Spanish Grammar — The Informal Future

Section 13.1  ·  The most natural way to talk about future plans · [ir conjugated] + a + [infinitive] · voy a trabajar · vas a comer · va a llegar · vamos a estudiar · any verb works as the infinitive · no new endings to learn

📖 Introduction — Chapter 13: Planning the Future

In this chapter you learn how to look ahead. Discussing upcoming events, appointments, and personal goals is essential in any professional or social setting — whether you are scheduling a follow-up meeting, coordinating with colleagues, or planning a weekend trip. The structures in this chapter let you share your intentions clearly and confidently.

Section 13.1 introduces the informal future, which is by far the most widely used way to express future plans in everyday Spanish throughout the Americas. The beauty of this structure: you already know everything you need. It combines the verb ir (which you mastered in Section 12.2) with the word a and any infinitive. No new verb endings. No new conjugations. Just a formula: [ir] + a + [infinitive]. The infinitive never changes — it always stays in its original form regardless of who the subject is.

[ir conjugated] + a + [infinitive] = informal future tú → vas a + infinitive infinitive NEVER changes — only ir is conjugated the most natural future in spoken Spanish works with ANY verb as the infinitive stem-changing verbs also work: voy a pedir, vamos a almorzar

💡 The Formula: [Ir] + a + [Infinitive]

Step 1 — Conjugate Ir
voy / va
vamos / van

Step 2
a
+
Step 3 — Any Infinitive

comer / vivir
Yo

+ a +
vas a comer
Usted / Él / Ella
va
+ a +
va a vivir
Nosotros

+ a +
vamos a estudiar
Ustedes / Ellos
van
+ a +
van a visitar
The golden rule:  Only ir changes to match the subject. The infinitive is frozen — it never changes, no matter who the subject is. Yo voy a trabajar. Tú vas a trabajar. Usted va a trabajar. Nosotros vamos a trabajar. Ustedes van a trabajar. The word “trabajar” stays identical every time.

🔁 Present vs. Informal Future — Spot the Difference

Present Tense (Now / Habitually)

Yo trabajo en la oficina.
I work in the office. (I do this.)

comes en casa.
You eat at home. (You do this.)

Usted come en el hospital.
You eat at the hospital. (You do this.)

Nosotros estudiamos español.
We study Spanish. (We do this.)

⏰ Informal Future (Upcoming Plans)

Yo voy a trabajar mañana.
I am going to work tomorrow.

vas a comer en casa.
You are going to eat at home.

Usted va a comer en el hospital.
You are going to eat at the hospital.

Nosotros vamos a estudiar español.
We are going to study Spanish.

Pattern:  The present tense verb (trabajo, come, estudiamos) becomes a two-part structure in the informal future: conjugated ir + a + that same verb in infinitive form (voy a trabajar, va a comer, vamos a estudiar). The infinitive always ends in -ar, -er, or -ir and never changes.

1. The Formula — [Ir] + a + [Infinitive]

only ir changes · infinitive stays frozen · works with any -ar / -er / -ir verb

The informal future is built on one rule: conjugate ir to match the subject, add a, then place any verb in its infinitive form. The infinitive never changes. Yo voy a trabajarTú vas a trabajarUsted va a trabajarUstedes van a trabajar. The word trabajar is identical every time. Once you know all five forms of ir (including vas for tú), you can express future plans with any verb you have learned. No new endings, no stem changes in the infinitive.

Why is this called the “informal future”? Spanish has a formal future tense with its own set of verb endings (hablaré, hablarás...). But in everyday spoken Spanish throughout the Americas, the ir + a + infinitive structure is used far more often for future plans, intentions, and predictions. It sounds natural and conversational. You will learn the formal future later — for now, this structure covers virtually all your future communication needs.
✏️ Example Sentences — the formula in action:
  1. Yo voy a trabajar mañana — tengo mucho que hacer.
  2. Tú vas a estudiar esta noche, ¿verdad?
  3. Usted va a comer en el hospital durante su turno de hoy.
  4. Nosotros vamos a estudiar español esta tarde en la biblioteca.
  5. Ustedes van a visitar la oficina nueva el próximo lunes.
  6. ¿Qué vas a hacer tú hoy después de clase?

