A síndica convocou a assembleia de condomínio.

Síndica is the feminine form of síndico.

In Brazil, a síndico/síndica is usually the person who manages a residential building or housing complex — something like a building manager, property manager, or the elected head of a condo association / HOA, depending on the context.

So:

• o síndico = a male manager/administrator of the condominium
• a síndica = a female manager/administrator of the condominium

It is a very common word in Brazilian apartment-building life.

Here, a is the feminine singular definite article, meaning the.

So:

• a síndica = the female condo manager
• not just a manager in the general sense, but a specific one already known in context

Portuguese uses definite articles more often than English does, especially before nouns referring to specific people in a situation.

Convocou is the 3rd person singular of the preterite of convocar.

• convocar = to call, summon, convene
• ela convocou = she called / she convened

Why preterite? Because it describes a completed past action:

• A síndica convocou... = The manager called/convened...

This is the tense you typically use for a single finished event in the past.

No. In Portuguese, verbs do not change according to the gender of the subject.

So:

• A síndica convocou = the female manager called
• O síndico convocou = the male manager called

In both cases, the verb is still convocou because the subject is 3rd person singular. Gender is shown by the noun/article (a síndica / o síndico), not by the verb.

Because in this sentence assembleia is the direct object of convocou.

• convocar algo = to convene/call something
• no preposition is needed before the object

So:

• convocou a assembleia = convened the meeting

You would get à only if there were a preposition a plus the article a.

For example:

• foi à assembleia = went to the meeting
  (a preposition + a article = à)

But here:

• convocou a assembleia
  there is only the article a, not a preposition

Assembleia de condomínio is a noun phrase meaning a condo/condominium meeting, especially an official meeting of residents/owners.

Breaking it down:

• assembleia = assembly, meeting
• de condomínio = of condominium / condo-related

In practice, this expression refers to the formal meeting where building residents or owners discuss rules, budgets, maintenance, elections, and so on.

So de condomínio works a lot like a classifier here, telling you what kind of meeting it is.

Both can exist, but they are not exactly the same.

• assembleia de condomínio = a condominium meeting / a condo association meeting
  This sounds more like the type of meeting.
• assembleia do condomínio = the meeting of the condominium
  This points more directly to a specific condominium.

So in your sentence, assembleia de condomínio feels a bit like a set expression: a condo meeting.

If someone said A síndica convocou a assembleia do condomínio, that would also be very natural, especially if everyone already knows which building is being discussed.

The accent marks show the stressed syllable and follow Portuguese spelling rules.

• síndica → stress on sín
• condomínio → stress on ní

These accents help indicate pronunciation and distinguish the normal stress pattern.

For an English speaker, a rough guide would be:

• síndica ≈ SEEN-jee-kah or SIN-jee-kah depending on accent
• condomínio ≈ kon-doh-MEE-nee-oh

Exact pronunciation varies a bit by region, but the written accents tell you where the stress goes.

Modern Brazilian Portuguese writes it as assembleia without an accent.

Older spelling used assembléia, but after the spelling reform, the accent was removed.

So today the standard spelling is:

• assembleia

This is something learners often notice because older texts, signs, or materials may still show the old spelling.

Yes. This is the standard Portuguese order:

• Subject + verb + object
• A síndica
  • convocou
    • a assembleia de condomínio

That makes it a very straightforward sentence.

Portuguese can sometimes change word order for emphasis, but this version is the most neutral and natural one for everyday use.

In normal standard Portuguese, that would sound incomplete or unnatural in most contexts.

The full version with articles is much more natural:

• A síndica convocou a assembleia de condomínio.

Portuguese generally likes articles more than English does, especially with specific nouns. In headlines, notes, or very informal shorthand, articles may be dropped, but in regular speech and writing, they are usually kept here.

Not exactly.

• chamar = to call
• convocar = to summon, convene, officially call together

In the context of meetings, convocar is much more precise and formal. It is the natural verb for officially scheduling or calling a meeting.

So:

• convocar a assembleia = to officially convene the meeting

That is why convocou fits this sentence especially well.
