Usage notes: Au cas où is one of those ubiquitous French expressions you need to learn "just in case." (See what I did there?) The normal way to use it is in front of a clause with a verb in the conditional.

Par exemple…

J’apporte un parapluie, au cas où il pleuvrait.   I’m bringing an umbrella in case it rains.
Au cas où tu dépenserais tout ton argent, je te donne ma carte de crédit.   In case you spend all of your money, I’m giving you my credit card.

Variation: juste au cas où

Synonyms

  • dans le cas où
  • des fois que
  • pour le cas où

Informally, au cas où is added to the end of a sentence as a sort of filler when the reason doesn’t need to be stated explicitly.

Par exemple…

J’apporte un parapluie, au cas où.   I’m bringing an umbrella, just in case.
Je te donne ma carte de crédit au cas où.   I’m giving you my credit card, just in case.

The Subjunctivisor!

Does au cas où require the subjunctive?

No, au cas où does not take the subjunctive:

Par exemple…

J’amènerai un pull au cas où il ferait froid.
I’ll bring a sweater in case it’s cold.

 Au cas où is always followed by the conditional (as is dans le cas où).
