Remark, observation (7)
I believe the answer is:
This clue is a double definition.
'remark' is the first definition.
'observation' is the second definition.
(I've seen this in other clues)
(Other definitions for comment that I've seen before include "observation" , "offer opinion" , "Nancy's version of how" , "Remark, observe" , "How suitable for Le Monde" .)
