◆ GRAMMAR
19 min read · Updated August 7, 2026
Portuguese has a future tense you can conjugate: falarei, falará, falaremos, falarão. Then you spend a week listening to Brazilians and almost none of it turns up. What you hear instead is vou, vai, vamos and vão, each one followed by a verb in its dictionary form. Same future. Different machinery, and you own most of it already.
Portuguese has two ways to point at tomorrow, and neither one is wrong. The conjugated future puts the ending on the verb itself: falarei. The spoken future puts ir in front and leaves the verb alone: vou falar. What separates them is register, so the question is never which one is correct. It is which one fits the room you are in.
| What you want to say | In conversation | In writing or formal speech |
|---|---|---|
| I'll talk to him tomorrow | Amanhã eu vou falar com ele. | Amanhã falarei com ele. |
| We'll travel in July | A gente vai viajar em julho. | Viajaremos em julho. |
| It's going to rain | Vai chover. | Choverá. |
| They'll get here late | Eles vão chegar tarde. | Chegarão tarde. |
Say the middle column at a Brazilian dinner table and you sound like everyone else there. Say the right column and you sound like a written sentence read out loud, which is the right effect in a speech and an odd one over a plate of rice and beans. It is unlikely that anyone corrects you for it. What they hear is the formality you did not intend.
The good news is arithmetic. You already conjugate ir, you already know the infinitive of every verb you have learned, and those two facts together give you the entire spoken future. There is no third thing to memorize before you can make a plan out loud.
Four forms of ir carry it. The verb after them never changes shape, which is the detail that saves you and the detail learners drop first.
| Person | Ir | The future |
|---|---|---|
| eu | vou | eu vou falar |
| você / ele / ela | vai | ela vai chegar |
| a gente | vai | a gente vai sair |
| nós | vamos | nós vamos viajar |
| vocês / eles / elas | vão | eles vão trabalhar |
Eu vou te ligar amanhã.
I'll call you tomorrow.
Ela vai chegar às oito.
She'll get here at eight.
A gente vai sair hoje à noite.
We're going out tonight.
Vocês vão gostar daqui.
You're going to like it here.
Eu não vou trabalhar na segunda.
I'm not working on Monday.
negation sits in front of vou, and nowhere else
Você vai comer alguma coisa?
Are you going to eat something?
no helper verb for questions, the intonation does it
Vai dar certo.
It'll work out.
no subject needed, and you will hear this one a lot
Não vai dar tempo.
There won't be time.
One more piece of good news hides in the table. English splits “I will call you” from “I am going to call you,” and picks between them by how planned the thing feels. Portuguese covers both with the same shape. Eu vou te ligar carries the promise and the plan in one move.
A gente means “we” and takes the singular verb, so the future is a gente vai viajar. Our own material flags a gente vão as the error to expect, and it is the most common one in the whole pattern. Nós vamos viajar is the other correct version of that same sentence. Our guide to a gente vs nós covers the pronoun in full.
A gente vai fazer um churrasco no sábado.
We're doing a barbecue on Saturday.
Nós vamos chegar juntos.
We'll get there together.
Brazilians rarely leave the future to the verb alone. A time word opens the sentence and does half the work, and these are the ones that come around every day.
| Time word | English | In a sentence |
|---|---|---|
| hoje à noite | tonight | Hoje à noite eu vou cozinhar. |
| amanhã | tomorrow | Amanhã eu vou trabalhar em casa. |
| depois de amanhã | the day after tomorrow | Depois de amanhã a gente vai viajar. |
| semana que vem | next week | Semana que vem eu vou mudar de apartamento. |
| mês que vem | next month | Mês que vem eles vão abrir a loja. |
| ano que vem | next year | Ano que vem eu vou morar no Brasil. |
| no fim de semana | on the weekend | No fim de semana eu vou à praia. |
| mais tarde | later | Mais tarde a gente vai comer alguma coisa. |
| daqui a pouco | in a little while | Daqui a pouco eu vou sair. |
| já já | in a minute | Já já eu te ligo. |
| um dia desses | one of these days | Um dia desses eu vou aprender a cozinhar. |
Two of those repay a closer look. Já já is the doubled já, and doubling it moves the meaning from “now” to “in a moment, very soon.” It is the answer a waiter gives you when the food is on its way. Daqui a pouco is the looser cousin, a little while from now, with the exact size left comfortably vague.
Writing prefers na semana que vem and no ano que vem with the preposition in front. Speech drops it and starts the sentence on semana que vem. Both reach the same place, so use whichever comes out, and expect the shorter one when you listen.
Plenty of the vou sentences you say will have no second verb at all. They will have a destination, and the little word in front of it is where a fluent-sounding sentence gets made or lost.
