Resumptions of activities (6-2)
I believe the answer is:
goings-on
'resumptions of activities' is the definition.
The definition suggests a plural noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for goings-on that I've seen before include "Suspicious happenings" , "Suspect events or behaviour" , "Hanky-panky" , "Activities, esp. dubious ones" , "Funny business" .)
