Is it sharper if pricked? (3)
I believe the answer is:
ear
'it sharper if pricked?' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ear that I've seen before include "Organ of hearing" , "organ with drum" , "Van Gogh missing body part" , "Lughole" , "Lend one and listen" .)
