In Brief

Portuguese has two common verbs corresponding to English “to be.” Use ser for identity, origin, profession, defining characteristics, and clock time: Sou médico, Ela é de Lisboa, São três horas. Its present-tense forms are irregular: sou, és, é, somos, sois, são.

Overview

Ser is one of the most important Portuguese verbs. It identifies or classifies someone or something: who a person is, where something comes from, what kind of thing it is, or what characteristic defines it in the current conversation. You also use it to tell the time. These are A1 essentials, so learning the six forms as a complete set pays off immediately.

English uses one verb in sentences such as “I am Brazilian,” “I am tired,” and “I am at home.” Portuguese normally divides those meanings between ser and estar. At first, think of ser as answering questions like “Who or what is it?”, “What is it like?”, and “Where is it from?” Use estar for states and locations: Estou cansado (“I am tired”) and Estou em casa (“I am at home”).

The familiar shortcut “ser is permanent; estar is temporary” can help occasionally, but it is not the real rule. A temporary profession can still take ser, while a permanent location normally takes estar. Learn the typical uses rather than trying to judge how long a situation lasts.

How It Works

Ser is an irregular verb: its forms do not follow one predictable set of endings. A subject is the person or thing that the sentence is about. Match the form of ser to that subject.

Person	Subject pronoun	Present form	English equivalent
First-person singular	eu	sou	I am
Second-person singular	tu	és	you are
Third-person singular	ele, ela, você	é	he/she is; you are
First-person plural	nós	somos	we are
Second-person plural	vós	sois	you are
Third-person plural	eles, elas, vocês	são	they are; you are

The accent marks matter: é means “is,” while e means “and”; és means “you are.” São has a nasal vowel and must not be confused with sou.

Portuguese often leaves out a subject pronoun when the context and verb form make the subject clear: Sou portuguesa naturally means “I am Portuguese.” However, é and são can refer to several possible subjects, so a noun or pronoun is often useful: Ela é professora; Vocês são estudantes.

Choosing the form of “you”

The grammar and everyday choice of “you” vary across the Portuguese-speaking world.

Subject	Form of ser	Typical use
tu	és	Common informal singular in Portugal and in parts of Brazil
você	é	Very common singular address in Brazil; also used in Portugal, with different social nuances
vocês	são	Normal plural “you” in Brazil and widely used in Portugal
vós	sois	Rare in ordinary modern conversation; found in religious, literary, ceremonial, and some regional language

For a reliable beginner sentence, keep the subject and verb together as a pair: tu és, você é, vocês são. In Brazil, regional speech sometimes combines tu with a third-person verb, but tu és is the standard grammatical pairing and the best form to learn first.

Main uses of ser

Identity and classification

Use ser to say who someone is or what something is:

• Eu sou a Marta. — “I am Marta.”
• Isto é um dicionário. — “This is a dictionary.”
• Eles são os meus vizinhos. — “They are my neighbors.”

A noun is a word naming a person, place, thing, or idea. When a profession or role is given as a noun after ser, Portuguese normally uses no indefinite article where English uses “a/an”:

• Ela é engenheira. — “She is an engineer.”
• Somos estudantes. — “We are students.”

An article can appear when the profession is modified or specifically identified: Ela é uma engenheira excelente (“She is an excellent engineer”) and Ela é a engenheira responsável pelo projeto (“She is the engineer responsible for the project”).

Origin, nationality, and material

Use ser de for origin:

• Sou de Portugal. — “I am from Portugal.”
• O café é do Brasil. — “The coffee is from Brazil.”

Use ser with nationality and similar descriptions: Ele é português; Elas são brasileiras. An adjective is a describing word. Portuguese adjectives often change to agree with the gender and number of the person or thing described: português, portuguesa, portugueses, portuguesas.

Ser de can also express material or, depending on context, possession:

• A mesa é de madeira. — “The table is made of wood.”
• Este casaco é da Ana. — “This coat is Ana’s.”

Here do and da are contractions: de + o = do and de + a = da.

Characteristics

Use ser for a characteristic presented as part of someone’s or something’s identity or nature:

• Ela é alta e bonita. — “She is tall and beautiful.”
• A cidade é tranquila. — “The city is peaceful.”
• Este exercício é difícil. — “This exercise is difficult.”

This does not claim that the characteristic can never change. It presents the description as characteristic or generally true in the context.

Time, dates, and general facts

Use é with one o’clock and são with plural hours:

• É uma hora. — “It is one o’clock.”
• São duas horas. — “It is two o’clock.”
• Que horas são? — “What time is it?”

For dates and days, common patterns include Hoje é sábado (“Today is Saturday”) and Hoje é dia dez (“Today is the tenth”). Portuguese also uses ser for definitions and general statements: Lisboa é a capital de Portugal.

The beginner contrast: ser or estar?

