Informal Register | Portuguese (Brazil) Grammar

Informal register is not a degraded version of "real" Portuguese — in Brazil it is the real Portuguese that almost everyone speaks almost all the time. Among friends, family, classmates, coworkers of equal rank, and on social media, the informal register is the unmarked default; the formal register is the special-occasion outfit. For an English speaker this is a useful reframing: don't think of these features as "mistakes you're allowed to make," but as the native baseline you must produce to sound like a person rather than a textbook.

The informal register is a bundle of features that tend to travel together. You don't have to use all of them at once, but the more of them you use, the warmer and more casual you sound. Here is the bundle.

Address: você, cê, tu, a gente

The everyday address pronoun is você ("you"), which takes a third-person verb (você vai, você sabe). In fast speech it reduces to cê (cê viu?, cê quer?) — spoken only; never written except in dialogue or texting. In parts of the South, Northeast, and in Pará, people use tu instead, usually with a third-person verb in the colloquial style (tu vai).

For "we," informal BR overwhelmingly prefers a gente over nós. Crucially, a gente takes a third-person singular verb — a gente vai ("we go"), not a gente vamos.

Cê vai na festa do Léo hoje?

Are you going to Léo's party today?

A gente tá quase chegando, calma.

We're almost there, hold on.

Tu viu o que ele postou? Que vergonha.

Did you see what he posted? So embarrassing.

💡

A gente literally means "the people," yet it has become the everyday word for "we." It feels softer and more inclusive than nós, and it spares you the -mos conjugations. The one trap: agreement. It's a gente vai, a gente foi, a gente quer — third-person singular, always.

Proclisis: pronouns go first

Where formal writing attaches object pronouns to the end of the verb (dá-me, trata-se), spoken BR puts them in front — proclisis — and does so freely, even at the start of a sentence, which formal grammar technically forbids.

Me empresta dez reais? Te pago amanhã, juro.

Lend me ten reais? I'll pay you back tomorrow, I swear.

Se vira aí, eu já volto.

Manage on your own there, I'll be right back.

Starting a sentence with Me dá… or Te falei… is the natural spoken norm. A teacher might red-pen it in an essay, but no Brazilian would blink at it in conversation.

Reductions: the sound of casual speech

Informal speech compresses high-frequency words. These are spoken (and texting) forms — you hear and type them constantly, but you do not put them in formal writing.

Full form	Reduced (spoken)	English
está / estou	tá / tô	is / I am
para	pra	to / for
para o / para a	pro / pra	to the
você	cê	you
onde está?	cadê?	where is…?
não é?	né?	right? / isn't it?
está bom	tá bom / 'tá	okay / fine

Cadê o controle? Tava aqui agora há pouco.

Where's the remote? It was right here a minute ago.

Tô morrendo de fome, vamo comer alguma coisa, né?

I'm starving, let's go eat something, yeah?

Note vamo for vamos — dropping the final -s of nós forms is another casual feature.

Slang (gíria) and vocatives

Informal speech is full of gíria (slang) and casual vocatives used to address friends: mano, cara, véi/velho, bicho, parça, and in the Northeast visse / oxe. Evaluative slang is everywhere: massa / daora ("cool"), mó ("really, very"), zoar ("to mess around"), rolê ("an outing"), bagulho ("thing/stuff").

Mano, esse rolê tá daora demais!

Dude, this outing is so awesome!

Para de me zoar, cara, sério.

Stop teasing me, man, seriously.

💡

Slang dates fast and varies by region, age, and crowd. The vocatives cara and mano are the safest, most widespread choices; flashy slang you picked up from a meme can sound try-hard or out of date. Listen before you imitate.

Diminutives

The suffix -inho / -inha is a workhorse of informal BR, far beyond literal smallness. It softens requests, conveys affection, downplays, and adds warmth.

Me vê um cafezinho, por favor?

Could I get a (little) coffee, please?

Calma, é só um probleminha, a gente resolve rapidinho.

Relax, it's just a tiny problem, we'll sort it out quick.

Cafezinho isn't a small coffee — it's the friendly, default way to ask for a coffee. Rapidinho means "real quick." This affectionate diminutive use is much heavier in BR than the diminutive in English ("-ie/-y").

Discourse particles and null objects

Casual speech is structured by filler particles that organize the conversation: aí ("and then / so"), então ("so"), tipo ("like"), sei lá ("I dunno"), né ("right?"), olha ("look"). And BR speech freely drops the object when it's understood (the "null object"), where English needs "it":

Aí eu cheguei lá, tipo, e ele já tinha ido embora, sei lá.

So I got there, like, and he'd already left, I dunno.

— Cadê meu carregador? — Ah, peguei ∅ e deixei na sala.

— Where's my charger? — Oh, I grabbed it and left it in the living room.

Brazilians say peguei or vi ele far more often than the formal peguei-o / vi-o. The null object (vi ∅) and the "wrong" pronoun (vi ele) are both standard in speech; the enclitic vi-o sounds bookish out loud.

Relaxed agreement

In casual speech, plural marking often appears only once in the noun phrase: os menino, as casa amarela. This is widespread and socially patterned (more frequent in vernacular speech), but it is stigmatized in writing — recognize it, understand it, and keep full agreement when you write.

Os menino tudo já foram embora.

The kids have all already left. (vernacular spoken agreement)

When informal register is right — and when it misfires

Informal register is correct and expected with: friends, family, peers, children, on social media, in texting, in casual customer-service chat. It is warm, efficient, and native.

It misfires when the situation calls for distance or seriousness: a job-application email, a court, an academic paper, addressing an elder or a senior official you don't know, an official document. Saying cadê to a judge, cê in a cover letter, or a gente in a contract isn't a grammar error — it's a social miscalculation, the way wearing flip-flops to a funeral isn't illegal but is clearly wrong. The fix is to switch up: full forms, o senhor/a senhora, nós or the passive. See register/formal-register for the upward shift.

💡

The skill native speakers have and learners need is range — sounding casual with friends and buttoned-up with a notary. Mastering the informal register is half the job; knowing the moment to drop it is the other half.

Common Mistakes

❌ A gente vamos para a praia amanhã.

Incorrect — 'a gente' takes a third-person singular verb.

✅ A gente vai pra praia amanhã.

We're going to the beach tomorrow.

❌ Empresta-me dez reais aí?

Sounds bookish in casual speech — enclisis is too formal here.

✅ Me empresta dez reais aí?

Lend me ten bucks?

❌ Estou indo para o trabalho, você quer uma carona? (in a quick text to a friend)

Not wrong, but over-full for the medium — friends reduce.

✅ Tô indo pro trabalho, cê quer carona?

Heading to work, you want a ride?

❌ Vi-o ontem no shopping.

In speech this sounds stilted; spoken BR uses 'vi ele' or a null object.

✅ Vi ele ontem no shopping. / Vi ∅ ontem no shopping.

I saw him at the mall yesterday.

❌ Cadê o relatório, doutor? A gente precisa pra hoje.

Wrong register for addressing a superior — informal forms misfire.

✅ O senhor já tem o relatório? Precisamos dele para hoje.

Do you have the report yet, sir? We need it for today.

Key Takeaways

Informal register is the default of spoken BR, not a corrupted form.
Its core features cluster: você/cê, a gente (third-person singular!), proclisis (me dá), reductions (tá/tô/pra/cadê/né), slang, diminutives, fillers, null objects, relaxed agreement.
These are correct in speech and texting, stigmatized or wrong in formal writing.
The real competence is range — switching off informal features the instant the context turns formal.
