Force Yank to censor wife's language (6)

I believe the answer is:
french
'language' is the definition.
(French is an example)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for french that I've seen before include "Shellac dissolved in alcohol, used on furniture" , "From Paris possibly" , "European language" , "-- Polish; -- stick" , "eg Marie Antoinette" .)