Meaning	Use	Example
identity or category	ser	A Joana é médica. — Joana is a doctor.
origin	ser	Somos de Angola. — We are from Angola.
characteristic	ser	O quarto é pequeno. — The room is small.
current state	estar	A Joana está cansada. — Joana is tired.
location of a person or object	estar	O livro está na mesa. — The book is on the table.

Ask what you mean, not whether it is “permanent.” Ele é estudante este mês still classifies him as a student, despite the short period. Lisboa está em Portugal uses estar for geographical location, despite that location being stable.

O Rui é engenheiro.	Rui is an engineer.	No article before an unmodified profession
Nós somos estudantes.	We are students.	First-person plural
Vocês são de Moçambique?	Are you from Mozambique?	Plural “you” plus origin
Eles são os meus vizinhos.	They are my neighbors.	Identification with a definite noun phrase

Common Mistakes

Using the infinitive instead of a conjugated form

• Wrong: Eu ser estudante.
• Right: Eu sou estudante.
• Why: Ser is the infinitive (the dictionary form, like English “to be”). A present-tense statement needs the form that matches the subject.

Making você agree like tu

• Wrong: Você és brasileiro?
• Right: Você é brasileiro?
• Why: Although você means “you,” it takes a third-person verb form. Use tu és but você é.

Adding an article before every profession

• Less natural for a neutral statement: Ela é uma médica.
• Usual: Ela é médica.
• Why: Portuguese generally omits um/uma before an unmodified profession, religion, or nationality used as a classification. Add the article when there is a modifier: Ela é uma médica excelente.

Using é for every clock time

• Wrong: É três horas.
• Right: São três horas.
• Why: Use singular é with uma hora and plural são with two or more hours.

Choosing ser only because something seems permanent

• Wrong: A farmácia é na esquina. (when you mean the building’s location)
• Right: A farmácia está na esquina.
• Why: The location of a person, object, or place normally uses estar, even when it is stable. Event location is an important exception discussed below.

Forgetting adjective agreement

• Wrong: Elas são português.
• Right: Elas são portuguesas.
• Why: A descriptive adjective normally agrees with the people described in gender and number.

Usage Notes

In natural speech, eu and nós can be omitted when sou and somos clearly identify the subject. Speakers may keep the pronoun for contrast: Eu sou de Braga, mas ela é do Porto (“I’m from Braga, but she’s from Porto”). Brazilian Portuguese tends to state subject pronouns more often than European Portuguese, but omission remains possible.

In everyday Brazilian Portuguese, a gente commonly means “we” but takes a singular verb: A gente é do Brasil (“We are from Brazil”). As a learner, remember the contrasting verb pairings a gente é and nós somos. Use nós somos in formal writing and whenever you want a neutral standard form.

Pronunciation varies considerably between Brazil, Portugal, and other Portuguese-speaking regions. The written forms remain the same. Learn the accent and address system most relevant to you, while recognizing both tu és and você é.

Beyond the Basics / Advanced Use

You do not need to master all of these points at A1, but they prevent the beginner rule from becoming misleading later.

The choice can change the meaning

Some adjectives work with both verbs, but the speaker’s perspective changes:

• Ele é calmo. — He is a calm person.
• Ele está calmo. — He is calm now.
• A sopa é boa. — The soup is good (a judgment about it).
• A sopa está boa. — The soup tastes good / has turned out well now.

This is more useful than the “permanent versus temporary” shortcut: ser characterizes; estar presents a state or condition.

Events use ser for location and time

People and physical objects are located with estar, but an event is commonly located with ser:

• A reunião é no segundo andar. — “The meeting is on the second floor.”
• O concerto é amanhã. — “The concert is tomorrow.”

Compare Os músicos estão no teatro (“The musicians are at the theater”), where the subject is people, not the event.

Ser in the passive voice

At a later level, you will meet ser + past participle in the passive voice, a structure that focuses on what receives an action. A past participle is a verb form such as feito (“done/made”) or escrito (“written”):

• O pão é feito aqui. — “The bread is made here.”
• As cartas são enviadas de manhã. — “The letters are sent in the morning.”

The participle agrees with the subject: feito, feita, feitos, feitas. This is a separate construction from simply describing identity, but it uses the same present forms of ser.

Impersonal é

Portuguese frequently uses é in evaluations and fixed patterns: É importante estudar (“It is important to study”), É possível pagar com cartão? (“Is it possible to pay by card?”). Here there is no ordinary person or object as the subject; é introduces a general judgment.

Practice Tips

1. Learn forms in useful pairs. Say eu sou, tu és, você é, nós somos, vocês são. Then replace pronouns with names or nouns: A Ana é, os alunos são.
2. Sort examples by meaning. Make five headings—identity, origin, profession, characteristic, and time—and write two true sentences under each. This builds usage, not just memorization.
3. Contrast ser and estar aloud. Describe one person with a characteristic and a current state: Ela é alegre, mas hoje está cansada. This trains the difference without relying on “permanent versus temporary.”
