Грузовой отсек закрыт.

In Russian, the verb to be is normally omitted in the present tense.

So where English says:

• The cargo compartment is closed

Russian simply says:

• Грузовой отсек закрыт

If you wanted the past or future, Russian would use a form of быть:

• Грузовой отсек был закрыт = The cargo compartment was closed
• Грузовой отсек будет закрыт = The cargo compartment will be closed

So in the present tense, leaving out is is completely normal.

Грузовой is an adjective meaning something like cargo, freight, or for carrying cargo, depending on context.

It describes отсек:

• грузовой отсек = cargo compartment

Grammatically, грузовой is:

• masculine
• singular
• nominative

because it matches отсек, the noun it modifies.

Because the standard adjective formed from груз is грузовой.

This is just the normal dictionary form of that adjective. Russian does not always build adjectives in the most predictable way from a noun stem, so this is something you mainly learn as vocabulary.

Some common examples with грузовой are:

• грузовой отсек = cargo compartment
• грузовой лифт = freight elevator
• грузовой поезд = freight train
• грузовой автомобиль / грузовик = truck

So грузовой is simply the correct adjective here.

Отсек is in the nominative singular.

You can tell because it is the subject of the sentence: the thing being described as closed.

In Грузовой отсек закрыт:

• Грузовой отсек = the cargo compartment
• закрыт = closed

So the structure is basically:

• [subject] + [state]

The noun отсек is masculine singular, and the adjective грузовой agrees with it.

This is one of the most important grammar points in the sentence.

Закрыт is the short form.
Закрытый is the full form.

In Russian, the short form is often used predicatively — that is, when you say that something is in a certain state:

• Отсек закрыт = The compartment is closed

The full form is more often used before a noun as a normal adjective:

• закрытый отсек = a closed compartment

So:

• отсек закрыт = the compartment is closed
• закрытый отсек = a closed compartment

This is why закрыт is the natural choice here.

For a learner, the most useful way to think of закрыт here is: it functions like a short-form predicate adjective, though historically it comes from a participial form.

What matters in practice is this:

• it describes the state of the compartment
• it agrees with the noun in gender and number

Compare:

• отсек закрыт — masculine singular
• дверь закрыта — feminine singular
• окно закрыто — neuter singular
• двери закрыты — plural

So even if grammar books classify it in slightly different ways, for everyday use you should recognize it as the normal Russian way to say is closed.

Because отсек is masculine singular, and закрыт is also the masculine singular short form.

Here is the pattern:

• закрыт — masculine
• закрыта — feminine
• закрыто — neuter
• закрыты — plural

Since отсек is a masculine noun, Russian uses:

• отсек закрыт

If the noun were feminine, for example дверь, you would say:

• дверь закрыта

Yes. Russian word order is more flexible than English word order.

The neutral order here is:

• Грузовой отсек закрыт

But you could also say:

• Отсек закрыт
• Закрыт грузовой отсек

The meaning stays basically the same, but the focus changes.

• Грузовой отсек закрыт sounds neutral.
• Закрыт грузовой отсек can sound more emphatic or like an announcement.

In most basic contexts, the original order is the most straightforward.

No. Russian has no articles like English a/an and the.

So Грузовой отсек закрыт could be understood as:

• The cargo compartment is closed
• A cargo compartment is closed

In real usage, context usually makes it clear. In a situation like a spaceship, aircraft, or vehicle announcement, English would normally translate it as the cargo compartment is closed.

The stress is:

• грузово́й отсе́к закры́т

A rough pronunciation guide for an English speaker:

• groo-zuh-VOY
• ut-SYEK
• zuh-kriht

A few helpful notes:

• грузовой has stress on the final -ой
• отсек has stress on the second syllable
• закрыт has stress on the last syllable
• unstressed о is reduced in pronunciation, so it often sounds closer to uh than a clear English o

Usually yes, but the exact English word depends on context.

Отсек can mean:

• compartment
• section
• bay
• hold

So грузовой отсек might be translated as:

• cargo compartment
• cargo bay
• cargo hold

For example:

• in a spaceship or sci-fi setting, cargo bay may sound most natural
• in an aircraft or vehicle, cargo compartment may fit better

So the Russian is the same, but the best English translation can vary with context.

In many situations, yes, the Russian can imply the resulting state after an action.

So Грузовой отсек закрыт mainly means:

• The cargo compartment is closed

But depending on context, it may also suggest:

• The cargo compartment has been closed

Russian often focuses on the state itself rather than choosing between English-style is closed and has been closed. The exact English wording depends on what sounds most natural in context.
