Writing the points to mention (5)
I believe the answer is:
essay
'writing' is the definition.
(essay is a kind of writing)
'points to mention' is the wordplay.
'points' becomes 'es' (E is an example).
'to mention' becomes 'say' (I've seen this in another clue).
'es'+'say'='ESSAY'
'the' acts as a link.
(Other definitions for essay that I've seen before include "School compeosition" , "Written academic work" , "Attempt; written piece" , "Trial, piece of writing" , "Make an effort or attempt" .)
