Без кворума нельзя голосовать.

Because the preposition без (without) requires the genitive case.

So:

• кворум = nominative, dictionary form
• без кворума = without a quorum

This is a very common pattern in Russian:

• без сахара = without sugar
• без воды = without water
• без разрешения = without permission

So без кворума is simply the normal grammatical form after без.

Нельзя is an impersonal word that usually means something like:

• it is not allowed
• it is impossible
• one must not
• you can’t

In this sentence, it most naturally means:

• it is not allowed to vote without a quorum
• or voting without a quorum is not possible/valid

Russian нельзя often covers both prohibition and impossibility, and context tells you which shade is stronger.

For example:

• Здесь нельзя курить. = Smoking is not allowed here.
• Без ключа нельзя открыть дверь. = You can’t open the door without a key.

In Без кворума нельзя голосовать, both ideas are possible: either the rules forbid voting, or voting cannot legally/procedurally happen.

Because Russian often uses нельзя + infinitive to express a general rule, prohibition, or impossibility.

So:

• нельзя голосовать = it is not allowed to vote / one cannot vote

This construction is very common:

• Нельзя шуметь. = One must not make noise.
• Нельзя входить. = No प्रवेश / Do not enter / Entry is not allowed.
• Здесь нельзя парковаться. = You can’t park here.

There is no specific subject stated. It is a general statement.

Because the sentence is impersonal.

Russian very often leaves out the subject when talking about general rules or conditions. English often uses:

• you can’t
• one must not
• it is not allowed

Russian instead commonly says:

• нельзя + infinitive

So Без кворума нельзя голосовать does not mean that the subject was forgotten. It is a complete and natural sentence meaning something like:

• You can’t vote without a quorum
• It is not allowed to vote without a quorum

Голосовать is the imperfective verb, and it is the natural choice here because the sentence states a general rule.

• голосовать = to vote, to be voting, to engage in voting
• проголосовать = to cast a vote, to vote once/to completion

With нельзя + infinitive, Russian often uses the imperfective when speaking generally:

• Нельзя курить. = Smoking is not allowed.
• Нельзя перебивать. = You must not interrupt.

If you used проголосовать, it would sound more like a specific completed act:

• Без кворума нельзя проголосовать. = It is impossible/not allowed to cast the vote without a quorum.

That version is possible in some contexts, but голосовать is broader and more natural for a general rule about voting procedure.

Yes. That is a very good translation.

Russian uses a different structure from English, but the meaning matches well:

• Без кворума нельзя голосовать.
• Voting without a quorum is not allowed.

Other natural translations include:

• You can’t vote without a quorum.
• It is not permissible to vote without a quorum.
• No voting is allowed without a quorum.

Кворум is a masculine noun meaning quorum.

Its dictionary form is:

• кворум

It declines like a regular masculine noun:

• nominative: кворум
• genitive: кворума
• dative: кворуму
• accusative: кворум
• instrumental: кворумом
• prepositional: о кворуме

In your sentence, you see the genitive singular:

• без кворума

No, Russian word order is fairly flexible.

The neutral version is:

• Без кворума нельзя голосовать.

But you could also say:

• Голосовать без кворума нельзя.

This version puts more focus on голосовать or on the whole action of voting.

The meaning stays basically the same, but the emphasis shifts slightly.

A rough sense of the difference:

• Без кворума нельзя голосовать. = Without a quorum, voting is not allowed.
• Голосовать без кворума нельзя. = Voting without a quorum is not allowed.

Both are natural.

Because Russian has no articles.

English distinguishes:

• a quorum
• the quorum

Russian does not have words like a and the, so кворум can mean either, depending on context.

In this sentence, English usually says without a quorum, but Russian simply says:

• без кворума

The exact nuance comes from the situation, not from an article.

They are close, but not exactly the same in structure.

• без кворума = without a quorum
• если нет кворума = if there is no quorum

So:

• Без кворума нельзя голосовать. = Without a quorum, voting is not allowed.
• Если нет кворума, нельзя голосовать. = If there is no quorum, you can’t vote.

These are very similar in meaning. The first is more compact and formal; the second is more explicit.

Yes, it sounds fairly formal or procedural, because of the word кворум and the general rule-like structure.

You might hear it in contexts like:

• meetings
• committees
• corporate procedures
• parliamentary settings
• official regulations

The grammar itself is normal everyday Russian, but the vocabulary makes it sound administrative or institutional.

The stress is on the first syllable:

• квОрума

The base form is:

• квОрум

So:

• без квОрума

Knowing the stress matters, because Russian stress is unpredictable and must often be learned word by word.

Sometimes, but the meaning would shift a little.

• Без кворума нельзя голосовать. = Voting without a quorum is not allowed / cannot be done.
• Без кворума невозможно голосовать. = It is impossible to vote without a quorum.

Нельзя often suggests a rule, prohibition, or practical impossibility. Невозможно focuses more strongly on impossibility.

In legal or procedural language, нельзя is often the better choice because it can imply that the rules do not permit the action.
