Both of these words mean "since" in English but I am unsure of the rules governing which one to use when. Can someone help please?

  • puisque is actually a causality/comparative/ because.... depuis means after/ since. depuis does not imply causality. Jun 29, 2020 at 15:12

1 Answer 1


Puisque has a cause/effect meaning and it is used when since is a synonym of because:

Since you are in the kitchen, could you bring me a cup of coffee?
Puisque tu es dans la cuisine, pourrais-tu m'apporter une tasse de café ?

Depuis is for the cases where since have a meaning of time, space or when we are speaking about series:


This company is serving customers since 1892.
Cette société est au service des ses clients depuis 1892.


You have been bothering me since Paris!
Tu m'ennuies depuis Paris !


They are all there, from the first to the last.
Ils sont tous là, depuis le premier jusqu'au dernier.

Mind that this one could also, in a less formal way translate to

Ils sont tous là, du premier au dernier.

  • That second example is time, isn't it - more or less the same as depuis le moment qu'on a quitté Paris, but a bit less emphatic. I think space would have to be depuis + lieu, e.g correspondances depuis la gare du nord, trajet depuis Hanoi ...

  • Paris is a location not a time. Although, yes, that might imply that "and so it is a long time" so it is the same as your example. See point 2 there: dictionnaire-academie.fr/article/A9D1606 Jun 28, 2020 at 11:02

    Yes Paris is a location, but your example doesn't say depuis Paris, it it says depuis qu'on a quitté Paris, which is a reference to a point in time. I think your translation into English is correct, and the English obviously refers to a time.
