  5. Au vs Pour?


Au vs Pour?

So I've been Googling for an answer, but all it comes up with is A vs De, which I don't think will help.

What is the difference between the two? Can they be used interchangeably? (For example, Duolingo marked me wrong for using pour before petit-dejeuner).

I'm a bit confused on the specifics of your question, but even so I can tell you that there aren't really any one-to-one relationships between English and French use of prepositions. And like in English, they can often seem arbitrary. This is the case with most languages. Short answer: You just have to memorize them.


Also, petit déjeuner is not hyphenated and is always preceded by the definite article le (as it is a masculine noun). This may go some way to explaining why au (à + le) is used and not pour.

ex Je te verra au petit déjeuner → "I'll see you at breakfast".

But, as aistobe has pointed out, prepositions do not align between French and English so need to be memorised.


What was the whole sentence where you were using a preposition with "petit dejeuner"? Context matters with prepositions. Maybe then we can explain it for you.
