Bez kworum wspólnota mieszkaniowa nie może uchwalić planu.

Bez means without. It requires the genitive case.

So in bez kworum, the noun after bez must be in the genitive.

A few similar examples:

• bez cukru = without sugar
• bez problemu = without a problem
• bez dzieci = without children

Good question. Kworum is one of those nouns whose singular form stays the same across cases.

So:

• nominative: kworum
• genitive: kworum
• after bez: still kworum

That means the case is being shown by the grammar of the sentence, not by a visible ending change.

It is a fairly specific legal/administrative expression. It usually refers to a homeowners’ association, housing community, or the body of owners in a residential building who make joint decisions about the property.

Literally:

• wspólnota = community
• mieszkaniowa = housing/residential

So this is not just any community; it is a formal group connected with a residential property.

In Polish, adjectives often come before the noun, but in official terms, institutional names, and set legal expressions, the adjective often comes after the noun.

So wspólnota mieszkaniowa is a fixed term, not just a random descriptive phrase.

This post-noun position is common in formal language, especially in law, administration, and bureaucracy.

Because the grammatical subject is wspólnota, and that noun is singular.

Even though a wspólnota mieszkaniowa refers to a group of people, Polish makes the verb agree with the grammatical form of the noun, not with the number of people inside the group.

So:

• wspólnota ... może = the community can not
• wspólnota ... mogą

This is similar to English using singular with some collective nouns in certain contexts.

Because móc means can / be able to, and after it Polish normally uses an infinitive.

So:

• może uchwalić = can pass/adopt
• nie może uchwalić = cannot pass/adopt

This is very similar to English:

• can pass
• cannot pass

Here:

• może = can
• uchwalić = to pass/adopt formally

Uchwalić is a formal verb used for passing, adopting, or approving something by vote or official decision.

Typical things you can uchwalić:

• plan
• budżet = budget
• uchwałę = a resolution
• regulamin = regulations/rules

So this is not the everyday decide in a broad sense. It is more specifically formally adopt/pass something.

Because uchwalić is perfective, and uchwalać is imperfective.

• uchwalić focuses on the completed result: the plan gets passed
• uchwalać focuses more on the process, repetition, or ongoing action

In this sentence, the point is whether the community can successfully complete the act of adopting the plan. That is why uchwalić fits better.

No — bez affects kworum, not planu.

Planu is here because of negation.

In standard Polish, when a direct object is under negation, it often changes to the genitive:

• positive: może uchwalić plan
• negative: nie może uchwalić planu

So:

• bez kworum: genitive after the preposition bez
• planu: genitive because the clause is negative

Those are two different reasons.

The straightforward positive version would be:

Z kworum wspólnota mieszkaniowa może uchwalić plan.

or more naturally:

Jeśli jest kworum, wspólnota mieszkaniowa może uchwalić plan.

Notice the object:

• positive: plan
• negative: planu

That contrast is very useful to remember.

Polish does not have articles like English a/an and the.

So:

• plan can mean a plan or the plan
• wspólnota mieszkaniowa can mean a housing community or the housing community

The exact meaning comes from context, not from a separate word.

Yes. Polish word order is fairly flexible.

The original sentence:

Bez kworum wspólnota mieszkaniowa nie może uchwalić planu.

puts emphasis early on without a quorum.

Other possible orders include:

• Wspólnota mieszkaniowa bez kworum nie może uchwalić planu.
• Planu wspólnota mieszkaniowa bez kworum nie może uchwalić.
  This is more marked and would be used for emphasis.

The original order sounds natural, especially in formal or explanatory language, because it highlights the condition first.

Yes, definitely. It sounds formal, administrative, or legal.

That comes from words and phrases like:

• kworum
• wspólnota mieszkaniowa
• uchwalić plan

In everyday conversation, people might say something less formal depending on context, but this sentence is perfectly normal in official or semi-official Polish.
