French language Q&A Forum

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 ?

Qu'est-ce-que cette citation veut dire ? 

"he must be worried sick at the idea that I'm worried/anxious about his silence" ?

Quoi ? S'il a mal, avec intoxication d'alimentation, cloué au lit, il a plus des problèmes que si elle est inquiété, non ?

Si ça n'est pas correct, je n'en aucune idée. 

The phrase in English was "I will introduce her to Amelie" (sorry I don't have accents).  The translation given is je lui presenterai Amelie which I take to mean "I will introduce Amelie to her".  Should it not be "je la presenterai a Amelie"?

In the example, “Achète-t-il des pâtes?”:

“achète” technically ends in a vowel but it ends in a T sound, right? So why is the extra “t” necessary?

Please help me how to use 'la voilà' le, les voilà etc. Is it an expression or something else? Thank you. 

There seems to be a mistake on this page. Everything is in English!

the est-ce que sounds really wrong and nasally

Beyond the challenging dictée : What a beautiful, inspiring write-up. Falling deeper in love with French culture. Can't wait to google Coluche after supper. Merci!

Because "gens" is "people" - plural - I put "...les gens qui sortent constamment leurs portables de leurs poches". Is there anything in the pronuncation that I missed that showed it was definitely singular? Or is it a rule in french that you would always say "they took their phone from their pocket" unless they all owned several phones and were taking them out of more than one pocket each? Or...was my answer plausibly a correct hearing?

Could the postman say “je fais un boulot important”?
