Portuguese Articles Definite and Indefinite

Portuguese Articles | Definite and Indefinite

Today I will write about the Portuguese definite and indefinite articles. One thing you have to know is that in European Portuguese, we always use and abuse these grammar particles.

Like in English, we use the indefinite articles to speak about something that we are presenting in the discourse for the first time.

On the other hand, the definite articles are here to tell us about some noun that we already know. They introduce something more specific.

Let us take a look at the following example:

ex: “Tenho um livro bonito” (“I have a beautiful book”); “O livro é branco” (“The book is white“).

In the example above, while in the first sentence we did not know which book we were talking about, since it was introduced for the first time then and there, in the second part we already know we are speaking about a specific book, i.e., the book I have, which is beautiful. Therefore, in the first sentence we use an indefinite article, while in the second one we use a definite article.

Until here, it seems simple enough. Right?

Portuguese Definite Articles

In English there is only one definite article – “the” – and two indefinite articles – a and an – but in Portuguese there are many more. In fact, we have different articles for every gender (feminine or masculine) and number (singular or plural). What I mean is that if a noun is masculine and singular, it will take a different definite or indefinite article than if it is a feminine singular, for example.

Another thing that you, my dear students, have to understand, is that in Portuguese almost EVERY noun is assigned a gender. It is either masculine or feminine. There are some exceptions, but they are really just only a few.

So, even if it does not make sense to you (probably because your language does not assign a gender to things) that a pen is feminine, in Portugal we really look at a pen and see a feminine object (at least from my experience and by questioning other people).

This happens because in our language, the word “pen” is feminine and we say “a caneta”. See what I did there? I wrote “the pen” but the “the” part is feminine and singular in this case, because the noun is feminine and singular as well.

If I were to say “the pens”, however, I would have to change the definite article into “as”, because that is the article corresponding to the feminine, plural nouns.

To give you an overview of all the definite articles, here is a table I made to make it easier:

Portuguese Definite Articles
Masculine Feminine
Singular o a
Plural os as

Definite articles in Portuguese – Exercises:

Modern House

1. So, now that you know this chart, and that you know that “casa” (house) is a feminine singular word in Portuguese, which of the above-written articles would you choose?

  1. o casa
  2. a casa
  3. os casa
  4. as casa

2. In the same way, knowing that “barco” (boat) is a masculine noun in European Portuguese, which of the articles in the table would you choose?

  1. o barco
  2. a barco
  3. os barco
  4. as barco

Can you put them into the plural form?

Just write down what you think is the right choice in the comment section below and keep reading to find the correct answers.

By now what you must be thinking is, “but how can I know which article to assign to a noun? How can I know if a pen is feminine or masculine (well, this one is easy cause I already told you)?”

Well, the truth is, there are some rules you can follow, but all those rules will have exceptions. However, if you follow them there will be a chance that you will be right.

RULES for assigning gender in Portuguese:

#Masculine nouns

– Words ending in “o” are generally masculine.

Examples: “o carro”, “o cavalo”, “o quadro”;

– Words ending in “ama” or “ema” are also generally masculine.

Examples: “o programa”, “o pijama”, “o tema”, “o problema”;

#Feminine nouns

– Words ending in “a” are generally feminine.

Examples: “a casa”, “a banana”, “a cama”;

– Words ending in “ção“, which have the translation to words ending in “ion” in English (like a tradução – the translation) are generally feminine.

Examples: “a intenção” (in English, the intention), “a poluição” (in English, the pollution);

– Words that end in “gem” or “ade” are also generally feminine;

Examples: “a margem”, “a espionagem”, “a garagem”.


Portuguese Indefinite Articles

The indefinite articles work exactly in the same way as the definite articles. What I mean is a noun that is feminine and singular, will take the equivalent indefinite article.

In this case, if we want to say “a pen” (we already know that pen is feminine and singular), then we will say “uma caneta”. “Uma” is then the indefinite article that corresponds to the feminine, singular nouns.

If, on the other hand we wanted to make it plural, we would have to use the article “umas”, which is the article one should use for feminine, plural nouns.

