Comments on targets (7)
I believe the answer is:
remarks
'comments' is the definition.
('remark' can be a synonym of 'comment')
'on targets' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'targets' becomes 'marks' ('mark' can be a synonym of 'target').
're'+'marks'='REMARKS'
(Other definitions for remarks that I've seen before include "Comments, observations" , "See 14" .)
