Мы освободили ячейку для хранения и вывезли стеллаж.

Because the subject is мы = we.

In Russian past tense, verbs agree with the subject in gender/number, not person. So with мы, you use the plural past form:

• мы освободили = we freed / we cleared
• мы вывезли = we took out / removed

There is no separate past-tense form meaning we the way English has I did / we did / they did. Russian uses one plural past form for we/you plural/they, and the subject tells you who did it.

Because it is in the accusative case.

The noun ячейка is a feminine noun ending in -а. When it is the direct object of the verb, it usually changes to the accusative:

• nominative: ячейка
• accusative: ячейку

Here it is the thing that was freed/cleared:

• Мы освободили ячейку = We freed/cleared the storage unit/compartment

So the -а → -у change is a normal feminine accusative pattern.

Literally, ячейка can mean cell, slot, compartment, or unit, depending on context.

In this sentence, because of для хранения (for storage), it most likely means something like:

• storage compartment
• storage unit
• locker
• storage cell

A very literal translation, cell, is possible, but in natural English you would usually pick a more context-specific word.

Russian often expresses this idea with noun + для + verbal noun / noun:

• ячейка для хранения = a compartment for storage

This structure is very common and natural in Russian. It is similar to:

• комната для отдыха = room for rest
• контейнер для мусора = container for trash
• место для парковки = place for parking

So instead of packing everything into one adjective, Russian often uses для to show purpose.

Хранения is in the genitive case.

That is because the preposition для normally requires the genitive:

• для хранения = for storage
• для работы = for work
• для детей = for children

The dictionary form is хранение (storage, keeping), and after для it becomes хранения.

No, хранение is a noun, not a finite verb.

It comes from the verb хранить = to store / to keep, but here it functions as a noun meaning:

• storage
• keeping

So:

• для хранения literally means for storage
• not to store

English often uses -ing forms in similar places, but in Russian this is a noun construction.

Because стеллаж is a masculine inanimate noun, and in the singular its accusative form is the same as the nominative.

So:

• nominative: стеллаж
• accusative: стеллаж

Since it is the direct object of вывезли, it is in the accusative, but you do not see a different ending.

This is very common with masculine inanimate nouns in Russian.

Вывезли comes from вывезти, which means something like:

• to take out
• to carry out
• to transport away
• to remove by taking it out

The prefix вы- often adds the idea of outward movement or out of a place.

So вывезли стеллаж suggests that the shelving unit/rack was not just moved somewhere inside the room, but taken out or removed from the location.

These verbs have different nuances:

• вывезли = took/transported out, often suggesting a larger object, vehicle, cart, or organized removal
• вынесли = carried out
• убрали = removed / put away / cleaned up

So вывезли стеллаж makes sense if the shelf unit was bulky and was physically taken away from the site, perhaps as part of storage, maintenance, or logistics work.

Both освободили and вывезли are perfective, which means the sentence presents the actions as completed results.

• освободили = cleared/freed completely
• вывезли = removed/took out completely

This fits the meaning well: the work was finished.

If you used imperfective forms, the sentence would sound more like describing an ongoing process, repeated action, or background activity.

Yes. The conjunction и means and, so the sentence gives two coordinated actions done by the same subject:

1. Мы освободили ячейку для хранения
2. (Мы) вывезли стеллаж

Russian often omits the subject in the second part when it is the same as in the first part. So мы is understood with both verbs.

Usually yes, at least in the way the sentence is presented.

The most natural reading is:

1. We cleared the storage compartment/unit
2. and removed the shelving unit

Russian often lists completed actions in the order they happened, especially with perfective verbs. So this sounds like a practical sequence of events.

Yes, Russian word order is flexible.

The original order is neutral and straightforward:

• Мы освободили ячейку для хранения и вывезли стеллаж.

You could rearrange parts for emphasis, but that would slightly change the focus. For example:

• Стеллаж мы вывезли, и ячейку для хранения освободили.

That sounds more marked or contrastive. For a normal factual statement, the original version is the best choice.

Стеллаж usually means a shelving unit, rack, or set of shelves.

It is not just one shelf. A single shelf would normally be полка.

So:

• полка = shelf
• стеллаж = shelving unit / rack

That is why вывезли стеллаж suggests removing a fairly substantial object.

Yes, especially in a practical, administrative, warehouse, office, or maintenance context.

It sounds like a factual report of completed work:

• a compartment/storage unit was cleared
• a shelving unit was taken away

So it is natural Russian, though a little more functional than conversational.
