Broken in rude fashion (6)
I believe the answer is:
ruined
'broken' is the definition.
('ruin' can be a synonym of 'break')
'in rude fashion' is the wordplay.
'fashion' is an anagram indicator.
'in'+'rude'='inrude'
'inrude' is an anagram of 'RUINED'.
(Other definitions for ruined that I've seen before include "shot" , "Bankrupt" , "Destroyed or bankrupted" , "Utterly destroyed" , "Bankrup - destroyed" .)
