Rumpus by drunk around society in tasks that need to be addressed (2-2,4)
I believe the answer is:
to-do list
'in tasks that need to be addressed' is the definition.
The definition suggests a singular noun which matches the answer.
'rumpus by drunk around society' is the wordplay.
I cannot really understand how this works, but
'around' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
'society' could be 's' (common abbreviation in names of organisations) and 's' is found in the answer.
'drunk' could be 'lit' (I've seen this in other clues) and 'lit' is located in the remaining letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for to-do list that I've seen is " Activity inventory".)
