Remark on how Gallic it is (7)
I believe the answer is:
comment
This clue could be a double definition.
'remark' is the first definition.
(commenting is a kind of remarking)
'how gallic it is' is the second definition.
I know that 'how' relates to this answer.
'on' is the link.
Can you help me to learn more?
(Other definitions for comment that I've seen before include "Nancy's version of how" , "Explanatory note" , "How suitable for Le Monde" , "Leader writer's forte" , "observation" .)
