Singing group many papers reported (5)
I believe the answer is:
choir
'singing group' is the definition.
(I've seen this before)
'papers reported' is the wordplay.
'papers' becomes 'quire' (I've seen this in other clues).
'reported' indicates a 'sounds like' (homophone) clue.
'quire' sounds like 'CHOIR'.
'many' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for choir that I've seen before include "Organised group of singers" , "Group of singers, often in church" , "Vocal group" , "People in church" , "Vocalists in group" .)
