Servant goes with crowd for violent disorder (7)
I believe the answer is:
rampage
'violent disorder' is the definition.
(synonyms)
'servant goes with crowd' is the wordplay.
'servant goes' becomes 'page' (I can't justify this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'crowd' becomes 'ram' (I've seen this before).
'page' after 'ram' is 'RAMPAGE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for rampage that I've seen before include "Run riot" , "Violent disorder" , "Violent action" , "Destructive spree" , "Rioting, for example" .)
