Literally, "good word" (3,3)

I believe the answer is:

bon mot

(Other definitions for bon mot that I've seen before include "Appropriate word or expression - in France" , "Witty words" , "Witticism" , "The right or apposite word - in France" , "quip" .)

I've seen this clue in The New York Times.
