Ir a + infinitive: the easiest way to talk about the future in Spanish

One verb you already know, a tiny "a", and any verb you like. That's all you need to talk about your plans in Spanish.

En resumen (the short version)

  • Ir a + infinitive is the Spanish "going to": Voy a cenar fuera (I'm going to eat out). Only ir changes. The a and the second verb never do.
  • Pronouns go before ir or on the end of the infinitive: Te voy a llamar or Voy a llamarte. Never in the middle.
  • Add a time word, like mañana or el lunes, and you can talk about any plan.

¡Hola aventurero!

What are you doing this weekend? 🤔

If you can answer that in English, you can answer it in Spanish. With one verb. Today I'll show you how ir a + infinitive works, and the little details that make it sound natural.

If you know voy, vas and va, you've already done the hardest part. En serio.

Why "going to" works in both languages

Teacher bit 🤓 English and Spanish did the same thing with the verb "go". Both turned it into a way of talking about the future.

Think about it: when you say "I'm going to cook", you're not going anywhere. You're "moving towards" the action. Spanish uses ir in exactly the same way:

English and Spanish both use "go" for the future
EnglishSpanish
II'm going to cook.Voy a cocinar.
YouAre you going to come?¿Vas a venir?
WeWe're going to win!¡Vamos a ganar!

So it isn't a new idea at all. It's an English idea with Spanish words in it.

The formula: three pieces

Every ir a sentence has the same three pieces:

The three pieces of ir a + infinitive
1. Ir (this changes)2. a (never changes)3. Infinitive (never changes)
Voyabailar.
¿Vasavenir?
Vamosacelebrarlo.

The infinitive is the dictionary form of a verb, ending in -ar, -er or -ir. Here's ir with everyone, planning a birthday party 🎂

Ir a with every person
Ir aExampleIn English
voy aVoy a hacer una tarta de chocolate.I'm going to make a chocolate cake.
vas a¿Vas a venir a la fiesta?Are you going to come to the party?
va aMi hermana va a traer la música.My sister's going to bring the music.
vamos aVamos a cenar en el jardín.We're going to have dinner in the garden.
vais a¿Vais a quedaros a dormir?Are you all going to stay the night?
van aMis padres van a llegar tarde.My parents are going to be late.

Vais is the one you'll hear in Spain when someone talks to a group of friends. Lots of courses skip it, so it's worth a second look.

Lucía's tip: colour the pieces

When you write ir a sentences in your notes, use one colour for ir and another for the infinitive. You'll see straight away that only the first colour ever changes.

Where do pronouns go?

This is the bit most learners get stuck on. Words like me, te, lo and se can go in two places, and both are correct:

Two places for pronouns with ir a
Before irOn the end of the infinitiveIn English
Te voy a llamar.Voy a llamarte.I'm going to call you.
Lo vamos a celebrar.Vamos a celebrarlo.We're going to celebrate it.
Me voy a duchar.Voy a ducharme.I'm going to have a shower.
Se lo voy a decir.Voy a decírselo.I'm going to tell him.

Pick whichever comes out first. People in Spain use both all the time.

Look at the last row. When you stick two pronouns on the end, decir becomes decírselo, with an accent. The word gets longer, so the accent is there to keep the stress where it was: de-CÍR-se-lo.

¡Ojo! (Watch out)

The one place a pronoun can't go is in the middle. Voy a te llamar and Voy te a llamar are both wrong. Before ir, or glued to the end. Nothing in between.

Verbs like ducharse are reflexive verbs. If those still confuse you, there's a whole post on Spanish reflexive verbs.

Saying when

A plan needs a when. Here are some time words, from soonest to furthest away:

Time words for your plans, from soonest to latest
SpanishEnglish
luegolater (today)
esta tardethis afternoon / this evening
mañana por la mañanatomorrow morning
el luneson Monday
el mes que vienenext month
el próximo veranonext summer
dentro de un añoin a year's time
algún díaone day

Two things to notice. Mañana por la mañana looks funny, but mañana means both "tomorrow" and "morning" 😄 And days of the week take el, not en: El lunes voy a empezar el gimnasio (On Monday I'm going to start the gym). Seguro que sí.

For things that are about to happen

Ir a isn't only for plans. You also use it when you can see something coming, right now:

Ir a for things you can see coming
SpanishEnglish
¡Cuidado, que te vas a caer!Careful, you're going to fall!
La cena se va a enfriar.Dinner's going to get cold.
Esto va a ser difícil.This is going to be hard.
¡Vamos a llegar tarde!We're going to be late!

Notice the que in the first one. In Spain, people often put que after a warning or a request, a bit like "because". You'll hear it everywhere.

Good to know

Spanish also has a one-word future: iré (I'll go), comeré (I'll eat), será (it'll be). It's good to recognise when you read or hear it. But for everyday plans in conversation, ir a is what you'll hear most, so start there.

Hear it in a conversation

Two friends talking about plans for a long weekend, el puente:

A
¿Qué vas a hacer en el puente?What are you doing over the long weekend?
B
Vamos a ir a la sierra con unos amigos. ¿Y tú?We're going to the mountains with some friends. What about you?
A
Yo me voy a quedar en casa. Voy a pintar el salón.I'm going to stay at home. I'm going to paint the living room.
B
¡Vaya plan! ¿Lo vas a pintar tú solo?Some plan! Are you going to paint it on your own?
A
No, mi hermano me va a ayudar. Bueno, eso dice…No, my brother's going to help me. Well, that's what he says…
B
Pues va a llover el sábado, así que es buen momento.Well, it's going to rain on Saturday, so it's a good time.
A
¿Sí? Entonces vais a pasar frío en la sierra.Really? Then you're going to be cold in the mountains.
B
Ya… Voy a llevarme el abrigo gordo.I know… I'm going to take my big coat.

Spot the pronouns: me voy a quedar puts it before ir, and voy a llevarme puts it on the end ✨

Common mistakes

❌ The mistake

Voy cocinar esta noche. Leaving out the a.

✅ Instead

Voy a cocinar esta noche. The a is always there.

❌ The mistake

Vamos a vemos una película. Changing the second verb too.

✅ Instead

Vamos a ver una película. Only ir changes.

❌ The mistake

Voy a me duchar. Putting the pronoun in the middle.

✅ Instead

Me voy a duchar or Voy a ducharme.

❌ The mistake

En el lunes voy a llamarte. Using en with days.

✅ Instead

El lunes voy a llamarte.

Practise it this week

  1. Plan your weekend out loud

    Say three plans for this weekend, each with a different time word: El sábado por la mañana voy a ir al mercado. Por la tarde voy a ver una película. El domingo voy a descansar.

  2. Say every pronoun sentence both ways

    Pick three sentences with a pronoun, like Te voy a llamar, and say each one both ways: Te voy a llamar and Voy a llamarte. Your mouth gets used to both.

  3. Ask someone about their plans

    Next time you speak Spanish, ask ¿Qué vas a hacer este finde? and have your own answer ready too.

And after the weekend? You'll need the past to say how it went, so how to talk about your weekend in Spanish is the natural next step.

Recap ✨

  1. Ir a + infinitive is the Spanish "going to": Voy a cocinar.
  2. Only ir changes. The a and the infinitive never do.
  3. Pronouns go before ir or on the end of the infinitive: Te voy a llamar or Voy a llamarte. Never in the middle.
  4. Days take el, not en: El lunes voy a…
  5. Use ir a for plans and for things you can see coming: ¡Te vas a caer!
