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