Does it make a little hole in the green? (3)
I believe the answer is:
pin
'green?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'does it make a little hole in' is the wordplay.
I cannot quite understand how this works, but
'in' is present in the answer.
A single letter 'p' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for pin that I've seen before include "Skittle; fix" , "Small brooch; skittle" , "Small object to fasten or attach" , "Secure" , "Fastener; skittle" .)
