French language Q&A Forum

I am renovating a house in France. I need to communicate with the workers building construction terms. I would like some exercises with that content please.

I am struggling to work out what the "en" refers to. I presume it is "of something", but can't work out what (or where the "of" comes from) - the sentence seems to work equally well without it.

Statement: ...Je me sens beaucoup mieux !  Question: Tu sens une différence ?

Why does the question use sentir and not se sentir (ie, "Tu te sens...)?  Is it because the statement is about feeling better ("internal" feeling) and the question is about feeling a difference (perceiving something)?  Would "Tu te sens mieux ?" be a correct way to ask if someone is feeling better?

Would not "préparez un bol de bouillie be acceptable?

Quelle est la différence entre "d'abord," "au début," et "pour commencer ?" Il y a des nuances d'utilisation ? 

Is it not also valid to ask, “Ça te dire…?” In place of “Est-ce que tu veux..?”
