Bonjour Aurélie et Cécile,
My problem is with this phrase in the above writing lesson
"...jacket that I bought FROM you two weeks ago." Correct translation given is :"que je vous ai achetée il y a deux semaines."
I can't find the lesson describing this usage of object pronouns. Why is it not "que j'ai acheté DE vous"? Does not "que je vous ai acheté" mean that I bought FOR you? Please explain using FROM in this context. Thanks!
