Fail to stand out in civil disobedience (3-2)
I believe the answer is:
sit-in
'civil disobedience' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'fail to stand out in' is the wordplay.
I cannot quite understand how this works, but
'in' is present in the answer.
The remaining letters 'sit' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sit-in that I've seen before include "Seated protest" , "Passive occupation of a premises" , "Form of civil disobedience" , "Factory protest" , "Occupation demo" .)