2. Personal Intentions — Voy a ___

voy a + infinitive · stating your own plans · sounds natural and confident

The yo form voy a ___ is the workhorse of personal planning in Spanish. Use it to state what you intend to do: Voy a enviar el correo ahora (I am going to send the email now), Voy a llamar al doctor (I am going to call the doctor), Voy a terminar la tarea pronto (I am going to finish the assignment soon). This construction sounds confident and decided — it communicates that something is genuinely planned, not just a vague possibility. In professional settings, voy a ___ is how you commit to a deliverable: Voy a enviar el reporte antes de las cinco (I am going to send the report before five). Note that every infinitive in these examples ends in -ar, -er, or -ir and stays completely unchanged.

Voy a vs. Quiero: Both express desire or intention, but with a subtle difference. Quiero trabajar (I want to work — desire). Voy a trabajar (I am going to work — plan/commitment). The ir + a structure is stronger and more concrete than querer — it implies the action is actually planned, not just wished for.
✏️ Example Sentences — voy a (personal intentions):
  1. Yo voy a enviar el correo ahora — ya está listo para enviar.
  2. Yo voy a llamar al doctor esta tarde para confirmar la cita.
  3. Yo voy a leer el reporte técnico después del almuerzo.
  4. Yo voy a comprar agua para la reunión de las tres.
  5. Yo voy a terminar la tarea pronto — solo me falta un poco.

3. Professional Schedules — Va a / Vamos a / Van a

coordinating with colleagues · relaying plans · third-person future announcements

The va a / vamos a / van a forms are essential for coordinating in professional settings. El gerente va a asistir a la reunión (The manager is going to attend the meeting) — reporting someone else's plan. Nosotros vamos a presentar el plan (We are going to present the plan) — announcing a team commitment. Ustedes van a organizar los documentos (You all are going to organize the documents) — delegating. El técnico va a reparar la computadora (The technician is going to repair the computer) — informing about a scheduled service. In each case, the infinitive — asistir, presentar, organizar, reparar — stays unchanged regardless of subject. These sentences cover the core of workplace communication about future actions.

✏️ Example Sentences — professional schedules:
  1. El gerente va a asistir a la reunión de las diez de la mañana.
  2. Nosotros vamos a presentar el plan al cliente el próximo viernes.
  3. El técnico va a reparar la computadora mañana por la mañana.
  4. Usted va a recibir un mensaje de confirmación en su correo.
  5. Ustedes van a organizar los documentos antes del viernes.

4. Asking About Plans — ¿Va a ___? / ¿Vas a ___? / ¿Qué vas a ___?

question words + va a / vas a · formal: ¿va a hacer? · informal: ¿vas a hacer? · polite and organized

The informal future is equally powerful for forming questions. For formal questions directed at usted, use ¿Qué va a hacer usted?. For informal questions directed at tú, use ¿Qué vas a hacer tú? (What are you going to do?). Both follow the same formula: question word + [ir form] + a + infinitive. Common question words: ¿A qué hora vas a salir? (What time are you going to leave? — informal), ¿Cuándo vas a estudiar? (When are you going to study?), ¿Dónde va a vivir su familia? (Where is your family going to live?). These questions sound polished and professional in any workplace or social setting.

