French language Q&A Forum

Just wondered if we can say "Il faisait froid tout hier soir" to emphasize "all night long"(though it doesn't seems correct to me).

I don't understand why "depuis" is used here despite the fact that we use "depuis" for ongoing actions as stated in the lesson below.

Using the present tense (Le Présent) - and not the compound past (Le Passé Composé) - in sentences with "depuis" (since/for) in French (French Prepositions of Time)

Can infinitif passé be used with avant de under some circumstances?

Here's an example sentence from my French class:

Il n'ira pas jouer avec ses amis avant d'avoir fini ses devoirs.

The question was to correctly conjugate the verb finir in the bolded place; I'd written finir (infinitif présent) in the first place.

in the sentence le dernier mois ou' la vraiment le raisin arrive a la maturite.

it should be quand and not ou'

Can you say "elle m'a tendu le doigt" instead of "sa doigt" because you know it's her finger?  I thought when it's obvious to whom the body part belongs, the French prefer not to specify as in "J'ai mal à la tête."

In an A1 focus test  I wrote"ton père est DANS la prison" because a prison is a physical enclosure. It was marked as incorrect. could you please explain why? Thanks.
