Choose the right form of ir
The present forms of ir are voy, vas, va, vamos, vais, van. They are irregular, so do not try to produce them by attaching regular endings to a shortened infinitive. In a plan, the subject determines which of these forms you choose. The speaker uses voy, a familiar singular listener with tú uses vas, and a group containing the speaker uses vamos. Singular usted shares va with he and she, while plural ustedes shares van with they. Familiar plural vosotros uses vais where that address form is part of the local system. These person choices are independent of the time phrase: tomorrow does not give every subject the same verb. Practice switching from your own plan to another person’s plan before adding several new activities. That isolates the part of the construction that actually changes.
Yo voy a estudiar esta tarde.
I am going to study this afternoon.
The subject is the speaker, so the finite form is voy. The following a estudiar names the planned activity without taking another person ending.
Mis amigos van a cocinar.
My friends are going to cook.
The plural subject means they, requiring van. The planned action stays in the infinitive cocinar even though more than one person will perform it.

Keep a and the infinitive together
The construction has three necessary parts: a finite form of ir, the preposition a, and an infinitive. A common beginner error drops a because the speaker concentrates on the two verbs. Another error conjugates the final verb too, producing two finite forms where the construction requires one. Think of the first verb as the place where you mark person and the second as the name of the event. Vamos a comer therefore changes to Van a comer when the subject changes, while a comer remains stable. The infinitive can be regular or irregular in other tenses; its dictionary form still appears here. This makes the construction useful early in learning because you can express many plans without knowing the full future paradigm of each main verb. Its usefulness does not remove the need to preserve the small connecting word.
Nosotros vamos a comer pronto.
We are going to eat soon.
The preposition a connects the finite form of ir to the infinitive. It remains required even though it is a short unstressed word in ordinary speech.
Ana va a hacer la cena.
Ana is going to make dinner.
Only va is finite. The action verb remains hacer, so its irregular present form is not needed in this position.
Follow a complete example
Build a sentence with this meaning: We are going to eat soon. Before looking at the answer, identify which information controls the grammatical choice.
- First, identify the message: We are going to eat soon. Keep that message fixed while comparing forms. A sentence can be grammatical yet communicate something different, so meaning is part of the decision.
- The preposition a connects the finite form of ir to the infinitive. It remains required even though it is a short unstressed word in ordinary speech.
- Now read the complete sentence, Nosotros vamos a comer pronto. Check the words surrounding your choice as well as the choice itself. Explain what would change if the speaker, number, or intended message changed. Then cover this example and reconstruct the sentence from the English cue.
Nosotros vamos a comer pronto. We are going to eat soon.

Build negatives and questions around the finite verb
For an ordinary negative plan, put no before the finite verb: No voy a salir. The event infinitive stays unchanged. A confirmation question uses the same complete construction with question punctuation and appropriate intonation, as in ¿Vas a estudiar? Spanish does not add an English style do helper, and it does not move the preposition away from the infinitive. The answer may repeat the construction or use a shorter reply when the activity is already clear. If you repeat it, change the person to the answerer’s viewpoint: a question addressed to you may receive a reply about me. Be careful with negative questions, which can carry expectations or reactions beyond a simple neutral request for information. This lesson practices straightforward affirmative questions and negative statements so that the basic verb group becomes dependable before those conversational nuances are added.
Yo no voy a salir hoy.
I am not going to go out today.
The negative marker precedes the finite speaker form voy. The infinitive salir names the denied plan and does not lose its ordinary dictionary form.
¿Usted va a viajar mañana?
Are you going to travel tomorrow, using usted?
The listener is addressed with singular usted, so the finite form is va. Question punctuation changes the communicative purpose without changing the required person agreement.

