French language Q&A Forum

Depuis has gotten confusing in this forum likely due to one comment stating emphatically that Depuis is used for a duration that starts and ends in the past. The lesson says no such thing, yet the incorrect comments show no clarification, and we are left to wonder. If Depuis cannot be used for a duration that starts and ends in the past, then something should be mentioned in the lesson, or, better, corrections should be added in response to the incorrect forum comments. Otherwise, it is confusing. Thank you much.

Also, when I was in school, we were told to use "au-dehors de" but you do not include it in the prepositions lesson. Do people use this preposition? It is in the Collins dictionary.

assister + à = to attend

Tu es means “you are”

So when you ask someone Are you hungry?

It should be 

Tu es faim?

But why are we saying?

Tu as faim?

From the fourth to the seventh. Why is it de quatre au sept and not du quatre? From the explanation it seemed clearly to be du in the lesson. What did I get wrong in this particular case? Thanks. 

Since the active voice was imperfect (Marie caressait son chat), why is not the passive voice also imperfect? I had chosen Son chat était caressé par Marie-

he will say that he play football
he will say that he played football

what are the rules for indirect speech when the main clause is future?

What is

Nous nous appelons?

And when do we use this?
