Conjugate faire in Le Futur (future tense)

Well, even in English there's a slight difference between "are going to" and "will do their homework". In fact, the difference is very similar to the French future proche and future simple. The difference is that future proche is mostly used for things that the speaker considers not too far in the future. Futur simple is for more distant future actions.

Fiona, this is a subtle nuance only which, in some sentences, does make a difference.

For example: My stomach hurts,  I'm going to throw up. You wouldn't use "...I'll throw up" in this context, even though it's grammatically correct.

In many cases either is possible. But the distinction is more prevalent in French than it is in English.

Hi Arndís - no it's a bug. We're looking for a fix. For now, please add topics to your notebook and kwiz against that if you want to control which topics you kwiz against, or continue to do level kwizzes or your dashboard studylist recommendations.

Sorry about this.

I think they both describe the same situation, but there is a difference in register - the first sentence is more formal.

In the second sentence it sounds to me like the girls have decided to do their homework after lunch; in the first sentence it sounds like they've been told to, or they always do it then.

Hi Arndís,

I agree with Alan in that there is slight difference in register between, e.g.:

Je vais te dire. -- I am going to tell you.
Je te dirai. -- I'll tell you.

In addition, it seems that there is also slight different in temporal proximity. La future proche (Je vais te dire) is slightly closer to the present than la future simple (Je te dirai).
