Sharp knife wound admitted to AE (5)
I believe the answer is:
acute
'sharp' is the definition.
(I know that sharp can be written as acute)
'wound admitted to ae' is the wordplay.
'wound' becomes 'cut' (cut is a kind of wound).
'admitted to' indicates putting letters inside.
'cut' inserted into 'ae' is 'ACUTE'.
'knife' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for acute that I've seen before include "Excruciating" , "Severe; French accent" , "Grave" , "Piercing" , "Incisive" .)
