Carry out an illegal suspension (5)
I believe the answer is:
lynch
'carry' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Maybe you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lynch that I've seen before include "Hang illegally as by mob" , "Illegally put to death" , "Punish without trial" , "Hang (someone) illegally" , "- - law (= mob violence)" .)
