French language Q&A Forum

For this example:

Je ne comprends pas le temps que ça lui prend de se préparer !I don't understand the time she takes to get ready!
Isn't the subjunctive of prendre supposed to be prenne?

I'm confused by the correct answer to this question:

>>La population du Nigeria est de plus de ________ personnes.

I wrote "un cent million de". However, the correct answer was "cent millions de".

Why do we drop the "un" in this case (unlike the examples)? Why is "millions" plural, even though it is only 1 million?

When translating the name Maryse Lépine I just assumed it was the same in french as in english but it is corrected to l'Épine. Is that right?

In this lesson you teach both forms are correct but in the exercise you mark s'asseyent as incorrect. Why?

I've read all the comments here and in the related links, several times.

It seems the rule be stated as, there's NO gender/number agreement of the participle when there is a direct object following the verb.

Ça vous dit ?

I came across this question in the quizzes. Why are these two sentences correct? One uses the feminine form and the other the masc. They are both referencing the time in the past. How does one determine if it is about the duration or precise moment?

“J’ai passé la journée avec Martin.”

I spent a day with Martin

“J’ai passé un an en Espagne quand j’avais dix-neuf ans.”

I spent a year in Spain when I was 19

Sometimes Vouloir (to want) is conjugated as veux at the present tense, but sometimes it is conjugated as veux for the pronoun je. Does this have to do with formality?

In the other lessons, i saw that "De qui" "Qui" "Dont" "Lequel" and "Duquel" are having the same literal meanings in the English translation. Can, you explain this briefly?

Eg.  Le garçon à côté de qui tu es assise a de beaux yeux.

Eg. Voici les amis au sujet desquels nous sommes inquiets. 

Eg. Le garçon dont tu parles est très gentil.

Eg. La fille derrière qui je suis assis est belle. 

All of them means "Whom' may i know why? and all of them seem so complicated while they literally mean the same. 

What do the letters OVNI stand for ?
