Editing subversive Lit (7)
I believe the answer is:
ignited
'lit' is the definition.
(synonyms)
'editing subversive' is the wordplay.
'editing' can be anagrammed to 'IGNITED'.
Though, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for ignited that I've seen before include "Set alight" , "Caught fire" , "Gin diet (anag.)" , "Sparked off" , "Kindled" .)
