Clear advice to anyone tending a dirty knife-wound (5-3)
I believe the answer is:
clean-cut
'clear' is the definition.
(I know that clear can be written as clean-cut)
'advice to anyone tending a dirty knife-wound' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found within the answer.
'wound' could be 'cut' (cut is a kind of wound) and 'cut' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for clean-cut that I've seen before include "Sharply-outlined" , "Well groomed" , "With a neat, respectable appearance" , "Appearing neat and respectable (of a man)" , "Tidy and respectable" .)
