is the wordplay.
'awkward problem' becomes 'ache' (I can't explain this - if you can you should give a lot more credence to this answer).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'listener' becomes 'ear' (body part which hears or listens).
'ache' put after 'ear' is 'EARACHE'.
Can you help me to learn more?
(Other definitions for earache that I've seen before include "Aural complaint" , "complaint to The Listener" , "Pain in an aural appendage" , "sort of pain" , "result of nagging?" .)
