French language Q&A Forum

In this example, "You are leaving next Tuesday, aren't you", the correct answer used the present tense to indicate immediate future, but next Tuesday is not the immediate future.  What is the cut-off?  A week? A month? It varies?

Here it says that En can’t be used for people but I have heard it in the following context: Tu as des enfants, oui j’en ai trois. In this case en is referring to people? 

Why did it change from "on" to "nous" in the last sentence?  Is it just more common with commands?

Why is there a le in the dependent clause that begins with bien que

Bonjour, 

Why is it "Envoie-la-vous" not "Envoie-vous-la?" Aren't me/te/nous/vous always placed before le/la/les? Merci. 

"Pronunciation Note: 

Does that mean that the final -s is always pronounced if the meaning is positive? Is that how French people distinguish between 1) J'ai plus du temps and 2) J'ai plus de temps (where 2 is really Je n'ai plus de temps with the ne omitted as it often is in conversation). How do native French listeners tell the difference?

C'était tout ce à quoi je m'intéressais.

Why à quoi? Why not auquel since it's s'intéresser à [qch] ?

Thank you!