Portuguese uses two prepositions for going places, a and para, and each one fuses with the article in front of the noun. That fusion is compulsory. Our course material drills it as the heart of the lesson and lists eu vou a o cinema as the error to expect.
| Written | What it is | Example |
|---|---|---|
| ao | a + o, masculine | Eu vou ao cinema no fim de semana. |
| à | a + a, with the crase accent | Eu vou à praia no sábado. |
| para o | spoken as pro | Eu vou pro trabalho de manhã. |
| para a | spoken as pra | Eu vou pra casa da minha irmã. |
The gender of the place decides the contraction, not the sound of the word. Praia is feminine, so it takes à, and eu vou ao praia is the slip our material anticipates. Cinema is masculine despite the final a, so it takes ao.
On para: the book form is para o and para a, and the mouth form is pro and pra. That is exactly how our teachers model it, saying the short one and writing the full one. Write para and expect pra when you listen.
One honest note on a form you will hear constantly: eu vou na praia is everywhere in relaxed speech, built on em instead of a. It is not the form careful writing uses, so keep à praia when you write, and recognize the other one when it comes at you across a table.
Eu vou ao médico amanhã de manhã.
I'm going to the doctor tomorrow morning.
A gente vai à festa da Ana.
We're going to Ana's party.
Eu vou pro mercado, quer alguma coisa?
I'm off to the market, do you want anything?
Ele vai pra academia todo dia.
He goes to the gym every day.
here vai is habit, not future
Sooner or later you need “I am going to go,” and the pattern hands you ir twice. This is the point where learners freeze, so here is the plain answer.
You will hear vou ir in Brazil. It comes out of relaxed speech and nobody blinks at it. It also gets flagged as a repetition in careful speech and in writing, which is why many Brazilians avoid it once they are paying attention to how they sound. Since opinions on it split, there is no reason to plant your flag on that hill.
Eu vou amanhã.
I'll go tomorrow.
A gente vai de carro.
We'll go by car.
Eu vou ao show com o Pedro.
I'll go to the show with Pedro.
Você vai à reunião? Vou.
Are you going to the meeting? I am.
the one-word answer repeats the verb, and it is how Brazilians say yes
That last line is worth practising on its own. Portuguese prefers to answer a yes-or-no question by echoing the verb, and sim rides along behind it instead of standing on its own. Você vai? gets vou or vou sim, and não vou in the other direction.
English uses one shape for two jobs. “I am going to the beach” can mean tomorrow, and it can mean I am in the car right now. Portuguese keeps those apart, and mixing them is the error that survives longest.
| Shape | What it means | Example |
|---|---|---|
| vou + infinitivo | a plan or a prediction | Eu vou almoçar com ela. |
| estou / tô + gerúndio | what is going on right now | Eu tô almoçando agora. |
| vou + destination | the trip itself, planned or under way | Eu vou pra praia amanhã. |
The present continuous is its own lesson in our course, built as estar plus the -ndo form: eu estou comendo, o que você está fazendo? In conversation estou shrinks to tô and está to tá, so what reaches your ear is tô comendo. The two shapes do different jobs. If the sentence carries -ndo, it is happening now, and if it carries an infinitive after vou, it has not happened yet.
Eu vou estudar depois do jantar.
I'm going to study after dinner.
Eu tô estudando, te ligo depois.
I'm studying, I'll call you later.
A gente vai ver o jogo no bar.
We're going to watch the game at the bar.
A gente tá vendo o jogo agora.
We're watching the game right now.
One phrase deserves its own section, because Brazilians use it every time they order food and every time they sketch a plan out loud. Vou querer is the near future of querer, and it works with a thing or with another verb.
Eu vou querer o peixe.
I'll have the fish.
what you say to a waiter
Depois eu vou querer uma sobremesa.
Afterward I'll want dessert.
Amanhã eu vou querer descansar.
Tomorrow I'm going to want to rest.
A gente vai querer fazer uma reserva.
We're going to want to make a reservation.
The trap is the same one as everywhere else in this guide, and our material calls it out directly: eu vou quero instead of eu vou querer. After vou the verb stays in the infinitive, even when that verb is querer itself.
Beside the plan sits the softened version. Eu queria viajar has the shape of a past and the job of a polite wish happening now, which is the same move behind eu queria um café at the counter. Watch the preposition, the detail our course material drills as the contrast: queria takes the infinitive directly and gostaria needs de in front of it. If the past forms behind queria are the part that slows you down, our guide to pretérito perfeito vs imperfeito sorts them out.
Eu queria viajar no fim de semana.
I'd like to travel this weekend.
queria, with no de
Eu gostaria de fazer uma reserva.
I'd like to make a reservation.
gostaria, with de
Eu tô com vontade de ir ao cinema.
I feel like going to the movies.
estar com vontade de, always with de
Here is the one piece of the conjugated future you will use daily. Será is ser in the future, and será que has frozen into a fixed opener that means “I wonder” or “do you think.” It turns a flat question into a wondering, the kind you are half asking yourself.
Será que vai chover?
Do you think it's going to rain?
Será que ele chegou?
I wonder if he got here.
Será que tá aberto?
Do you think it's open?
Será que dá tempo?
Do you think there's time?
Será?
