French language Q&A Forum

Is it incorrect to use "Est-ce quoi la Sorbonne?". It was marked incorrect on a quiz.  Is that because I can't invert c'est in this case?

  I’m wondering what pesant is grammatically in the sentence "Ces informations valent leur pesant d'or !" - a gerund? Or is pesant d’or a fixed expression?

I selected nationality with Capital letter, but it says I selected lower case

So, as the rule in this lesson states that in Negation we use Ne...Personne instead of N'importe qui for saying 'anyone' ...so, should it be? - 

- Elle ne fait personne confiance. [She does not trust anyone.] Because the negation surrounds the main conjugated verb?

The recommended translation for 'what a powerful voice that man had!' is 'quelle voix puissante avait cet homme !'. I don't actually see this usage of inversion covered in any grammar guides. Is it the norm to invert subject and verb in a sentence beginning with an exclamatory adjective?

In what part of this sentence could you add "nearly", and what is the word for this? If I said, "My parents have been married for 20 years", or "Mes parents sont mariés il y a vingt ans", how would I say "My parents have been married for nearly 20 years" ? Does this require a different expression entirely? For context, I would be explaining that their wedding anniversary is next month.

Why does pronom relatif eliminates a subject complement.

Eg:J'ai rencontré par hasard une amie;je ne l'avais pas vu depuis mon enfance.

In the exercise, how is "ils" a verb?

Not sure if anyone is gonna read this, but for those that are from countries where a billion means a million million, french uses the word billion as well. 

This page confused me a bit since Spanish is my first language and in that language we generally use billion the same way as French, whereas the one thousand million meaning is mostly used in the English speaking world.
