Uses of Estar
If ser is the verb of identity, estar is the verb of the moment. Where ser answers “what are you?”, estar answers “how are you - right now?” It’s the verb you reach for when something could be different tomorrow, when you’re describing a state someone is in rather than something they fundamentally are.
And before you reach for the permanent vs. temporary rule - don’t. As we saw with ser, that shortcut breaks down fast. Ele está morto uses estar, and death is about as permanent as it gets. The better frame is this: estar is about condition and position - where something is, and what state it’s currently in.
Let’s go through the main uses.
Physical States
When someone’s body is in a particular condition - sick, tired, hurt, well - that’s estar.
Eu tô doente.
I am sick.
Ela tá cansada.
She is tired.
A gente tá bem, só sem dinheiro mesmo.
We are fine, just with no money at all.
Eu tô gripado.
I am sick with the flu.
Eles tão com covid-19.
They have COVID-19.
Nós tamo cansado demais pra nadar de novo.
We are too tired to swim again.
Ele tá com câncer.
He has cancer.
This is also where the permanent/temporary rule misleads people the most. Sickness feels temporary, so beginners get this one right for the wrong reason. The real logic is that being sick is a state you’re in, not part of your identity - and that’s what estar marks.
Mental and Emotional States
Feelings and moods work the same way. They’re conditions, not definitions.
Você tá feliz.
You are happy.
Você tá louca, mulher?
Are you crazy, woman?
Ele tá triste porque a mulher dele foi embora.
He is sad because his wife left.
A gente tá zangado com vocês!
We are mad at you guys!
Eu tô com nojo disso.
I am disgusted by this.
Ele tá apaixonado por ela.
He is in love with her.
Nós estamos animados pra festa amanhã.
We are excited for the party tomorrow.
Eles tão frustrados com o novo filme.
They are frustrated with the new movie.
Someone isn’t defined by being happy right now - they’re experiencing happiness. Hence estar. This is also why ser feliz and estar feliz can both exist in Portuguese with slightly different shades: ser feliz is more “to be a happy person by nature”, estar feliz is “to be feeling happy at this moment.”
Point of Location
Where something physically is - its position in space - uses estar.
Ele tá em casa.
He is at home.
Eu tô no supermercado.
I am at the supermarket.
Ele tá na Europa.
He is in Europe.
Nós estamos em Paris.
We are in Paris.
Admite Maria, a gente tá perdido.
Admit it Maria, we are lost.
Eles tão em São Paulo agora.
They are in São Paulo now.
This is one of the clearest rules in the whole ser/estar divide. People, objects, and animals use estar for location. The one exception worth knowing is events - A festa é no meu apartamento uses ser, because the location is being treated as a defining fact about the event, not a position in space. But for everything else: location is estar.
Present Progressive
When you want to say someone is in the middle of doing something - the equivalent of English’s “-ing” form - Portuguese builds it with estar + the gerund.
Ela tá trabalhando.
She is working.
Nós estamos comprando comida.
We are buying food.
Eles tão viajando agora.
They are traveling right now.
Eu tô chorando porque meu cachorro morreu.
I am crying because my dog died.
Ela tá no quarto ouvindo música.
She is in her room listening to music.
A gente tá reformando nossa casa.
We are renovating our house.
Ele tá aprendendo a tocar violão.
He is learning to play the guitar.
Eu tô morrendo, meu filho!
I am dying, my son!
This one is straightforward and consistent. Whatever the action, if it’s happening right now and you want to emphasize that it’s ongoing, estar is your verb.
Four uses, one underlying idea: estar is about where you are and how you are - in space, in your body, in your head, in the middle of an action. None of those are fixed. All of them can change. And that’s exactly the kind of thing estar is built to express.
Taken together with ser, you now have the full picture of to be in Portuguese. The line between them isn’t always clean - there are edge cases, regional preferences, and constructions that will make you pause even at an advanced level. But the core logic holds: define with ser, describe with estar. Start there, and the rest will fall into place.
