The most common verb pair for “to close” in Russian is закрывать/закрыть:

The person who closes something goes in the nominative case, and the thing closed goes in the accusative:

This very common verb can be used to illustrate some of the amazing flexibility of Russian grammar. Let's say I was supposed to buy bread at the store, but I got there too late. I might explain the situation like this:

All three sentences are grammatically correct and communicate essentially the same idea, but they are syntactically very different. Sentence 1 is a passive sentence where магазин is the subject and закрыт is a short-form past passive participle. Word for word it could be represented as “Store already was closed.”

In sentence 2 магазин is in the accusative case as the direct object of the verb закрыли. The verb is in the plural past tense with an implied “they” as the subject. Word for word it can be represented as “Store already (they) had closed.” Sentences with an unexpressed “they” are very common in Russian, and they are called indefinite personal sentences. They are used when they actual doer of the sentence is not particularly important in the context in which the sentence is uttered.

In sentence 3 магазин is in the nominative case as the subject of the reflexive verb закрылся. We call this use of a reflexive verb the medio-passive meaning, where the subject of the verb undergoes a change of state but the people who cause the change are not significant to the context. Word for word the sentence can be represented as “Store already had closed.”

The medio-passive use of the reflexive is common in other verbs like октрываться-открыться, начинаться-начаться, заканчиваться-закончиться, and пролжаться-продолжиться. We will discuss the medio-passive use of закрываться/закрыться in the near future.
