Conjugation Basics

To conjugate a verb is to reshape it so it carries information about who is doing the action, how many of them, when it happens, and in what mood. English does almost none of this — we add "-s" for he/she and that is nearly the whole story ("I walk / you walk / we walk / they walk", only "he walks" changes). Brazilian Portuguese, by contrast, packs all four pieces of information into the ending of the verb. Once you see how the parts fit together, the system stops looking like memorization and starts looking like a small machine.

The anatomy of a conjugated verb

A Brazilian Portuguese verb form is built from up to four slots, read left to right:

radical (stem) + vogal temática (theme vowel) + marca de tempo/modo (tense/mood marker) + desinência (person/number ending)

Let's take falar (to speak) and build the form falávamos ("we were speaking," imperfect indicative):

SlotPieceCarries
radicalfal-the lexical meaning "speak"
theme vowel-á-marks it as an -ar (1st class) verb
tense/mood-va-marks imperfect indicative
person/number-mosmarks "we" (1st person plural)

Stack them: fal- + -á- + -va- + -mosfalávamos. Every conjugated form in the language is assembled this way, even when the slots fuse together so tightly you can no longer see the seams.

A gente caminhava na praia toda manhã naquele verão.

We used to walk on the beach every morning that summer.

You do not need to consciously break verbs into four pieces to speak. But understanding the architecture explains why the endings look the way they do, and it makes the patterns across tenses feel connected rather than arbitrary.

💡
The theme vowel is the single most useful diagnostic in the system. The -a- in falávamos tells you instantly it's an -ar verb; an -e- or -i- would point to the other two classes. Learn to spot the theme vowel and half the work of identifying a verb's class is done.

What the endings tell you

Because so much information lives in the ending, a bare verb form is often a complete, unambiguous sentence. The ending alone tells the listener who the subject is.

FormMeansWhy
faloI speak-o ending = eu
falamoswe speak-mos ending = nós
falamthey / you all speak-m ending = 3rd plural

Falo três línguas.

I speak three languages.

Moramos no mesmo prédio.

We live in the same building.

The six slots — and why daily speech uses fewer

Standard grammar gives six person-number combinations. Here is falar in the present indicative across all of them, with the everyday reality noted alongside:

SlotPronounFormEveryday Brazilian reality
1sgeufaloused everywhere
2sgtufalasregional; most of Brazil says você instead
3sgele / ela / vocêfalaused everywhere; also covers "you" (você)
1plnósfalamosused, but spoken Brazil often prefers a gente fala
2plvósfalaisdead in Brazil — never used (archaic)
3pleles / elas / vocêsfalamused everywhere; also covers plural "you" (vocês)

Strip out the dead vós form and the regional tu form, fold nós into a gente, and most speakers operate with four to five distinct forms per tense, not six. This is the practical paradigm to internalize first:

SubjectForm
eufalo
você / ele / ela / a gentefala
nósfalamos
vocês / eles / elasfalam

A gente trabalha junto há cinco anos.

We've been working together for five years.

Eles chegam amanhã de manhã.

They arrive tomorrow morning.

For the full story on a gente — why a word meaning "we" takes a singular verb — see the a gente page.

Why subject pronouns are usually dropped

Because the ending already encodes the subject, the subject pronoun is frequently redundant, and Brazilians drop it. Saying eu before falo is a little like saying "I, I speak" — the -o already told you it was "I."

Moro em Salvador, mas trabalho em Lauro de Freitas.

I live in Salvador, but I work in Lauro de Freitas.

Notice there is no eu anywhere in that sentence — the -o endings carry it twice. Including eu is not wrong; it just adds emphasis or contrast.

Eu pago a conta, você deixa a gorjeta.

I'll pay the bill, you leave the tip.

Here both pronouns appear precisely because the speaker is contrasting two subjects. Pronouns resurface when you need to highlight who is who.

This is a real adjustment for English speakers. English requires the subject ("speak" alone is not a sentence; "I speak" is). In Brazilian Portuguese, leaving the pronoun in every clause sounds heavy and slightly foreign.

💡
Drop the subject pronoun by default. Put it back only for emphasis, contrast, or — crucially — to disambiguate ele / ela / você, which all share the same verb form. That's the one place the ending genuinely can't tell you who's meant.

The exception: ele, ela, and você collide

There is one slot where the ending does not settle the subject. Ele (he), ela (she), and você (you) all take the identical 3sg form. So fala on its own could mean "he speaks," "she speaks," or "you speak." When context doesn't make it obvious, you keep the pronoun.

Ela fala muito bem, mas ele fica nervoso na frente das pessoas.

She speaks very well, but he gets nervous in front of people.

Você fala inglês ou prefere que eu fale português?

Do you speak English, or would you rather I speak Portuguese?

In both, removing the pronoun would leave the listener guessing. This is the mirror image of the general rule: usually you drop pronouns because the ending is informative; here you keep them because the ending is ambiguous. The subject pronouns page covers exactly when each pronoun is required.

Common mistakes

❌ Eu eu trabalho muito. / Eu trabalho, eu estudo, eu cozinho todo dia.

Incorrect/heavy — repeating 'eu' in every clause sounds foreign; drop it.

✅ Trabalho, estudo e cozinho todo dia.

I work, study, and cook every day.

❌ A gente falamos sobre isso ontem.

Incorrect — 'a gente' takes the 3sg form 'fala', never the nós form 'falamos'.

✅ A gente falou sobre isso ontem.

We talked about that yesterday.

❌ Fala português? (meaning 'do you speak Portuguese?', with no context)

Risky — without 'você', the listener can't tell if you mean he/she/you.

✅ Você fala português?

Do you speak Portuguese?

❌ Nós falais demais.

Incorrect — 'falais' is the dead vós form; it's archaic and never used in Brazil.

✅ Nós falamos demais.

We talk too much.

Key takeaways

  • Conjugation = stem + theme vowel + tense/mood marker + person/number ending. The theme vowel reveals the class.
  • The ending encodes the subject, so subject pronouns are usually dropped.
  • Six textbook slots collapse to four or five in real Brazilian speech: vós is dead, tu is regional, a gente (3sg) competes with nós.
  • Keep the pronoun for emphasis, for contrast, and especially to separate ele / ela / você, which all share one form.
