French language Q&A Forum

I have let my writing and dictation practice slip because I’m speaking French on a daily basis, but a lesson like this one brings home the need to keep at these weekend challenges, keep practicing, keep adding to the vocabulary bank, keep addressing the grammar. 

Qu'est-ce que le "en" remplace dans cette expression? "je n'en croyais pas mes yeux"

Pourquoi est la langue française si confusant?

In the question "Nous ________ les cheveux.” (We brushed our hair) (HINT: Conjugate "se brosser" (to brush) in the compound past (Passé Composé)), why is “nous sommes brossé” preferred over “nous sommes brossés”?

I think that “we” is plural, so the correct response should be “brossés” with the “s”.

There are clearly only two participants in this conversation, who are at least friends, if not relatives. 

Should it not be:  Attention de ne pas te brûler  ?

 Why does the verb 'détester' not require the ne explétif in this sentence:  Les filles détestent que vous les embêtiez. 

why is there a 'de' before 'partager' here? what is this for?

The end of the passage states, "d'ici trois jours ouvrables" or "dans", but the English phrase to translate is "within" so should en not be used instead of dans? En being within and dans being similar to after ex number of days. 

When do I use j'ai or je suis because they both mean the same thing so I don't know when's the time to use which I have

Is there a mistake in the video at approximately the 1:08 mark? The example says:

Je mange une pomme and Tu *parle* à Marie. Shouldn't it be Tu *parles* à Marie?
