Originality of points, three of them in all (7)
I believe the answer is:
newness
'originality' is the definition.
(I've seen this before)
'points three of them in all' is the wordplay.
I cannot really understand how this works, but
'points' could be 'nes' (NE is an example) and 'nes' is present in the answer.
The remaining letters 'news' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for newness that I've seen before include "Novelty" , "Fresh quality" , "originality" , "Freshness" .)
