Expressions et mots français employés en anglais/French words or expressions used in English

Over the years, the English language has borrowed a great number of French words and expressions. Some of this vocabulary has been so completely absorbed by English that you might not realize its origins (mayonnaise, touché...). Other words and expressions have retained their "Frenchness" (a certain je ne sais quoi ) which you tend to be much more aware of.
Here is a list of  common french words or expressions that you use in English:


C'est la vie: Same meaning and usage in English and in French


Cliché: expression, idea, or element of an artistic work which has been overused to the point of losing its original meaning or effect, rendering it a stereotype


Cul de sac: Dead-end street


Déjà vu: This is a grammatical structure in French, as in "Je l'ai déjà vu"=> I've already seen it. It can also disparage a style or technique that has already been done, as in "Son style est déjà vu" => His style is not original. 
In English, déjà vu refers to the scientific phenomenon of feeling like you have already seen or done something when you're sure that you haven't.

Fiancé(e): engaged person, betrothed

Je ne sais quoi: Used to indicate a "certain something," as in "I really like Ann. She has a certain je ne sais quoi that I find very appealing."


Joie de vivre: The quality in people who live life to the fullest


Laissez-faire: A policy of non-interference


Pot pourri: A scented mixture of dried flowers and spices; a miscellaneous group or collection


Raison d'être: Purpose, justification for existing 


Rendez-vous: In French, this refers to a date or an appointment (literally, it is the verb se rendre - to go - in the imperative); in English we can use it as a noun or a verb (let's rendez-vous at 8pm).


RSVP: This abbreviation stands for Répondez, s'il vous plaît, which means that "Please RSVP" is redundant.


Touché: Originally used in fencing, now equivalent to "you got me."
