Ser or estar? Naming against describing

The shorthand, and why it will let you down

Almost every course opens with permanent against temporary, and it is a fair place to start:

• Ele é o pai dela. - He is her father. (that does not change)
• Eu estou em casa. - I am at home. (I will not be later)

Use that rule and you are right most of the time in your first month. Then it leaks, in both directions:

So the shorthand is scaffolding, not the building.

The line that actually holds

Ask which of these two you are doing:

1. Naming what something IS: its identity, origin, job, what kind of thing it is. That is ser: Ela é professora., she is a teacher.
2. Describing the condition it is IN: where it is now, how it stands, what has happened to it. That is estar: Ela está cansada., she is tired.

1. 1Ela é médica.
2. 2Ele é professor.
3. 3Ele é cozinheiro.
4. 4Ele é policial.

What each of them is: a job names the person, so ser, however long they keep it. (EP says polícia for a police officer.)

Read that way, the awkward cases stop being awkward. Death is a state a person has ended up in, not a category of person, so estar. A price is presented as a fact about the thing, so ser. The line is not about how long something lasts; it is about classifying against describing.

How to get it right without thinking

Three habits cover most of what you will say in your first months:

1. Where a person or a movable thing is: estar. Ele está aqui., he is here.
2. Where a building or a city is: ficar is the usual Brazilian choice. Onde fica o museu?, where is the museum?
3. Identity: ser. Names, nationalities, jobs, family: Ela é minha irmã., she is my sister.

If you know Spanish, the Spanish ser and estar maps onto this closely, but where Spanish says a building está somewhere, Portuguese says fica. Both verbs are in the first chapter of the Portuguese course, which is where to make them automatic.
