Instrumental case in the passive

There can be two constructions in Russian
- active (the subject does the action and is actively directed to the object),
- passive (an action is performed on the subject)
Instrumental case in the passive
Компа́ния организу́ет конфере́нцию. ← активная конструкция

Nominative case
Accusative case

Subject is in the Nominative case. The action is actively performed by the subject.

Конфере́нция организу́ется компа́нией. ← пассивная конструкция

Nominative case
that ends in -СЯ
Instrumental case

The action is performed on the subject, so the subject is in the Instrumental case. The transitive verb is replaced by the same verb with the postfix -СЯ. Object in the Nominative Case.

Often in passive constructions there is no subject → Пи́сьма отправля́ются по по́чте. (we do not know who sends letters)

Important! Only transitive verbs (used with a noun that designates a direct object, "patient") can be changed from an active to passive.

Conclusion: When you want to replace an active with a passive, you have to replace the transitive verb  by the verb with the postfix -СЯ. In passive constructions, the subject is used in the Instrumental case, and the object in the Nominative case.

Usage of Genitive case (singular) - part 1

The case system in Russian is a complex grammatical theme. But if you  understand the system and able to use it correctly, the Russian language will seem to become easy and very attractive.  ;) In total there are six cases in Russian:  Nominative (1), Genitive (2), Dative (3), Accusative (4), Instrumental (5), Prepositional (6).   And  in this post we will acquaint you with one of  the most frequently used - the Genitive case (2).

тащить - таскать

The verbs of motion   "тащить - таскать" refer to the movement of a heavy object, or an object that is difficult to move for some other reason. What other use cases are there in Russian?

ОН, ОНА, ОНО and ОНИ, or Categories "gender" and "plurality" of the nouns

It is very interesting to learn Russian. Do you agree? In Russian, all grammar is very systematized. The very first (and most important!) that you learn on the lessons of the Russian from grammar is gender (ОН, ОНА, ОНО) and plurality (ОНИ).