Va a vs. Vas a in questions: ¿Qué va a hacer usted? = formal (usted). ¿Qué vas a hacer tú? = informal (tú). The structure is identical — only the ir form changes to match who you are asking.
✏️ Example Sentences — asking about plans:
  1. ¿Qué vas a hacer tú esta tarde después de clase?
  2. ¿A qué hora vas a salir del trabajo hoy?
  3. ¿A qué hora va a salir usted de la oficina esta tarde?
  4. ¿Cuándo va a empezar la clase de español el próximo mes?
  5. ¿Dónde va a vivir su familia después de la mudanza?
  6. ¿Vas a viajar tú este fin de semana o vas a quedarse en casa?

5. Using Any Verb as the Infinitive — Including Stem-Changers

stem-changers stay unchanged as infinitives · querer · almorzar · pedir · poder · volver

One of the most liberating features of the informal future: any verb works as the infinitive, including all the stem-changing verbs from Chapters 11 and 12. When a stem-changing verb appears as the infinitive in this structure, it does not change — it stays in its plain infinitive form. Usted va a querer un café (not “va a quiere”), Nosotros vamos a almorzar juntos (not “vamos a almorzamos”), Yo voy a pedir la cuenta (not “voy a pido”). The stem change only applies when the verb is conjugated — in the infinitive position, it is completely neutral. This means you now have access to the full vocabulary you have built across all chapters for talking about the future.

Critical rule — infinitive never stem-changes: Stem changes happen in conjugated forms (pido, puede, quiere). In the infinitive position after ir + a, the verb is NOT conjugated, so no stem change occurs. Voy a pedir (not “voy a pido”). Va a poder (not “va a puede”). Vamos a querer (not “vamos a queremos”). The infinitive form is always the safe, unchanged form.
✏️ Example Sentences — stem-changing infinitives:
  1. Tú vas a querer un café después de esa clase tan larga.
  2. Usted va a querer un café después de la reunión larga.
  3. Nosotros vamos a almorzar juntos el próximo viernes.
  4. Yo voy a pedir la cuenta — la reunión ya casi termina.
  5. Ustedes van a poder entrar pronto — la sala casi está lista.
  6. Él va a volver el lunes — estuvo de viaje toda la semana.

📌 Key Rules — The Informal Future at a Glance:

Shadow & Speak — Section 13.1-A

Listen to each sentence in Spanish, then repeat aloud during the countdown pause.

Sentences 1–6 drill all five ir forms including vas a ___ (tú) alongside voy a, va a, vamos a, and van a. Sentences 7–11 practice voy a ___ for personal intentions. Sentences 12–16 use va a / vamos a / van a for team coordination and third-person announcements. Sentences 17–22 drill future questions with both informal vas a and formal va a. Sentences 23–30 use stem-changing verbs as infinitives and mix all five ir forms including tú.

How to Shadow & Speak

Step 1 — Identify the ir form: Before repeating, spot the conjugated ir: voy / vas / va / vamos / van. Confirm the subject matches. Remember: vas signals tú (informal you).

Step 2 — Say the infinitive flat: The infinitive is always in its base form. As you repeat, make sure you are not adding any extra ending to it. Say it cleanly: vas a traba-jar, not vas a trabajas.

Step 3 — Three-part rhythm: Say the sentence in three beats: [ir form] — [a] — [infinitive]. Vas — a — estudiar. This rhythm locks in the structure as a single chunked pattern.

Study Tips

The weekly planner drill: Every morning, say five things you are going to do: Voy a ___ with five different infinitives. Then try the same five with vas a ___ (as if telling a friend their plans). This builds both the yo and tú forms simultaneously.

The five-subject rotation: Take any infinitive (for example, terminar) and say it with all five ir forms: Voy a terminar — vas a terminar — va a terminar — vamos a terminar — van a terminar. This five-beat drill locks in every conjugation and the unchanging infinitive in one exercise.

Stem-changer confirmation: Take five stem-changing verbs (querer, poder, pedir, almorzar, volver) and confirm the infinitive with both vas a and voy a: vas a querer (not quieres) · voy a poder (not puedo) · vas a pedir (not pides). Saying the wrong form aloud and correcting it is one of the fastest ways to eliminate this error.
