Example
1Person A: At first I did not like Alex he seemed a
bit unsympathetic, well not unsympatheic but not that talkative and a
bit reserved, you know what I
mean.
Person B: You
mean introverted
Person A: precisely le mot juste
Example 2 (From Frasier Season 5 Episode 8)
Frasier: Wait! Wait, my God, it's really for the sake of our future
relationships. I
mean, it just, I know that you're afraid to
hurt my feelings but I can stand a little constructive
criticism. Now, come on, please, what do you think are my
main faults?
Daphne: Well, if I had to choose, I'd say you are a bit of a fuss
budget.
Frasier: Fuss budget! Well, listen, if you
don't mind the
substitution, I think maybe "demanding" is more the mot
juste.
