Artigos em Português — A2

All eight articles at a glance

Portuguese has four definite articles (equivalent to English the) and four indefinite articles (equivalent to a / an / some). Each one must agree in gender (masculine / feminine) and number (singular / plural) with the noun it modifies.

Artigos Definidos — "the"

o masc. singular o carro

a fem. singular a casa

os masc. plural os carros

as fem. plural as casas

Artigos Indefinidos — "a / some"

um masc. singular um gato

uma fem. singular uma cadeira

uns masc. plural uns amigos

umas fem. plural umas amigas

O, A, Os, As — talking about something specific

Use the definite article when both you and your listener already know which thing you are talking about — it's specific, identified. In this sense it works just like English the.

Artigo	Português	English
o	O carro é novo.	The car is new.
a	A casa é azul.	The house is blue.
os	Os gatos estão dormindo.	The cats are sleeping.
as	As portas estão fechadas.	The doors are closed.

Where Portuguese uses the — but English doesn't

This is the most common source of mistakes for English speakers. Portuguese uses the definite article in several situations where English uses no article at all.

🍂 Seasons (estações do ano)

A primavera é linda. / Eu amo o inverno.

Spring is beautiful. / I love winter.
🍽️ Meals (refeições)

O almoço está pronto! / O jantar está servido.

Lunch is ready! / Dinner is served.
🎄 Holidays & celebrations

O Natal é muito celebrado no Brasil. / A Páscoa é em abril.

Christmas is very celebrated in Brazil. / Easter is in April.
💧 Uncountable nouns (água, sal, beleza…)

O sal é um tempero básico. / A água da torneira é potável.

Salt is a basic seasoning. / Tap water is drinkable.
🌎 General categories (all people, all Brazilians…)

Os brasileiros falam português. / As pessoas aqui são simpáticas.

Brazilians speak Portuguese. / People here are friendly.
🔢 "Ambos / Ambas" — always takes an article

Ambas as cidades são lindas. / Ambos os projetos foram aprovados.

Both cities are beautiful. / Both projects were approved.

💡 Quick pattern

If a noun represents a whole category or a general concept in Portuguese, it almost always needs a definite article. English skips it — Portuguese doesn't.

Special cases — names, countries, cities, possessives

These are specific rules that do not have direct equivalents in English. Read each one carefully.

👤 People's names

Using an article before a first name is optional in Brazilian Portuguese. It signals familiarity and is very common in everyday conversation — especially in São Paulo and Rio.

A Paula é brilhante.
O Antônio ligou pra você?

Both forms are correct. In formal writing, skip the article.

🌎 Countries

Countries have gender in Portuguese and most take a definite article. Learn the gender with the name!

O Brasil · A Argentina
A França · Os Estados Unidos

⚠️ Exception: Portugal — no article!
"Portugal fica na Europa." ✓

🏙️ Cities

Cities usually have no article in Portuguese. They are treated as proper names without gender.

São Paulo · Fortaleza · Salvador · Curitiba

⚠️ Exception: O Rio de Janeiro
Rio always takes the masculine article.

🏠 Possessives

The article before a possessive is optional — both forms are equally correct in Brazilian Portuguese.

O meu nome é Lucas. ✓
Meu nome é Lucas. ✓

In practice, Brazilians often drop the article before possessives in informal speech.

🇧🇷 Regional variation — articles before names

The habit of saying a Paula or o João is most common in São Paulo and Rio de Janeiro. In northeastern cities like Recife and Fortaleza, people more often skip the article. Both forms are grammatically correct — the article before a name is always optional.

Um, Uma, Uns, Umas — something non-specific

Use the indefinite article when you are talking about one item among many, or something mentioned for the first time that the listener cannot identify yet. The singular forms equal English a / an; the plurals equal some.

Artigo	Português	English
um	Eu tenho um gato.	I have a cat.
uma	Ela comprou uma cama nova.	She bought a new bed.
uns	Convidei uns amigos para a festa.	I invited some friends to the party.
umas	Trouxe umas flores do mercado.	I brought some flowers from the market.

📐 Uns / Umas = approximate quantity

The plural indefinite articles also express an approximate number — like around or about in English:

Acho que ele tem uns 60 anos. — I think he is around 60 years old.
Umas 30 pessoas virão à festa. — About 30 people will come to the party.
Esse cinto custou uns R$ 200. — This belt cost around R$ 200.

⚠️ Important rule — no article before professions

When you state someone's profession, nationality, or religion, do not use an indefinite article in Portuguese. This is one of the most common mistakes for English speakers.

English (uses "a")	Português (no article)
I am a teacher.	Eu sou professora. ✓ ✗ Eu sou uma professora. (wrong)
He is a doctor.	Ele é médico. ✓ ✗ Ele é um médico. (wrong)
She is a lawyer.	Ela é advogada. ✓
They are Brazilian.	Eles são brasileiros. ✓

⚠️ When CAN you use the article before a profession?

Adding um/uma before a profession is possible, but it shifts the meaning — it implies a quality or emphasis: "Ela é uma médica incrível" (She is an incredible doctor). Without the article, you are simply stating the profession. In most situations, drop it.
