Os condôminos deliberam sobre a previsão orçamentária.

Condôminos are the people who legally own units in a condominium or apartment building. In Brazilian usage, it usually refers to unit owners/co-owners, not just anyone who lives there.

So in a condo context:

• condômino = condo owner / co-owner
• morador = resident
• inquilino = tenant

A tenant may live in the building, but technically is not usually a condômino unless they own the unit.

Os is the masculine plural definite article, meaning the.

It agrees with condôminos, which is a masculine plural noun:

• o condômino = the condo owner
• os condôminos = the condo owners

Portuguese uses articles more often than English does, so Os condôminos sounds natural here.

Deliberam is the present indicative, third person plural form of deliberar.

So it corresponds to:

• they deliberate
• they discuss formally
• they decide on, depending on context

Conjugation in the present:

• eu delibero
• você/ele/ela delibera
• nós deliberamos
• vocês/eles/elas deliberam

Here, deliberam matches os condôminos because the subject is plural.

It is understandable and correct, but it sounds formal and often appears in administrative, legal, or meeting-related contexts.

You are likely to see it in:

• condo association minutes
• official notices
• legal or bureaucratic writing
• meeting agendas

In more everyday speech, Brazilians might more often say:

• discutir
• decidir
• conversar sobre
• votar

So deliberam feels more formal than casual conversation.

Because deliberar sobre is a normal structure meaning to deliberate about/on something.

So:

• deliberar sobre um assunto = to deliberate on a matter
• deliberar sobre a previsão orçamentária = to deliberate on the budget forecast

You generally would not say deliberar a previsão orçamentária in this meaning. The preposition sobre is important here.

It refers to a budget forecast, budget estimate, or projected budget.

The noun previsão means something like:

• forecast
• projection
• estimate
• expectation

And orçamentária comes from orçamento (budget), so the whole phrase is about the expected or planned financial figures.

In a condo context, this usually means the projected budget for future expenses, fees, maintenance, and so on.

Because orçamentária is an adjective agreeing with previsão, and previsão is a feminine singular noun.

Agreement in Portuguese matters:

• previsão = feminine singular
• therefore: orçamentária = feminine singular

If the noun were masculine, the adjective would change:

• planejamento orçamentário = budget planning

So the ending changes to match the noun it describes.

Portuguese often omits subject pronouns when the verb already makes the subject clear.

Here, deliberam already tells you the subject is they, and the noun phrase Os condôminos is explicitly stated anyway.

So Portuguese normally says:

• Os condôminos deliberam...

not:

• Os condôminos eles deliberam...

Adding eles here would usually sound unnecessary or marked unless you wanted special emphasis.

A is the feminine singular definite article, meaning the.

It agrees with previsão, which is feminine:

• a previsão
• a previsão orçamentária

So the sentence has:

• Os = the, masculine plural, for condôminos
• a = the, feminine singular, for previsão

This kind of article-noun agreement is a basic and very important part of Portuguese grammar.

A simple approximate guide:

• condôminos ≈ kon-DOH-mee-noos
• previsão ≈ preh-vee-ZOWN nasalized
• orçamentária ≈ or-sah-men-TAH-ree-ah

A few important pronunciation points:

• ô in condôminos is a closed o sound.
• ão in previsão is nasal and does not sound like English own exactly.
• ç in orçamentária sounds like s.
• The stress in orçamentária falls on tá because of the accent: or-ça-men-tá-ri-a.

The accent marks help show pronunciation and stress.

For example:

• condôminos: the ô shows a stressed, closed vowel sound
• previsão: the ã shows nasalization
• orçamentária: the á shows the stressed syllable

In Portuguese, accents are not optional decoration. They are part of correct spelling and often tell you how a word is pronounced.

Yes. The original sentence sounds formal and administrative. In more everyday Brazilian Portuguese, people might say things like:

• Os moradores discutem o orçamento.
• Os condôminos discutem a previsão do orçamento.
• Os condôminos vão decidir sobre o orçamento.

These alternatives may sound more conversational, while Os condôminos deliberam sobre a previsão orçamentária sounds like something from meeting minutes or an official document.

The sentence uses the most neutral word order in Portuguese:

• Subject + verb + prepositional phrase

So:

• Os condôminos = subject
• deliberam = verb
• sobre a previsão orçamentária = complement

You could rearrange parts in some contexts for emphasis, but the original order is the most standard and natural for formal writing.

Here, sobre means about or on, not over in a physical sense.

So in this sentence, it has the idea of:

• deliberating about
• deliberating on
• discussing with respect to

Portuguese sobre has several meanings depending on context, but here it is the abstract/topic-related one.
