Wound mark (4)
I believe the answer is:
scar
'wound mark' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scar that I've seen before include "Indication of damage" , "Blemish - cicatrix" , "sign of damage" , "Trace of an old injury" , "Healed-cut mark" .)
