A restful form of civil disobedience (3-2)
I believe the answer is:
sit-in
This could be a double definition.
'a restful form' is the first definition.
'sit in' can be an answer for 'form' (I have seen 'form of protest' mean 'sit in' so perhaps 'form' could also mean 'sit in'). I am unsure of the 'a restful' bit.
'civil disobedience' is the second definition.
(I know that sit-in is a type of civil disobedience)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for sit-in that I've seen before include "Protest occupying building" , "Type of demo" , "Occupation of building as form of protest" , "Form of civil disobedience" , "Occupation demo" .)
