Stolen cabinet is damaged, for sure (13)
I believe the answer is:
incontestable
'sure' is the definition.
(I've seen this before)
'stolen cabinet is damaged' is the wordplay.
'is damaged' indicates an anagram.
'stolen'+'cabinet'='stolencabinet'
'stolencabinet' with letters rearranged gives 'INCONTESTABLE'.
'for' acts as a link.
(Other definitions for incontestable that I've seen before include "sure" , "Beyond dispute" , "Without doubt" .)
