Complete confusion of business meeting swamped by papers (8)
I believe the answer is:
quagmire
'complete confusion' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'business meeting swamped by papers' is the wordplay.
'business meeting' becomes 'agm' (abbreviation for annual general meeting).
'swamped by' means one lot of letters goes inside another.
'papers' becomes 'quire' (I've seen this in other clues).
'agm' placed into 'quire' is 'QUAGMIRE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for quagmire that I've seen before include "problematic situation" , "Boggy ground" , "Swamp" , "Swampy marsh" , "difficult situation" .)
