Observations concerning points (7)
I believe the answer is:
remarks
'observations' is the definition.
(remark is a kind of observation)
'concerning points' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'points' becomes 'marks' (I've seen this before).
're'+'marks'='REMARKS'
(Other definitions for remarks that I've seen before include "Comments, observations" , "See 14" .)
