The Short Answer

To say "going to" in Spanish, you use the verb ir (to go) conjugated in the present tense followed by a and then the infinitive of the action. That gives you the structure ir + a + infinitive. It's how you express the near future in everyday conversation. Voy a comer. I'm going to eat. Vas a dormir. You're going to sleep. Vamos a salir. We're going to leave. It's straightforward once you have the conjugations down. The thing that trips people up isn't the structure itself, it's knowing when NOT to use it.

How To Say Going To In Spanish: The Conjugation Breakdown

You need the present tense of ir, which is irregular and won't forgive you for assuming it follows a normal pattern. Here it is: Yo voy — I go / I'm going
Tú vas — you go / you're going
Él/Ella/Usted va — he/she goes, you formal go
Nosotros/as vamos — we go / we're going
Vosotros/as vais — you all go (Spain only, rarely used elsewhere)
Ellos/Ellas/Ustedes van — they go, you all go After the conjugated form, you add a and the infinitive. So "I'm going to study" becomes Voy a estudiar. "They're going to travel" is Van a viajar. The infinitive never changes regardless of who the subject is. That's one fewer thing to worry about.

I spent a couple hours one evening trying to explain this to someone who kept inserting the wrong preposition. They'd write "Voy para estudiar" which sounds like "I'm going in order to study" — directionally and purposefully different. The structure is always a, not para, not en. Just memorize that as a hard rule and you'll be fine.

When This Structure Actually Gets Complicated

The ir + a + infinitive construction works for most practical purposes, but it breaks down in specific contexts. Here are the ones that matter. Formal writing and literature. If you're reading a novel or a news article from Spain, you'll encounter the perífrasis verbal in its various forms, and sometimes the future simple is preferred over the going-to construction. A writer might say Comeré tarde instead of Voy a comer tarde. Both are correct, but the simple future sounds more formal and less conversational. In casual speech, nobody uses the simple future much in Spain. It's nearly extinct in everyday conversation there. LatAm vs. Spain differences. In many Latin American countries, the simple future tense (haré, comeré) is more common in both speech and writing than it is in Spain. The ir + a + infinitive structure is still perfectly correct and widely used, but you'll hear the synthetic future more often. This doesn't mean one is better. It means your listening comprehension needs to cover both.

When "going to" means physical movement. This is the big one. If you're talking about literally going somewhere, you can't just slap a + infinitive onto ir and expect the meaning to come through. Voy a la tienda means "I'm going to the store" — physical location. Voy a estudiar means "I'm going to study" — future action. The same verb, totally different constructions depending on whether a is followed by a noun or a verb. I once saw a student write Voy a restaurante when they meant the future tense, and the sentence just didn't parse to a native speaker. It sounded like they were announcing they were walking to a restaurant building, not that they would eat there later.

The Edge Case That Actually Matters

Here's something most textbooks don't emphasize enough. When you use ir + a + infinitive, the a contracts to al if the following noun starts with "a" or "ha" in the masculine singular. This matters less with the infinitive construction since infinitives are verbs, but it comes up constantly in other uses of ir that learners confuse with the future tense. For example, Voy al cine not Voy a el cine. Native speakers correct this constantly, and if you say "voy a el," it marks you immediately as a learner. There's also the issue of pronoun placement. With the periphrastic future, you can attach object pronouns to the infinitive: Voy a comerlo (I'm going to eat it). Or you can put them before the conjugated verb: Lo voy a comer. Both are correct. The first is slightly more common in speech. The second is preferred in formal writing. Neither is wrong, and native speakers switch between them without thinking about it. But if you're learning from a textbook that only shows one version, you'll sound stiff when you actually talk to someone. I ran into a real problem with this once while helping a friend with her homework. She had a sentence: Ella va a leerlo. Her teacher marked it wrong and wanted ella lo va a leer. I checked three different grammar sources and they all confirmed both are correct. The teacher had a personal preference, not a rule. This happens more often than you'd think with Spanish grammar. What's "right" in a classroom sometimes doesn't match what actual speakers do.

Common Mistakes That Waste Time

Forgetting the preposition. Saying Voy estudiar instead of Voy a estudiar. It's the most frequent error I see, even among people who've studied Spanish for years. The a is mandatory. There's no exception. Conjugating the infinitive. Voy a estudias or Voy a comió. The infinitive stays in its base form. Never change it. Ever. This one is relatively rare but when someone does it, it stands out badly. Using the wrong person. Tú vais a comer instead of tú vas a comer. Mixing up vos/vosotros conjugations depending on which region you're in. If you're in Mexico, vosotros forms don't exist in everyday speech. If you're in Madrid, avoiding them entirely will make you sound like a tourist. Know your audience.

Confusing it with "want to." Querer and ir a can both translate to "going to" in English, but they mean different things. Voy a ir is future intention. Quiero ir is desire. Voy a ir implies you've already decided. Quiero ir implies you'd like to but might not actually do it. Mixing these up changes the meaning significantly, and native speakers notice immediately.

What This Structure Can't Do

The ir + a + infinitive construction only works for the near future. It's not a general-purpose future tense. If you're talking about something that will happen next year, ten years from now, or in an abstract hypothetical sense, this structure sounds odd or even wrong. Voy a morir sounds like you're about to die right now. Voy a ser famoso sounds like it's happening tomorrow, not sometime in your lifetime. For distant or uncertain futures, the simple future (seré, moriré) or the subjunctive in certain contexts is more appropriate. There's also no way to express "I'm going to have done X" or other compound future tenses with this structure. If you need I'll have finished by Monday, you're stuck with the future perfect (habré terminado). The periphrastic future has no compound form. This is a genuine limitation that intermediate learners hit fairly quickly. Another practical constraint: the structure doesn't work well in passive voice contexts. La carta va a ser escrita is grammatically correct but clumsy. Native speakers would rephrase this entirely rather than push the periphrastic future through a passive construction. It's not that it's impossible. It's that it sounds unnatural and you'd be better off finding a different way to say it.

Practical Usage Tips

Listen to native speakers and notice how often they use this structure versus the simple future. In Spain, the ratio is heavily in favor of ir + a + infinitive. In Latin America, the balance shifts depending on the country. Colombia uses it constantly. Argentina uses the simple future more than most. Chile is somewhere in between. If you're learning Spanish for a specific region, tailor your listening practice to that dialect. Practice by turning simple statements into future tense ones. Take something you know how to say now and add voy a in front of it. Estudio español becomes Voy a estudiar español. Como pizza becomes Voy a comer pizza. Do this for ten minutes and you'll internalize the pattern faster than any worksheet will get you to. Record yourself saying sentences and compare them to native speech. Your pronunciation of voy a might sound like two separate words to you, but natives often blend it into something closer to "boya" in rapid speech. That's normal. Don't try to over-enunciate it. The slight reduction is expected and natural.
