Continued putting the lot in a rush (7)
I believe the answer is:
resumed
'continued' is the definition.
(resuming is a kind of continuing)
'the lot in a rush' is the wordplay.
'the lot' becomes 'sum' (I can't justify this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
'a rush' becomes 'reed' (plants found by water).
'sum' inserted within 'reed' is 'RESUMED'.
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for resumed that I've seen before include "Began again" , "Once again picked up" , "Restarted" , "got to work on again" , "Started again after a break" .)
