Sens dessus dessous is a French set phrase that you can use when you want to say that something or someone is upside down, upset or in a great state of confusion.
It is commonly used both in a literal and figurative sense:
- Nous sommes rentrés dans la pièce : tout y était sens dessus dessous. (We entered the room: everything was in a big mess / everything had been turned upside down)
- C’était une catastrophe qui avait mis sa vie sens dessus dessous (It was a disaster that turned his life upside down)
Note that the final S in the word sens is usually always pronounced, but not in this very expression. It is clearly an exception… What is not a exception though is the fact that you should never pronounce the final S in dessus and in dessous 😉
There you are! Now you know what the French phrase sens dessus dessous means. Try and use it next time you have the opportunity to speak French! 🙂
