Injury, damage (10)
I believe the answer is:
impairment
This clue is a double definition.
'injury' is the first definition.
(I've seen this before)
'damage' is the second definition.
(I know that damage can be written as impairment)
(Other definitions for impairment that I've seen before include "Disability" , "Injury" , "Weakening, damage" .)
