Usage notes: The French expression tout d’un coup is used with two somewhat similar meanings, but one of them is wrong.

The real meaning of tout d’un coup is “all at once, in a single move, in one fell swoop.”

Par exemple…

Le sĂ©isme a dĂ©truit le village tout d’un coup.   The earthquake destroyed the town in one fell swoop.
Tout d’un coup, il a saisi ses affaires et est parti.   All at once, he grabbed his things and left.

Variation: d’un coup


  • d’un seul coup
  • d’un trait (with a verb like boire or avaler)
  • en une seule fois
  • en une seule gorgĂ©e (boire, avaler)

 Tout d’un coup is an indicator that you need the passĂ© composĂ© rather than imparfait.

 Faux synonym

Native French speakers commonly – but mistakenly – use tout d’un coup to mean tout Ă  coup.

Tout d’un coup, la voiture s’est retournĂ©e.   All of a sudden, the car flipped over.
Really means: In a single move, the car flipped over.
Je lisais quand tout d’un coup j’ai eu une idĂ©e.   I was reading when I suddenly had an idea.
Really means: I was reading when I had an idea all at once.
