Swamp company meeting, drowning in a lot of paperwork (8)
I believe the answer is:
quagmire
'swamp company' is the definition.
'quagmire' can be an answer for 'swamp' (I've seen this before). I am unsure of the 'company' bit.
'meeting drowning in a lot of paperwork' is the wordplay.
'meeting' becomes 'agm' (I've seen this in other clues).
'drowning in' means one lot of letters goes inside another.
'a lot of paperwork' becomes 'quire' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'agm' placed inside 'quire' is 'QUAGMIRE'.
Can you help me to learn more?
(Other definitions for quagmire that I've seen before include "Bog or marsh" , "Bog - impasse" , "You can get bogged down in this" , "Bog; complex situation" , "problematic situation" .)
