C-section souvenir (4)
I believe the answer is:
scar
'c-section souvenir' 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 "Sign of wound" , "Indication of damage" , "Nasty mark" , "sign of damage" , "showing effect of damage to body" .)
