Let out red mark left by wound (4)
I believe the answer is:
scar
This clue could be a double definition.
'let out red' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'mark left by wound' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for scar that I've seen before include "Healed-cut mark" , "Leave wound mark" , "Old wound - bare cliff" , "Evidence of an old wound" , "Mark on body or tree" .)
