Wrecked in rude fashion (6)
I believe the answer is:
ruined
'wrecked' is the definition.
(thesaurus)
'in rude fashion' is the wordplay.
'fashion' is an anagram indicator.
'in'+'rude'='inrude'
'inrude' with letters rearranged gives 'RUINED'.
(Other definitions for ruined that I've seen before include "Destroyed, undone" , "Bust" , "Irreparably damaged" , "Broke" , "Devastated" .)
