Hello, I have a doubt I wish to clear out. As i have a couple of doubts on each preposition expressing "from" in russian I am going to list how would be each preposition used and a small sentence. I would love to hear from you any correction about the sentences and on the proper usage of each preposition. у + Genitive I believe this is used when referring to taking something from someone, but I don't know when the motion thing kicks in exactly. For example ты у меня весь итальянский язык будешь усвоить. от + genitive I suppose its used when motion kicks in, But at times I don't happen to understand what is difference with с. я брал ручку от(у)? твоего чемодана . On the otherhand I don't understand if there is any motion involved. Does "motion" strictly refer to walking,flying, etc. etc.? Although so I'd wonder, why is this sentence supposed to be right? Я получила это письмо от кого-то. Where is the motion involved into this? с + genitive It would be meant to be used for origins, such as с какой народа - вы? Please only detailed explanations. Thank you in advance.
