Returned with record business to be dealt with (7)
I believe the answer is:
backlog
'business to be dealt with' is the definition.
I can't tell whether this defines the answer.
'returned with record' is the wordplay.
'returned' becomes 'back' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'record' becomes 'log' (log is a kind of record).
'back'+'log'='BACKLOG'
Can you help me to learn more?
(Other definitions for backlog that I've seen before include "Work outstanding" , "Accumulation of uncompleted business" , "Quantity of work still to be done" , "work piling up" , "Accumulation of uncompleted work" .)
