The deep wound seared (3,3)
I believe the answer is:
red sea
'the deep' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'wound seared' is the wordplay.
'wound' is an anagram indicator (wound can mean twisted or turned around).
'seared' anagrammed gives 'RED SEA'.
Can you help me to learn more?
(Other definitions for red sea that I've seen before include "It leads north to the Suez Canal" , "It parted for Moses and the Israelite (3,3)" , "It divides Arabia/Africa" , "Colourful body of water between N Africa and Arabian peninsula" , "large volume of saline solution" .)
