Hide the real wound (7)
I believe the answer is:
leather
'hide' is the definition.
(an animal hide)
'the real wound' is the wordplay.
'wound' indicates anagramming the letters (wound can mean twisted or turned around).
'the'+'real'='thereal'
'thereal' with letters rearranged gives 'LEATHER'.
(Other definitions for leather that I've seen before include "kid, say" , "Dressed hide" , "Treated hide" , "A tanner produces it from hide" , "Flog; hide" .)
