If you are learning Portuguese, understanding definite and indefinite articles is one of the first (and most important) grammar steps. Don’t worry — it’s much easier than it sounds!
In this guide, you’ll learn the difference between definite and indefinite articles in Portuguese, how to use them in real sentences, and how they change depending on gender and number. Let’s make it simple and fun!
What Are Articles?
Articles are small words that come before nouns to show whether we are talking about something specific or general.
In English, you already know them:
- The → definite article
- A / An → indefinite articles
Portuguese works the same way, but the articles agree with gender (masculine/feminine) and number (singular/plural) of the noun.
Definite Articles in Portuguese
Definite articles talk about specific things — things both the speaker and listener know about.
| English | Portuguese (Masculine) | Portuguese (Feminine) |
|---|---|---|
| the | o (singular) / os (plural) | a (singular) / as (plural) |
Examples:
- O carro é novo. → The car is new.
- A menina é simpática. → The girl is nice.
- Os livros são interessantes. → The books are interesting.
- As casas são grandes. → The houses are big.
💡 Tip: In Portuguese, articles are often used more frequently than in English. For example, you might say “O João é meu amigo” (literally “The João is my friend”) — something you would never say in English.
Indefinite Articles in Portuguese
Indefinite articles talk about unspecified or general things — something you’re mentioning for the first time.
| English | Portuguese (Masculine) | Portuguese (Feminine) |
|---|---|---|
| a / an | um (singular) / uns (plural) | uma (singular) / umas (plural) |
Examples:
- Um carro está na rua. → A car is on the street.
- Uma menina está a cantar. → A girl is singing.
- Uns livros estão na mesa. → Some books are on the table.
- Umas casas bonitas! → Some beautiful houses!
Difference Between Definite and Indefinite Articles in Portuguese
| Situation | Example with Definite Article | Example with Indefinite Article |
|---|---|---|
| Talking about something known | O gato está no sofá. (The cat is on the sofa.) | Um gato está no sofá. (A cat is on the sofa.) |
| Talking about general facts | As crianças gostam de brincar. (Children like to play.) | Umas crianças estavam a brincar. (Some children were playing.) |
The difference is simple:
- Definite article = specific (you know which one)
- Indefinite article = general (any one)

Brazilian vs European Portuguese
The rules are the same, but pronunciation and usage differ slightly.
In Brazilian Portuguese:
- Articles are pronounced clearly: “o” sounds like “oo”, “a” sounds like “ah”.
- Example: O menino é inteligente.
In European Portuguese:
- The “o” is shorter and often sounds like “u”: “u menino é inteligente” (Lisbon accent).
- Example: A escola é perto.
👉 Both are correct! Listening to native speakers helps you catch these small pronunciation details. You can find many definite and indefinite articles in Portuguese audio examples on YouTube or language podcasts.
