French satire, not entirely truthful (6)
I believe the answer is:
candid
'truthful' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for candid that I've seen before include "Frank, honest" , "Open and truthful" , "Impartial" , "Frank - open" , "Frank and outspoken" .)