I also made a table to help you with your indefinite articles. Take a look:

Portuguese Indefinite Articles
Masculine Feminine
Singular um uma
Plural uns umas

Indefinite articles in Portuguese – Exercises:

3. So, let´s try the same game we tried above with the definite articles? As you already know, “casa” is feminine and also singular. So if you wanted to say “a house” this time, which one of the following numbers would you choose?

  1. um casa
  2. uma casa
  3. uns casa
  4. umas casa

2 boats in the sea

4. In the same way, knowing that “barco” (boat) is a masculine and singular noun in European Portuguese, which of the following lines would you choose?

  1. um barco
  2. uma barco
  3. uns barco
  4. umas barco

Can you put them into the plural form?

Again, just write them down in the comment section below and continue reading, because the answer will come at the end.

There is just one or two more details I want to point out about the indefinite articles. While “um” and “uma” mean “a/an”, “uns” and “umas” mean “some” in English. So, if I say, “Eu vi umas casas”, that means that “I saw some houses”.

There is also another way to say this, which is with “algum/alguns/alguma/algumas”, but you ought not to worry about it now. Just know that “uns” and “umas” mean “some”, instead of “a/an”.

Another thing to bear in mind is that if you use a masculine, singular definite article with a certain noun, that means that the noun is masculine and singular and that will remain like that when you extend it to the use of the indefinite articles and vice-versa.

So, if you say “o carro” (the car), because you know that “carro” is a masculine, singular word, then you will also have to use the indefinite article which is masculine and singular “um carro” (a car).


Alright, folks! If you made it till here, I want to congratulate you! You have just learnt something new about the amazing European Portuguese language and I am proud of you! Keep going and exploring around to know more!

  3. ola Mia!…thank you for the Portuguese lesson.

    1. Olá Ileyton 🙂
      you are welcome!

  4. Great article. There are several nouns for which the assigned genders just don’t make sense. For example, a woman’s dress, vestido, is masculine. Perhaps it has to do with clothing worn many years ago. But, a word that seems the most feminine of all words, the egg, is a masculine word. Do you have any insight as to why that is? Thanks.

    1. Olá Mark!
      That is a really good question. I don´t have a general answer, but I guess it depends on the way the words developed through the years.
      In the case of the word “egg”, “o ovo”, I guess it might have to do with the fact that generally words ending in “o” are masculine. I guess that could be an explanation =) I am sorry I cannot give a more sure answer, but this has to do with the development of the languages and I am not an expert in that, although I have some insights.
      I hope this helped nevertheless.
      Thank you so much for your interest.
      Kind regards,

  5. Obrigada .Gostei e aprendi algumas dicas.

    1. Obrigada eu!

  6. Hi Mia,

    Nice article about articles! Just a small correction: the titel of the second table is ‘definitie articles’ but should be ‘indefinite articles’. Keep up the good work!

    Moreover I wonder why somewhere in history people decided (or why it emerged over time) that there should be masculin and feminin in language, because to me it seems an unnecessary complication .. Do you have any idea?

    Kind regards,

    1. Olá again Teun 🙂

      Thank you for your correction,(it was a typo, I’ll change it:)
      About why words are feminine and masculine… well, I think it comes from the marking of cases in Latin..the basis language for Portuguese.
      It seems a bit complicating, that’s true 🙂 I’m sorry about that he he. But just think it could be worse. There are languages that have three (or maybe more?) genders…
      I hope you can tackle these soon 🙂


  7. It was good for me Mia. Thanks to you. I learnt more today, especially about male and female words in Portuguese.

  8. Hi Mia,
    You’ve got a nice article here. I enjoyed reading your post and picked a few tips on speaking the European Portuguese. I live in Italy and I must say that the Italian language and Portuguese are similar. a casa, La casa. O barco, La barca. It was fun learning from you , you made it seem so easy. It is always interesting when we learn a new language but some teachers make it look hard. Thanks for the post

    1. Thank you for your comment. I am glad you enjoyed it. I always try to write articles that help people understand the rules of the language in an easy (and fun) way.

      Italian and Portuguese ARE quite similar, you are right =) They belong to the same group of languages – Romance languages – and they have the same roots – latin.

      Please keep coming back and you might enjoy the other articles and the material I am constantly uploading. Soon there will be videos =)

      See you soon!
