In this article, you’re going to find out how to express the future tense in Spanish using a neat little construction: ‘ir a + infinitive.’

Spanish Ir A

Two Types of Future Tense in Spanish

In Spanish, there are two forms of the future tense. One of them, the “proper” future tense, is a little more complicated and is explained in a separate article. It’s formed by finding a stem from the infinitive of the verb, then adding the appropriate future tense endings.

The form that we’ll look at in this lesson is simpler! It’s used as an informal version of the future tense, and, in spoken Spanish, it’s used way more than the proper future tense. Use this when you’re speaking Spanish, and you’ll sound like a pro in no time! 

It’s also used to express firm intention, e.g. ¡Voy a lograrlo! (I will manage it!)

How to Form the Informal Future Tense in Spanish

Believe it or not, this is one of the simplest Spanish verb tenses to form. All you have to do is:

  1. 1
    Conjugate the verb ir (‘to go’) in the present tense.
  2. 2
    Add the word a (‘to’).
  3. 3
    Add the infinitive of whichever verb you want to use!

So for this tense, the only thing you need to know how to conjugate is the verb ir. Here’s how to do it in the present tense:

(yo) voy(nosotros/as) vamos
(tú) vas(vosotros/as) vais
(él/ella/usted) va(ellos/ellas/ustedes) van

So, ‘voy a hacer algo’ means ‘I am going to do something.’

Time to see some more examples.

Voy a cocinar.I am going to cook.
Voy a viajar por el mundo.I’m going to travel the world.
¿Cuándo vas a devolverme el dinero?When are you going to give me my money back?
No vas a olvidarme.You won’t forget me.
Manuela va a aprobar el examen. Estoy seguro.Manuela is going to pass the exam. I’m sure of it.
Usted va a tener acceso a todas partes del museo.You (formal) will have access to all parts of the museum.
Vamos a ser famosos.We’re going to be famous.
Vamos a ver.Let’s see (literally: we are going to see).
¿Vais a venir a la fiesta?Are you (plural) going to come to the party?
Vais a casaros este fin de semana, ¿verdad?You (plural) are getting married tomorrow, right?
Los edificios viejos van a ser destruidos.The old buildings are going to be destroyed.
Ustedes van a quedarse en el mejor hotel de la ciudad.You (formal plural) are going to stay in the best hotel in the city.

Using the Future in the Past

Okay, so “using the future in the past” sounds a bit crazy, but it will make sense with some examples. 

Imagine you want to say ‘I was going to study but I forgot.’ (Haven’t we all been there? Forgot, got distracted, fell asleep...) You’ll need to put ir in the imperfect tense (‘I was going to …’)

We use the same rules as earlier:

  1. 1
    Conjugate the verb ir (‘to go’) but this time in the imperfect tense.
  2. 2
    Add the word a (‘to’).
  3. 3
    Add the infinitive of whichever verb you want to use!

Here’s how to conjugate ir in the imperfect tense:

(yo) iba(nosotros/as) íbamos
(tú) ibas(vosotros/as) ibais
(él/ella/usted) iba(ellos/ellas/ustedes) iban

So, in our accidentally-forgetting-to-study example:

  1. 1
  2. 2
  3. 3

Simple as that.

Iba a estudiar pero se me olvidó.I was going to study but I forgot.
¿No ibas a estudiar hoy?Weren’t you going to study today?
El agresor iba a golpearme así que le di una patada entre las piernas.The attacker was going to hit me so I kicked him between the legs.
Cantaremos en la obra. Prometimos que íbamos a hacerlo.We will sing in the show. We promised that we would (were going to) do so.
Ibais a leer mi libro, ¿no?You were going to read my book, weren’t you?
Los dos iban a renunciar al amor, pero todo cambió en cuanto se conocieron.Both of them were going to give up on love, but everything changed as soon as they met each other.

¡Ojo! (Beware!)

When you see an ir a construction, don’t just assume it’s a future tense. For example, if it’s ‘ir a + place name’ rather than ‘ir a + infinitive’ then it’s just talking about going somewhere. When you come across it in text, the context should make it clear what’s going on.

These examples aren’t examples of the future tense, even though they contain voy a.
Voy a China el mes que viene.I’m going to China next month.
Voy a una reunión.I’m going to a meeting.
