Engraves points (6)
I believe the answer is:
scores
'engraves points' is the definition.
I can't tell whether this definition defines the answer.
'engraves points' is the wordplay.
'engraves' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'points' becomes 'cores' (core is a kind of point).
's'+'cores'='SCORES'
Can you help me to learn more?
(Other definitions for scores that I've seen before include "Musical compositions in written form" , "Marks; is successful" , "Obtains marks, say" , "Scratches" , "Gains game points" .)
