French language Q&A Forum

Hello,

I have a tiny question. If I want to say "I thought about her", should I use:

a) Je lui ai pensée

b) J'ai pensé à lui

c) J'ai pensé à elle

Because I notice that for verb + de, we can use "penser d'elle" (think of her), so for the case verb + à, can we use à + pronouns as well (option b,c)? Can we use "elle" instead of "lui" for such case? Finally, can we use option b) instead of a)?

Is it right that you don't pronounce the 'S' at the end of 'suis' when it's followed by 'à'?

I had thought anytime a vowel sound follows a word ending in 's', you pronounce that s. Like with 'Je dine dans une...'

I don't understand "nous a le plus marqués"  Maybe it should be "nous avons le plus marqués" ?

Why does "épaisse" go before the noun? Is "couche épaisse" incorrect?

Est-ce que je peux écrire

 baisser la température

a la place de 

faire descendre la temperature

Merci
