Horrific cut — may result in this (4)
I believe the answer is:
scar
'result in this' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'horrific cut' is the wordplay.
'horrific' becomes 'scary' (I've seen this in another clue).
'cut' means to remove the last letter.
'scary' with its last letter taken off is 'SCAR'.
'may' is the link.
Can you help me to learn more?
(Other definitions for scar that I've seen before include "Injury mark - cliff" , "Fish" , "Sign of wound" , "Disfigure" , "Long (for)" .)
