Editor unexpectedly ran amok (6)
I believe the answer is:
rioted
'ran amok' is the definition.
The answer and definition can be both to do with social activities as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'editor unexpectedly' is the wordplay.
'unexpectedly' indicates anagramming the letters.
'editor' with letters rearranged gives 'RIOTED'.
Can you help me to learn more?
(Other definitions for rioted that I've seen before include "Brawled" , "Of mob, ran wildly through the streets" , "Revolted" , "Ran amok like editor" , "Took part in violent civil disorder" .)