You think so?
on its own, as a reply
Learn the replies with it, because they arrive together. Acho que sim is “I think so.” Acho que não is the other way. Deve ser is “probably,” and sei lá is the shrug.
You still need this one, on the receiving end. It runs through news copy and contracts, and it is all over song lyrics. Reading it comes down to recognizing a handful of endings.
It is built on the whole infinitive with the ending stuck to the back, which makes it unusually easy to spot. Falar keeps its full shape inside falarei.
| Person | falar | comer | partir |
|---|---|---|---|
| eu | falarei | comerei | partirei |
| você / ele / ela | falará | comerá | partirá |
| nós | falaremos | comeremos | partiremos |
| vocês / eles / elas | falarão | comerão | partirão |
Four endings cover every regular verb in the language: -rei, -rá, -remos, -rão. When one of them lands at the end of a word you half recognize, strip it off and the infinitive is sitting underneath.
Three verbs shorten the stem instead of carrying the full infinitive.
| Verb | Future | Not |
|---|---|---|
| fazer | farei / fará / faremos / farão | fazerei |
| dizer | direi / dirá / diremos / dirão | dizerei |
| trazer | trarei / trará / traremos / trarão | trazerei |
| Where | What it sounds like |
|---|---|
| News headlines and reporting | O governo anunciará a medida na terça. |
| Contracts and official notices | O contrato será renovado em janeiro. |
| Speeches and ceremonies | Faremos o possível por esta cidade. |
| Song lyrics and literature | Um dia eu voltarei. |
| Speech, for weight or drama | Eu jamais farei isso. |
That last row is the honest caveat. The conjugated future has not left the spoken language, it has narrowed. A Brazilian reaches for it when a sentence needs weight, a vow or a flat refusal, then drops back to vou for the next ordinary line. Reading it costs you nothing once you know the endings. Producing it is optional for a long time.
Written down, vou falar is two words. Spoken, it is one movement of the mouth, and the reason it slips past you is not speed. It is that both ends of it change shape.
Two things happen at once. Vou is a single closed vowel rather than the two-part “oh-oo” the spelling suggests, so it lands as a short “voh” and leans straight into the verb. Then the infinitive loses the R at the end, which leaves the stress sitting on a bare vowel: an -ar verb ends on an ah, and an -er verb ends on the closed AY. What arrives is a short beat followed by a long one.
| Written | Sounds like | Meaning |
|---|---|---|
| vou falar | voh fah-LAH | I'll speak |
| vou fazer | voh fah-ZAY | I'll do |
| vou querer | voh keh-RAY | I'll have, I'll want |
| vou te ligar | voh chee lee-GAH | I'll call you |
| vai dar certo | vy dah SAY-too | it'll work out |
| vamos ver | VAH-moos VAY | we'll see |
| cê vai gostar | say vy gohs-TAH | you're going to like it |
Say the middle column out loud before you go back to the left one. If your ear is waiting for a hard R at the end of falar, the word never arrives, and you spend the rest of the sentence hunting for a verb that already went past. This joining of words is a rule that runs through the whole language, and our guide to why Brazilians sound so fast takes it apart piece by piece.
Most of the lines below are errors our course material anticipates on the day the near future is taught, in the order learners run into them.
Eu vou como no restaurante.
Eu vou comer no restaurante.
After vou the second verb stays in the infinitive. The same slip produces eu vou abro instead of eu vou abrir, and eu vou quero instead of eu vou querer.
Eu vou a falar com ele.
Eu vou falar com ele.
Nothing sits between vou and the infinitive in Brazilian Portuguese. Spanish puts an a there, which is where this one usually comes from.
A gente vão querer viajar.
A gente vai querer viajar.
A gente takes the same verb form as ele and ela, so it is a gente vai. Nós vamos querer viajar is the other correct version of the sentence.
Nós vai para o parque.
Nós vamos para o parque.
The rule runs one way only. Nós keeps the plural vamos, and a gente is the form that takes the singular.
Eu vou a o cinema.
Eu vou ao cinema.
A plus o is written and said as ao, and the contraction is not optional. The feminine pair is a plus a, written à with the crase accent.
Eu vou ao praia.
Eu vou à praia.
The gender of the place picks the contraction. Praia is feminine, so it takes à, and cinema is masculine despite the final a, so it takes ao.
Six points to keep.
Vou + infinitivo
The spoken future is ir in the present plus the dictionary form: eu vou falar, a gente vai sair.
O segundo verbo
The verb after vou never conjugates. Eu vou comer, not eu vou como.
As palavras de tempo
Amanhã, semana que vem, daqui a pouco and já já open the sentence and carry the future for you.
Ao, à, pro, pra
Going places takes a contraction, and the gender of the place decides it: vou ao cinema, vou à praia.
Será que
A fixed opener meaning 'I wonder'. The verb after it keeps its own tense: será que tá aberto?
Falarei
Recognize the endings -rei, -rá, -remos, -rão in writing and formal speech. You can read it long before you need to say it.
