A ata da assembleia mostra que há quórum.

Here ata means the official written minutes or record of a meeting.

So A ata da assembleia = the minutes of the assembly/meeting.

It is not the same as English act in this context. A very common translation is:

• ata = minutes
• lavrar a ata = to draw up / write the minutes

One thing that can feel strange to English speakers is that minutes is plural in English, but ata is singular in Portuguese.

Yes. Ata is a feminine noun, so it normally takes feminine articles and adjectives:

• a ata
• esta ata
• a ata foi aprovada

So in the sentence, A ata da assembleia is grammatically feminine singular.

Because Portuguese usually contracts the preposition de with the definite article a:

• de + a = da

So:

• a ata da assembleia = the minutes of the assembly
• literally: the minutes of the assembly

This kind of contraction is very common in Portuguese:

• de + o = do
• em + a = na
• em + o = no

Assembleia can mean assembly, but depending on context it may also be translated as:

• meeting
• general meeting
• shareholders’ meeting
• assembly session

In formal or legal/corporate contexts, assembleia is very common. So ata da assembleia often means the official minutes of a formal meeting.

Because after existential haver (há), Portuguese often uses the noun without an article when talking about the existence of something in a general sense.

So:

• há quórum = there is quorum
• há problemas = there are problems
• há uma solução = there is a solution

You can sometimes use an article depending on meaning, but há quórum is the normal way to say there is quorum / a quorum is present.

Here há is the verb haver used in its existential sense, meaning there is / there are.

So:

• há quórum = there is quorum

This is a very standard and formal way to express existence.

Comparison:

• há quórum — formal, standard, very natural in written language
• tem quórum — common in spoken Brazilian Portuguese, but less formal
• existe quórum — possible, but usually less idiomatic in this kind of sentence

In a formal sentence about meeting minutes, há quórum is exactly what you would expect.

Good question. Há stays in the third-person singular because existential haver is impersonal in Portuguese.

That means it does not agree with the noun that comes after it.

So Portuguese says:

• há quórum
• há pessoas na sala
• há problemas

Not:

• hão quórum
• hão pessoas
• hão problemas

Even if the thing mentioned is plural, existential haver stays singular.

Here que means that and introduces a subordinate clause.

Structure:

• A ata da assembleia mostra = The minutes of the assembly show
• que há quórum = that there is quorum

So que links the two parts:

• shows that there is quorum

This is very common in Portuguese:

• Ela disse que vai chegar cedo.
• O relatório mostra que houve erro.

Mostra is the present tense of mostrar (to show).

In Portuguese, the present can be used very naturally when talking about what a document says or shows right now:

• O relatório mostra... = The report shows...
• A ata mostra... = The minutes show...

Even if the document was written in the past, it still shows something now as a current fact contained in the document.

A simple approximation for a native English speaker is:

• há ≈ ah
• quórum ≈ KWO-rum

A few useful notes:

• há has an acute accent, showing stress: HÁ
• quórum is stressed on the first syllable: QUÓ-rum
• the quó sounds like kwo

In Brazilian Portuguese, the whole part há quórum is typically pronounced smoothly together.

Because the stressed syllable is the first one: QUÓ-rum.

The accent mark shows where the stress goes. Without it, Portuguese spelling rules might lead you to expect a different stress pattern.

Also, quórum is a learned borrowing used in formal contexts, especially legal, parliamentary, academic, and corporate language.

It is common mainly in formal or institutional contexts, such as:

• meetings
• committees
• corporate boards
• academic councils
• legislative sessions

People use it when they mean the minimum number of participants needed for a meeting or vote to be valid.

So in a sentence about meeting minutes, quórum is perfectly normal.

Yes, that is grammatically correct, and people would understand it.

But A ata da assembleia mostra que há quórum sounds more natural and standard in formal written Portuguese.

So:

• há quórum — most idiomatic here
• existe quórum — correct, but a bit less natural in this context

In current Brazilian Portuguese spelling, the standard form is assembleia without an accent.

The older spelling assembléia was used before the spelling reform, but today the standard form is:

• assembleia

So the sentence is using the modern standard spelling.
