Pinch notes (4)
I believe the answer is:
edge
'pinch notes' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'pinch notes' is the wordplay.
'pinch' becomes 'ed' (I can't explain this - if you can you should give a lot more credence to this answer).
'notes' becomes 'ge'.
'ed'+'ge'='EDGE'
Can you help me to learn more?
(Other definitions for edge that I've seen before include "Golden ingot" , "Bind" , "Brink or border" , "Inch; border" , "Final line" .)
