Ir a + Infinitive: Talking About Plans in Spanish
Voy a llamar mañana: use ir a + infinitive for plans in Spanish — the six forms of ir, going to a place vs going to do something, and common mistakes.
English says “I'm going to call.” Spanish builds almost the same sentence: voy + a + llamar. It's one of the easiest ways to talk about the future, because only one thing changes: the form of ir. The a is always there, and the second verb always stays in the infinitive — llamar, comer, salir.
The formula: ir + a + infinitive
Ir (to go) is irregular, so its six present forms are worth learning as a set. Everything after them stays the same.
The vosotros form (vais a) is the informal “you all” of Spain; in Latin America, ustedes van a covers every plural “you.” As usual, the subject pronoun is often dropped: Voy a llamar is enough.
Plans and things about to happen
Plans and intentions. The most common use: saying what you (or others) have decided to do.
El lunes vamos a empezar el curso. (We're going to start the course on Monday.)
Mis padres van a comprar un coche. (My parents are going to buy a car.)
What looks about to happen. When you can see the signs, ir a works like English “it's going to…”.
¡Corre, el autobús va a salir! (Run, the bus is about to leave!)
Time words. These often go at the start or the end of the sentence. For “next,” both que viene and próximo/a are common and correct.
la semana que viene = la próxima semana (next week)
el año que viene = el próximo año (next year)
Good to know: Spanish also uses the plain present for fixed near plans — Mañana trabajo. — and it has a one-word future (llamaré, lloverá) that you'll meet later. In everyday conversation, ir a + infinitive is extremely common everywhere, and in much of Latin America it's the usual spoken way to talk about the future; the one-word future is more frequent in writing and formal speech.
Going to a place vs going to do something
After ir a, look at the next word. A place names the destination; an infinitive often expresses a plan or a prediction. Depending on the context, ir a + infinitive can also describe going somewhere to do something.
Voy a viajar a Madrid. (I'm going to travel to Madrid — a plan.)
Voy al cine. (I'm going to the movies — a + el = al, before a place.)
Al (a + el) appears before a noun that takes the article el: al cine, al parque. In ir a + infinitive there is no el, so it stays plain a: Voy a comer, never “voy al comer.” And the two can combine: Voy a ir al cine (I'm going to go to the movies) is completely normal.
Negatives, questions and pronouns
No goes before the verb group. With no pronoun, it comes directly before ir; with a pronoun before ir, it precedes the pronoun: No lo voy a comprar (“I am not going to buy it”). Yes/no questions can keep the statement’s word order and use question intonation. Questions with qué, cuándo or another question word usually start with that word.
¿Vas a venir a la fiesta? (Are you going to come to the party?)
¿Qué vas a hacer el sábado? (What are you going to do on Saturday?)
Two places for pronouns. A short pronoun like lo or la can go before ir or be attached to the end of the infinitive. Both are correct everywhere; just don't put it between the two parts.
Me voy a acostar tarde. = Voy a acostarme tarde. (I'm going to go to bed late.)
One more thing: vamos a + infinitive can also mean “let's…”. Said as an invitation, ¡Vamos a comer! means “Let's eat!”; as a plain statement, Vamos a comer a las dos means “We're going to eat at two.” Context and intonation tell you which.
Common mistakes
Dropping the a. The a links ir and the infinitive, like “to” in “going to call.” It can't be left out.
✓Voy a llamar mañana.
Conjugating the second verb. Only ir shows the person; the verb after a stays in the infinitive.
✓Voy a llamar mañana.
The wrong form of ir. Va a is easy to learn as one chunk, but ir must agree with the subject: yo takes voy.
✓Yo voy a estudiar.
Copying the English -ing. “I'm going to” has -ing, but Spanish uses the simple present of ir here, not estar + yendo.
✓Voy a llamar mañana.
Not a mistake: “vamos a la playa mañana.” Learners sometimes think a future plan must use vamos a ir. It doesn't have to — both sentences are correct.
✓Vamos a ir a la playa mañana.
The first uses the present of ir with a future time word; the second uses ir a + infinitive. The meaning is practically the same.
Quick exercise
Complete each sentence with the right form of ir a + the verb in brackets.
- Mañana (yo) ___ a mi madre. (llamar)
- ¿Qué ___ (tú) este fin de semana? (hacer)
- El cielo está muy gris: ___. (llover)
- Esta noche (nosotros) no ___. (salir)
- Marta y Luis ___ una casa en el campo. (comprar)
- ¿___ (vosotros) a la fiesta el sábado? (venir)
- Usted ___ el tren de las ocho. (tomar)
- Esta tarde (yo) ___ al gimnasio. (ir)
Answer key
- voy a llamar (yo → voy; the second verb stays in the infinitive)
- vas a hacer (tú → vas; a question with qué)
- va a llover (you can see the signs — it's about to happen)
- vamos a salir (no stays before the form of ir)
- van a comprar (Marta y Luis = ellos → van)
- Vais a venir (vosotros → vais; in Latin America you'd hear ¿Van a venir…? with ustedes)
- va a tomar (usted uses the él/ella form → va)
- voy a ir (ir a + ir is normal: the plan is “to go”; al gimnasio is the place)
