Might describe scream on getting hole in one (8)
I believe the answer is:
piercing
'one' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'might describe scream on getting hole in' is the wordplay.
I cannot really see how this works, but
'in' is within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for piercing that I've seen before include "Making a hole in (something)" , "Very cold (wind)" , "very loud" , "sharp" , "Shrill" .)
