How to translate “By the way”? — Comment traduire « By the way » ?

Question

I want to translate a sentence that says something like “By the way, did you remember to get…?”So far I've seen two options: _au fait_ and _à propos_. Which one would be more appropriate for an informal talk?---J'aimerais traduire une phrase du type « By the way, did you remember to get…? », pour l'instant je vois deux possibilités, « au fait » et « à propos ». Laquelle est la plus adaptée dans le cadre d'une discussion informelle ?

Answer 1

Par ailleurs would be the best phrase for this because it suggests a tangential thought.

But au fait works very well here too because it changes the subject a bit.

A propos usually refers to something you've already said. (Literally means "upon the word," meaning the word(s) you spoke earlier.

So in a way it depends on what came before this.

Answer 2

Dans le cadre d'une discussion informelle, "au fait" me semble un très bon choix !
