French language Q&A Forum

the pronunciation tip at the end of this page says that -ais and -ai are pronounced the same. I found a comment by a duolingo mod linking to two pages that says otherwise:

On forvo it does indeed sound like there is a subtle difference between aimerai and aimerais. é vs è. I hear the difference best when listening to other -ais words on forvo such as vais, sais, etc. It is subtle, but can someone else confirm that there is indeed an actual difference that contradicts the tip on this page?

I think it is very discouraging and disappointing for those who click on the first reading or listening exercise of A1 level, and then they see this passage.

Ce n' est pas le saint esprit qui est parti mais LES DISCIPLES donc qu'ils partent. 

When speaking can you say "un euro virgule cinquante centimes" or is it always "un euro et cinquante centimes"?

Perhaps the lesson on "Writing decimal numbers in French" could be updated to cover this topic as well.
