8 Situations to Use the Verb SER in Portuguese

Portuguese lesson on how to use the Verb SER in Portuguese

The correct use of the verb Estar and the verb Ser in Portuguese is a topic that causes learners of Portuguese a lot of trouble. Both verbs mean the same thing in English: To be.

Using these verbs is one of the first topics that you cover when you start learning Portuguese. It’s also a topic that will probably offer you some challenge throughout your Portuguese speaking journey, even when you are happily fluent in Portuguese.

In this lesson I will cover the main uses of Ser in Portuguese. I talk about Estar here.

At the end of this Portuguese lesson I offer you practice exercises.

A Word of Encouragement

I’d like to give you my perspective on learning Ser and Estar. I hope to offer you some encouragement.

  • You may memorize all the rules and still make mistakes. This is because when you are in the middle of a spontaneous conversation, your brain is working too fast to stop and go look for rules. Be patient with your brain. It’s an amazing machine.
  • Even advanced speakers you will mix up the verbs now and then. There is nothing wrong with you or your ability to learn. It is what it is, and that’s OK.
  • When you are talking with Brazilians who don’t have experience teaching Portuguese – and may not have experience learning another language – they may try to correct you too much. Don’t sweat it. I suggest creating an agreement with your friend: You will welcome feedback, but sometimes it’s much better to let the conversation flow without correcting small things that don’t compromise the meaning of what you’re saying.

Present Tense Conjugation of the Verb Ser in Portuguese

I will use the simple present tense in this lesson. Here’s the conjugation:

Eu sou

Você é

Ele/Ela é

Nós somos

Vocês são

Eles/Elas são

When to Use the Verb Ser

Allow me to oversimplify this for a moment and give you a rule of thumb: We usually use the verb Ser to describe characteristics that don’t change easily or often.

Let’s see 8 common situations in which we use the verb Ser in Portuguese.

1. Use Ser for introductions

  1. Eu sou Luciana. = I am Luciana.
  2. Meu nome é Luciana. = My name is Luciana.
  3. Este é Marcos. = This is Marcos.

2. Use Ser to express nationality or place of origin

  1. Eu sou brasileira. = I am Brazilian.
  2. Dani é do Brasil. = Dani is from Brazil.
  3. Eles são americanos. = They are Americans.

3. Use Ser to state your profession

  1. Eu sou professora. = I am a teacher.
  2. Márcio é médico. = Márcio is a physician.

Did you notice that we don’t use an article in front of the person’s profession? Learn all about articles in Portuguese, including differences in use between Portuguese and English.

In the beginning of the lesson I said that we use the verb Ser to describe characteristics that don’t change easily. I can change my profession, right? But this is not something I change from one moment to the next or according to my mood. This is the spirit of the verb Ser.

4. Use Ser to indicate marital status

  1. Joana é casada. = Joana is married.
  2. Nós somos solteiros. = We are single.
  3. Eles são divorciados. = They are divorced.

5. Use Ser to express relationships between people

  1. Elas são irmãs. = They are sisters.
  2. Vanessa e eu somos amigas. = Vanessa and I are friends.
  3. João é meu chefe. = João is my boss.

6. Use Ser to indicate ownership

  1. Este livro é meu. = This book is mine.
  2. Essa é a casa da Camila. = This is Camila’s house.

7. Use Ser to describe permanent or long-lasting characteristics of people, places, and objects

  1. Carol é muito engraçada. = Carol is very funny.
  2. Este livro é muito bom. = This book is very good.
  3. São Paulo é uma cidade fascinante. = São Paulo is a fascinating city.
  4. João é um cara alegre. = João is a joyful guy.

Notice that these examples describe how people, places, and things are in general, not how they are just now or how they feel at the moment (that is a job for the verb Estar).

8. Use Ser to express dates and time

  1. Hoje é quarta-feira. = Today is Wednesday.
  2. Hoje é dia 9 de novembro. = Today is November’s 9th.
  3. São onze horas. = It’s 11 am.

You may be thinking, “Wait! You just told me that I should use the verb Ser for permanent characteristics. It’s only 11 am for a minute.” I know, right? But we use the verb Ser for dates and for the time. Rules can help us, but they won’t answer all our questions.
