Portuguese has two verbs for “to be,” and English has one. That single fact trips up more beginners than any other point of grammar. Ser and estar both translate to “am, is, are,” so the question is never what they mean. It is which one the sentence needs.
Ser is the verb of identity. It answers who someone is and where they come from. It also covers what they do for a living. These are the facts that stay put.
O meu nome é Ana.
My name is Ana.
identity
Ela é brasileira.
She is Brazilian.
nationality
Ele é do Brasil.
He is from Brazil.
origin
Nós somos dos Estados Unidos.
We are from the United States.
origin
A Ana é professora.
Ana is a teacher.
profession
A profession counts as identity in Portuguese, so it takes ser, even though a job can change over a lifetime. A Ana é professora says what Ana is, not how she feels today.
Estar is the verb of the moment. It covers how you feel, how you are doing, where something is right now, and what is going on as you speak.
Eu estou bem, obrigado.
I am well, thank you.
Eu estou cansado.
I am tired.
Eu não estou cansado, eu estou feliz.
I am not tired, I am happy.
A minha mãe está bem.
My mother is well.
A Ana está doente.
Ana is sick.
Estar also places things and people. It answers where something is at this moment.
O supermercado está ali.
The supermarket is over there.
A Ana está na escola.
Ana is at school.
Paired with a verb in the -ndo form, estar describes what is happening as you speak.
Ela está lendo um livro.
She is reading a book.
Here is the same split across the situations you meet first.
| Situation | Verb | Example |
|---|---|---|
| Name and identity | ser | O meu nome é Ana. |
| Origin and nationality | ser | Ela é brasileira. |
| Profession | ser | A Ana é professora. |
| Feelings and mood | estar | Eu estou feliz. |
| Health | estar | A minha mãe está bem. |
| Location right now | estar | O supermercado está ali. |
| What is happening now | estar | Ela está lendo um livro. |
The clearest way to feel the difference is to watch one person take both verbs in the same breath.
A Ana é médica, mas hoje ela está doente.
Ana is a doctor, but today she is sick.
What Ana is (a doctor) does not change, so that half takes ser. How Ana is (sick) is a state that passes, so that half takes estar. Swap the verbs and a Brazilian hears a different, wrong meaning. A Ana está médica sounds like being a doctor is a passing mood.
Both verbs are irregular, so the forms are worth memorizing as a set. These are the present-tense forms you use every day.
| Pronoun | Ser |
|---|---|
| eu | sou |
| você / ele / ela | é |
| nós | somos |
| a gente | é |
| vocês / eles / elas | são |
| Pronoun | Estar |
|---|---|
| eu | estou |
| você / ele / ela | está |
| nós | estamos |
| a gente | está |
| vocês / eles / elas | estão |
A gente means “we” in everyday Brazilian speech and takes the same form as “ele / ela,” so a gente está sits right next to nós estamos. Brazilians use both.
In fast conversation, está compresses further, to tá, and estou to tô. Our guide to spoken Portuguese contractions covers the full set.
These are the slips that come straight from having one verb in English. Each one is a real correction from the classroom.
Eu sou cansado.
Eu estou cansado.
Tiredness is a state, so it takes estar. Eu sou cansado would describe tiredness as part of who you are.
A Ana está professora.
A Ana é professora.
A profession is identity in Portuguese, so it takes ser, not estar.
Ela é cansada.
Ela está cansada.
The same trap in reverse. A mood or condition uses estar, never ser.
Eu está bem.
Eu estou bem.
Watch the person too. The eu form of estar is estou, not está.
Nós está cansados.
Nós estamos cansados.
The nós form is estamos, and the adjective goes plural: cansados.
Keep these four in your pocket and most sentences sort themselves.
Ser
Identity and lasting traits: name, origin, nationality, profession.
Estar
Current state: feelings, health, location, what is happening now.
Profissão
A profession takes ser, and a mood takes estar, even when both feel temporary in English.
Teste rápido
If 'for the moment' fits the English, use estar.
Ser and estar are grammar you can drill on paper. Catching them in a real conversation at full speed is a different skill; if that is still the gap, see our guide on what to do after Duolingo.
