The Russians also use the preposition к to mean “to” in the sense of “to someone's home/place.” К becomes ко before certain words, most particularly in the phrase «ко мне».

That last sentence, of course, is rude. It has about the same emotional punch as “Go to hell” does in English.

The Russians also use the preposition у to mean “at” in the sense of “at someone's home/place.” In this sense it is similar to chez in French.

Actually the meaning of у is a bit broader. It can also mean a person's office or workplace:

Let's think about the verb делать/сделать. The nice thing about this verb is that it is completely regular: it has no irregular endings whatsoever.

The first meaning of the verb is “to do.” It can bear this meaning in any tense:

Actually, the question in the past tense can be said either in the perfective or the imperfective, although they don't mean quite the same thing. Remember that the perfective is used when the focus of the question is on the result of an action, and the imperfective is used if result is not particulary in focus. So, for instance, let's say you walk into a room and see your beloved for the first time in two days and you want to know what s/he did the day before. That context does not focus particularly on result, so you use the imperfective verb and ask «Что ты вчера делал(а)?» “What did you do yesterday?” In response you will hear some vapid comment about window shopping and visiting relatives. But if, for instance, you walk into a room bespattered with blood and there is a corpse lying on the floor with a grimace on its face and a knife protruding from its chest, then the result of your beloved's actions are in the forethoughts of your mind and you use the perfective verb and say, «Что ты сделал(а)!?» “What have you done!?” If you deduce from that contrast in translation that the English present perfect tense has something to do with a past action with current relevance, then you have made a linguistically astute observation.

Less dramatic situations work as well. At the end of a typical school day you may say to your son «Что ты сегодня делал в школе?» “What did you do at school today?” But if you walk into the kitchen and see that he has covered all the walls with mustard, then you say, «Что ты сделал?» “What have you done?”

The verb also means “to make.” The thing that is made appears in the accusative case, and the thing or substance of which it is made shows up in the genitive case after the preposition из:

The second-most common word for “to” in Russian is “на” followed by the accusative case. This is potentially confusing because “на” followed by the prepositional case often means “at.” Observe the contrast:

“На” followed by accusative can also be translated as “onto”:

The most common word for “to” in Russian is “в” followed by the accusative case. This is tricky for Gringos because “в” followed by prepositional means “at.” Observe the contrast:

“В” can also indicate motion and be translated as “into”:
