A declarative sentence (frase declarativa) makes a statement. It asserts that something is the case — or, in its negative form, that something is not the case. This is the workhorse sentence type of any language: most of what you read in a newspaper, say in conversation, or write in a message is a declarative. Portuguese declaratives are superficially similar to English ones, but three features set them apart: they can freely drop the subject pronoun, they use não before the verb to negate, and they admit more word-order flexibility than English when you want to shift emphasis.
What makes a sentence declarative
Declaratives are defined by three features that work together:
- Function: they make a statement rather than ask a question, give a command, or express surprise.
- Intonation: they end with a falling pitch in speech, written as a period (.).
- Word order: they use the neutral Subject-Verb-Object (SVO) pattern as the default, though Portuguese tolerates deviations for stylistic effect.
O João estuda português.
João studies Portuguese.
A minha irmã trabalha num banco no Porto.
My sister works at a bank in Porto.
Os miúdos estão no parque.
The kids are at the park.
Each of these makes a plain statement, ends in a period, and puts the subject before the verb. That's the default declarative shape.
Affirmative vs. negative declaratives
A declarative can assert that something is the case (affirmative) or that something is not the case (negative). Portuguese marks negation by placing não directly before the verb.
Ela fala francês.
She speaks French.
Ela não fala francês.
She doesn't speak French.
Nós vamos ao supermercado.
We're going to the supermarket.
Nós não vamos ao supermercado hoje.
We're not going to the supermarket today.
Notice that Portuguese needs no auxiliary verb (no equivalent of English do/does) — não glues straight onto the finite verb. This makes negation simpler than in English, but it also means you cannot separate não from the verb. Placing anything between them (adverb, object pronoun that is not a clitic) is ungrammatical.
For the full treatment of negation — double negation, negative words, and clitic interactions — see the dedicated negative-sentences page.
Pro-drop: the invisible subject
Portuguese is a pro-drop (null-subject) language. Because the verb ending already tells you who the subject is, the subject pronoun can — and usually should — be omitted in ordinary statements.
Falo português.
I speak Portuguese.
Moras em Lisboa?
Do you live in Lisbon?
Estamos cansados.
We're tired.
Falo can only mean "I speak" (the -o ending marks first-person singular). Including eu is not wrong, but it feels like you're emphasising — "I speak Portuguese (whoever else does or doesn't)." In English the subject is obligatory; in Portuguese it is informational, used when you need to contrast or clarify.
Eu gosto de café, mas ela prefere chá.
I like coffee, but she prefers tea. (contrast — both pronouns kept)
Ele não sabe, mas nós sabemos.
He doesn't know, but we do. (contrast)
In lists, contrasts, and answers to "who?" questions, the subject pronoun reappears. In neutral statements, it disappears.
SVO as the default
Declaratives default to Subject-Verb-Object order, the same as English.
| Subject | Verb | Object / Complement |
|---|---|---|
| O meu pai | lê | o jornal todas as manhãs. |
| Eles | compraram | uma casa nova. |
| A Ana | é | médica. |
O meu pai lê o jornal todas as manhãs.
My father reads the paper every morning.
Eles compraram uma casa nova.
They bought a new house.
A Ana é médica.
Ana is a doctor.
Note the definite article before personal names (o João, a Ana) — this is standard in European Portuguese in declarative statements about people, and its absence sounds formal or cold in everyday speech.
Word-order flexibility for emphasis
Although SVO is the default, Portuguese is far more flexible than English. You can shift elements around to foreground what matters. Three patterns are especially common in declaratives:
Postposed subject (VS)
With unaccusative and existential verbs (chegar, vir, acontecer, haver, faltar, sobrar), the subject often appears after the verb. This is neutral, not marked — it reflects how information is packaged.
Chegaram três encomendas hoje.
Three packages arrived today.
Faltam dois alunos.
Two students are missing.
Aconteceu uma coisa estranha.
Something strange happened.
In English, you would almost always front the subject ("Three packages arrived"). In Portuguese, postposing the subject is natural with these verbs, especially when the subject is new information.
Fronted object for contrast
You can move an object to the front of the sentence to emphasise it, usually with a pause or a resumptive clitic.
Esse livro já li.
That book I've already read.
A tua irmã, vi-a ontem na baixa.
Your sister, I saw her yesterday downtown.
