Rebel fed up with revolutionary, etc (6)
I believe the answer is:
defect
'rebel' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'fed up with revolutionary etc' is the wordplay.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'with' says to put letters next to each other.
'revolutionary' is an anagram indicator.
'fed' backwards is 'def'.
'etc' is an anagram of 'ect'.
'def'+'ect'='DEFECT'
Can you help me to learn more?
(Other definitions for defect that I've seen before include "go over to the other side" , "Desert - blemish" , "Fault, flaw" , "Blemish, fault" , "Abandon one's country in favour of an opposing one" .)
