Make a score (5)
I believe the answer is:
notch
This might be a double definition.
'make' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'a score' is the second definition.
(I know that score has the is a more specific form of the action notch)
Can you help me to learn more?
(Other definitions for notch that I've seen before include "Snick" , "Gouge" , "small score?" , "Mark indented in wood etc" , "Cleft" .)
