Cabe à administradora lavrar a ata da assembleia.

Here, cabe comes from caber, but it does not mean to fit.

In the pattern caber a alguém + infinitive, it means things like:

• to be up to someone
• to fall to someone
• to be someone’s responsibility

So Cabe à administradora lavrar a ata da assembleia means that this task is the administrator’s responsibility.

This use is quite common in formal, legal, and administrative Portuguese.

Because this is a case of crase.

The verb pattern is caber a alguém. That gives you the preposition a.

Then administradora is a feminine noun and here it takes the feminine article a.

So you get:

• a
  • a administradora = à administradora

That grave accent in à shows the contraction of:

• preposition a
• article a

A useful test is to switch to a masculine word:

• Cabe ao administrador...

Since ao is clearly a + o, that confirms that the feminine form should be à.

The subject is the infinitive phrase:

• lavrar a ata da assembleia

In other words, writing up the minutes of the meeting is the thing that falls to the administrator.

Portuguese often uses this structure where an infinitive phrase functions as the subject:

• Cabe à administradora lavrar a ata
• literally, something like To draft the minutes belongs to the administrator’s responsibility

In natural English, we usually restructure it as:

• It is up to the administrator to draft the minutes
• The administrator is responsible for drafting the minutes

So the sentence does have a subject, but it is not a noun like a administradora.

Yes, lavar means to wash, but this sentence uses lavrar, which is a different verb.

In formal and legal Portuguese, lavrar uma ata means:

• to draw up the minutes
• to draft the minutes
• to formally write up the record

It is a fixed, formal expression.

So:

• lavrar a ata = prepare the official written minutes of a meeting

In less formal language, you might also hear:

• redigir a ata
• fazer a ata
• escrever a ata

But lavrar a ata sounds especially official and bureaucratic.

An ata is the official written record of what happened in a meeting.

In English, the usual translation is:

• minutes
• sometimes meeting minutes

So a ata da assembleia is the formal document recording the decisions, discussions, and results of the assembly or meeting.

This is a very common word in business, legal, corporate, and condominium contexts in Brazil.

Because da is the contraction of:

• de
  • a

So:

• a ata da assembleia = the minutes of the assembly

Since assembleia is a feminine singular noun, de a assembleia becomes da assembleia.

This kind of contraction is very common in Portuguese:

• de + o = do
• de + a = da
• de + os = dos
• de + as = das

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

Older spelling often showed:

• assembléia

After the spelling reform, words like this lost the accent.

So if you see both forms, the modern standard is:

• assembleia

That is the expected spelling in contemporary Brazilian Portuguese.

It can mean either, depending on context.

It may refer to:

• a female administrator/manager
• an administration company, especially in property or condominium contexts

In Brazil, in contexts involving buildings, condominiums, or associations, a administradora often means the management company that handles administrative matters.

So without more context, the sentence could mean either:

• it is the female administrator’s responsibility or
• it is the management company’s responsibility

Context tells you which one is meant.

Yes, this sentence is quite formal and administrative.

The combination of:

• cabe a alguém
• lavrar a ata

makes it sound official, legal, or bureaucratic.

In more everyday Brazilian Portuguese, people might say something like:

• A administradora é responsável por fazer a ata da assembleia
• A administradora tem que redigir a ata da assembleia
• A administradora deve fazer a ata da assembleia

These versions are more direct and conversational, while the original sentence sounds more like something from rules, bylaws, or official instructions.
