The sentence is " Où devrons-nous nous retrouver "

Why is nous repeated twice ? Even in the answer Marrie says

" Retrouvons-nous ici ... "
What does Retrouvons-nous mean ? And is it like a fixed expression or something ?


Also What does " Pourquoi pas " in " Pourquoi pas à 6 h.30 " mean ?
Doesn't it mean " Why not " ? if it does then why is the english translation of the lesson is " How about 6.30 ? "

The first "nous" is the pronoun (=we) and the second is part of the verb "se retrouver" (= to meet up in your sentence):
Tu me retrouves...
Je te retrouve...
Tu le retrouves...
Tu nous retrouves...
Nous nous retrouvons...
etc...

"Pourquoi pas" means "why not" or in this case "how about". English is not a simple translation of French and vice versa, so sometimes you can't translate literally.

Oh yes ! I have looked it up . Verbs that have Se+Verb in infinitive are called Pronomial Verbs .
Thank you so much ! that was so helpful ! I'll study them now .

And yeah I understand that xD Thanks :)
