It has point and makes sin spin (3)
I believe the answer is:
pin
'it has point and' is the definition.
The definition suggests a singular noun which matches the answer.
'sin spin' is the wordplay.
'PIN' is hidden within the letters.
However, I am not sure how the hidden word is indicated.
'makes' is the link.
Can you help me to learn more?
(Other definitions for pin that I've seen before include "Flagged stick placed in golf hole" , "Skittle; chess attack" , "Peg or nail" , "Fixing device" , "Sewer's aid" .)
