Broken, ruined (5)
I believe the answer is:
kaput
I believe this clue is a double definition.
'broken' is the first definition.
(I've seen this before)
'ruined' is the second definition.
(I've seen this before)
(Other definitions for kaput that I've seen before include "Slangily broken, from German" , "Completely broken down" , "Out of order,or broken, from German" , "not 10 [IN ORDER]" , "Ruined (slang)" .)
