Present Indicative of Ser | Portuguese (Brazil) Grammar

Portuguese splits the English verb to be into two verbs: ser and estar. Ser is the verb of identity and essence — what something fundamentally is: who you are, where you're from, your profession, the time, who owns what. It is one of the most irregular verbs in the language and also one of the most frequent, so it pays to learn it cold from day one.

Conjugation

Ser is irregular: you cannot derive its forms from a stem, so memorize them as a set.

Subject	Conjugation
eu	sou
tu (regional / literary)	és
você / ele / ela	é
nós	somos
vocês / eles / elas	são

💡

The standard tu form is és, which you'll meet in literature, song lyrics, and parts of the South and Northeast. But in most of Brazil's casual speech where tu survives, people simply say "tu é" — borrowing the você form. This is non-standard but widespread; for your own production, stick with você é, which is universally correct in Brazil.

Note the diacritics: é (the verb) carries an acute accent. Without it, e is just the word for "and." So ela e médica means "she and a doctor" (a fragment), while ela é médica means "she is a doctor." The accent is doing real work — never drop it.

Eu sou brasileiro, nasci em Salvador.

I'm Brazilian; I was born in Salvador.

Nós somos amigos desde a escola.

We've been friends since school.

Core uses of ser

Identity and profession

Use ser to say who or what someone is — names, roles, professions, relationships.

Ela é médica e trabalha num hospital público.

She's a doctor and works at a public hospital.

Esse é o Pedro, meu primo.

This is Pedro, my cousin.

Portuguese drops the article before professions: ela é médica, not "ela é uma médica." Adding uma there sounds like English interference.

Origin and nationality

Use ser de to express where someone or something is from.

Somos do Rio, mas moramos em São Paulo.

We're from Rio, but we live in São Paulo.

Esse queijo é de Minas, o melhor que tem.

This cheese is from Minas Gerais, the best there is.

Time and dates

Telling the time and giving the date both use ser. Note that the verb agrees with the number of hours, so it's usually plural.

São três horas da tarde.

It's three in the afternoon.

Hoje é segunda-feira, dia vinte.

Today is Monday, the twentieth.

One o'clock is singular: é uma hora. Everything from two on is plural: são duas horas, são dez horas.

Possession

To say something belongs to someone, use ser de (or ser + possessive).

Esse livro é meu, não é seu.

This book is mine, not yours.

O carro é do meu pai, eu só peguei emprestado.

The car is my dad's; I just borrowed it.

Defining and lasting traits

Use ser for characteristics treated as part of who or what something is — height, color, personality, material.

Ela é alta e tem cabelo cacheado.

She's tall and has curly hair.

A mesa é de madeira maciça.

The table is (made of) solid wood.

This is the boundary with estar: ser describes the defining trait, estar describes a passing state. Ela é alegre (she's a cheerful person) versus ela está alegre (she's feeling happy right now). See choosing between ser and estar for the full decision guide.

The big insight: ser for the location of events

Here is the rule that trips up nearly every English speaker — and even confuses Spanish speakers who think they've got it. When you say where an event takes place, you use ser, not estar. An event (a party, a meeting, a concert) doesn't sit in a place the way an object does; it happens there, so Portuguese treats it like identity.

A festa é na minha casa, chega lá pelas oito.

The party is at my place; show up around eight.

A reunião é na sala três, no segundo andar.

The meeting is in room three, on the second floor.

O show é no estádio, mas o ensaio é aqui.

The concert is at the stadium, but the rehearsal is here.

Contrast this sharply with the location of a thing or person, which always takes estar (or ficar):

A comida está na geladeira.

The food is in the fridge.

So: the party (event) é na minha casa, but the food (object) está na geladeira. Ask yourself "does it happen somewhere or does it sit somewhere?" Events happen — ser. Things sit — estar.

💡

A quick test: if you could rephrase with "takes place" in English, use ser. "The wedding takes place at the church" → O casamento é na igreja. You'd never say "the keys take place on the table," so keys get estar.

Common mistakes

❌ Eu estou brasileiro.

Incorrect — nationality is an identity, so it takes ser, not estar.

✅ Eu sou brasileiro.

I'm Brazilian.

❌ A festa está na minha casa.

Incorrect — the location of an event takes ser.

✅ A festa é na minha casa.

The party is at my place.

❌ Ela é uma médica.

Incorrect — Portuguese drops the article before a profession.

✅ Ela é médica.

She's a doctor.

❌ É uma hora? Não, é três horas.

Incorrect — from two o'clock on, the verb is plural.

✅ São três horas.

It's three o'clock.

❌ Ela e a melhor da turma.

Incorrect — without the accent, 'é' becomes 'e' (and), which breaks the sentence.

✅ Ela é a melhor da turma.

She's the best in the class.

Key takeaways

Ser = sou, és, é, somos, são — irregular, frequent, learn it whole.
Use it for identity, profession, origin, time, possession, and defining traits.
The classic stumbling block: the location of an event takes ser (a festa é aqui), while the location of a thing takes estar (o livro está aqui).
Mind the accent on é — it distinguishes the verb from the conjunction e ("and").
