Morass of papers about meeting (8)
I believe the answer is:
quagmire
'morass' is the definition.
(I know that morass can be written as quagmire)
'of papers about meeting' is the wordplay.
'of papers' becomes 'quire' (I am not sure about this - if you are sure you should believe this answer much more).
'about' is an insertion indicator.
'meeting' becomes 'agm' (I've seen this in other clues).
'quire' going around 'agm' is 'QUAGMIRE'.
Can you help me to learn more?
(Other definitions for quagmire that I've seen before include "problematic situation" , "Bog - impasse" , "Wet bog" , "Morass" , "Boggy ground" .)