This is called topicalisation and it's common in spoken Portuguese. The resumptive clitic (-a in the second example) is needed when the fronted element is a specific, definite direct object.
Adverbial fronting
Time, place, and manner adverbials freely move to the front of a declarative for emphasis or cohesion with preceding sentences.
Ontem fomos ao cinema.
Yesterday we went to the cinema.
Em Lisboa, come-se muito peixe.
In Lisbon, people eat a lot of fish.
Com muito cuidado, abriu a caixa.
Very carefully, he opened the box.
The copula: declaratives with ser and estar
A great many declaratives describe states rather than actions. Portuguese splits "to be" into ser and estar, and this choice shapes most A1–A2 declaratives. The contrast gets its own dedicated pages, but at minimum:
Sou português.
I'm Portuguese. (permanent identity — ser)
Estou cansado.
I'm tired. (temporary state — estar)
A sopa é de legumes.
The soup is vegetable. (inherent — ser)
A sopa está fria.
The soup is cold. (current state — estar)
Both sentences are declaratives; the copula choice is a lexical decision, not a sentence-level one.
Punctuation and capitalisation
A written declarative ends with a period. The first word is capitalised. Portuguese does not capitalise eu (the first-person pronoun), unlike English I.
Eu acho que eles têm razão.
I think they're right.
Quando cheguei a casa, eu já estava exausto.
By the time I got home, I was already exhausted.
The only context in which eu gets capitalised is at the start of a sentence — by the general rule, not because it's eu.
Declaratives in dialogue and writing
Here are two short stretches of everyday Portuguese, each built entirely from declaratives. Read them to get a sense of how declaratives string together in real prose.
Conversational:
Ontem fui ao supermercado. Comprei fruta e pão. No caminho de volta, encontrei a vizinha. Conversámos um bocadinho.
Yesterday I went to the supermarket. I bought fruit and bread. On the way back, I ran into the neighbour. We chatted a bit.
Narrative / journalistic:
O comboio saiu atrasado de Santa Apolónia. A companhia alegou problemas técnicos. Muitos passageiros perderam ligações.
The train left Santa Apolónia late. The company cited technical problems. Many passengers missed connections.
Note how pro-drop works across sentences: once eu is established as the subject in conversation, it disappears from later sentences. In the journalistic paragraph, subjects shift (o comboio → a companhia → muitos passageiros), so each is spelled out.
Common Mistakes
❌ Eu sou cansado.
Incorrect — cansado is a temporary state.
✅ Estou cansado.
I'm tired.
Using ser for temporary states is the classic anglicism: English has only "to be," so learners overextend ser. Rule of thumb: physical and emotional states almost always take estar.
❌ Eu eu vou para casa.
Incorrect — redundant subject.
✅ Vou para casa.
I'm going home.
Including the pronoun twice or even once in every sentence sounds unnatural in Portuguese. Drop eu unless you're emphasising or contrasting.
❌ Ela trabalha em um escritório.
Common Brazilianism — avoid in European Portuguese.
✅ Ela trabalha num escritório.
She works in an office.
European Portuguese contracts em + um/uma into num/numa obligatorily. The uncontracted form sounds Brazilian.
❌ O João é estudante e ele é inteligente.
Stilted — don't repeat the subject.
✅ O João é estudante e é inteligente.
João is a student and is intelligent.
Once the subject is established, let pro-drop do the work. Re-stating ele every time makes the prose sound mechanical.
❌ A Ana não sabe a sua opinião.
Ambiguous — sua could mean 'her own' or 'your' (formal).
✅ A Ana não sabe a opinião dela. / A Ana não sabe a opinião do senhor.
Ana doesn't know her opinion. / Ana doesn't know your (formal) opinion.
In declaratives about third persons, the possessive seu / sua is ambiguous between "his/her" and "your" (formal). Use dele / dela or an explicit address form when you need to disambiguate.
Key Takeaways
- A declarative makes a statement, ends with a period, and defaults to SVO.
- Subject pronouns are usually dropped — Portuguese is pro-drop.
- Negation: não sits directly before the verb (no do/does).
- SVO is flexible — fronted adverbials, postposed subjects, and topicalisation all produce natural declaratives.
- Every declarative with a "be"-verb forces you to pick ser or estar; get this habit early.
