French language Q&A Forum

This lesson has me scratching my head with the simple question - why is it here? One of the very few things I remember from O level french (failed) was that regular past participles form ER>é, IR>i and RE>u so to my way of thinking battre follows the regular rule. Maybe this is because french is taught differently in France than it was in England 40 years ago, I remember reading somewhere that the french don't have the same concept of group 3 (-RE) verbs but have several smaller groups including -DRE.

sur la façade duquel on peut lire...

on dit 'duquel', même si 'façade' est un mot feminine ? 

Or 

"Oh Je l'ai regardé aussi hier"

I got the sentence “Nous n’avons pas eu....” wrong because I translated it as “We never had...”

In "Je vais à Paris" the s in vais is not pronnounced, but I had also undestood that when the word ends in a consonant, and the next word is a vocal, you pronounce the last letter to kinda carry the "flow", I forgot what the proper name for the rule was.

I’m having real difficulty pronouncing this sentence  and I’m wondering whether in conversation the « ne » is dropped to ease pronunciation.