Distinguish a planned action from a destination
A movement sentence such as Voy a Madrid names a destination after a. A plan such as Voy a trabajar contains an infinitive and may describe a future action without literal travel. Context can sometimes support more than one interpretation, because working may also require going somewhere. The point is to inspect what follows a rather than deciding from the English word going alone. You can also use the verb ir as the main infinitive in its own future construction: Voy a ir al museo. That repetition is grammatical. The first form supplies the planning construction; the later infinitive expresses the planned movement. When a destination uses masculine singular el, a and el normally combine as al. Keep the grammar of that destination phrase separate from the earlier a that introduces the infinitive. A sentence can contain both relationships at once.
Voy a ir al museo.
I am going to go to the museum.
The first voy builds the future construction, while the infinitive ir names the planned movement. Repeating the same verb family in these two roles is grammatical.
Vamos a visitar a Ana.
We are going to visit Ana.
The plan uses an infinitive after vamos a. The later a before Ana belongs to a separate personal object pattern and does not replace the earlier connector.

Use the construction for intentions and predictions
Ir a commonly presents an intention, but a future event need not be under someone’s control. A prediction about rain can also use the construction. Identify whether you are reporting a decision or an expectation rather than assuming the grammar always guarantees a deliberate plan. Similarly, the label near future can be misleading if it suggests a strict number of minutes or days. Context may place the event tomorrow, next month, or farther away. A time phrase helps the listener locate it. Other Spanish forms can also refer to the future: the simple present can describe a scheduled or confidently presented event, and the simple future has its own uses. The goal here is to build and interpret one useful construction accurately, not to replace every possible future message with it or to claim that two future expressions can never overlap in meaning.
Mañana vamos a preparar una fiesta.
Tomorrow we are going to prepare a party.
The intended subject is we, so vamos marks the group’s plan. The time phrase places the action tomorrow without changing the person ending.
Creo que va a llover.
I think it is going to rain.
The weather event uses impersonal singular grammar, giving va a llover. The construction expresses a prediction rather than a deliberate decision by a person.
Ask when and where the plan will happen
Once a plan is established, the listener may need a time or place. Cuándo asks when the event will occur, and dónde can ask its location. Keep the question word connected to the exact missing information. A reply naming a library cannot answer when, and a reply naming Tuesday cannot answer where. With a movement verb, dónde and adónde or a dónde can also ask about destination, so the presence or absence of a separate a is not always a right versus wrong contrast. The questions here supply an answer or a clear context to narrow the choice. The complete future construction remains inside the question: question words do not license dropping its preposition or conjugating its infinitive. This lets you extend a simple plan into a practical exchange about scheduling without learning an unrelated sentence pattern for every new detail.
¿Cuándo vas a estudiar? Después de comer.
When are you going to study? After eating.
The reply provides a time relationship, so cuándo asks the needed information. The planned activity still appears as vas a estudiar.
¿Dónde vamos a comer? En casa.
Where are we going to eat? At home.
The missing information is the location of the meal. Dónde fits the answer, while vamos includes the speaker in the planned activity.
Try the reasoning with less help
Build a sentence with this meaning: When are you going to study? After eating. Before looking at the answer, identify which information controls the grammatical choice.
- First, identify the message: When are you going to study? After eating. Keep that message fixed while comparing forms. A sentence can be grammatical yet communicate something different, so meaning is part of the decision.
- The reply provides a time relationship, so cuándo asks the needed information. The planned activity still appears as vas a estudiar.
- Now read the complete sentence, ¿Cuándo vas a estudiar? Después de comer. Check the words surrounding your choice as well as the choice itself. Explain what would change if the speaker, number, or intended message changed. Then cover this example and reconstruct the sentence from the English cue.

Place short pronouns in a permitted position
When the planned action has a short object or reflexive pronoun, common constructions allow the pronoun before the finite form or attached to the infinitive. Compare Lo voy a comprar with Voy a comprarlo, or Me voy a levantar with Voy a levantarme. These are alternatives for the same basic meaning, so a quiz should not reject one merely because the other was taught first. What you should avoid is inserting a separate pronoun between a and the infinitive. With negation, place no before the complete initial grouping, as in No me voy a levantar temprano. Match a reflexive pronoun to the subject of the action; changing from I to we changes me to nos. Practice one placement confidently, then recognize the alternative. Both comprehension and production benefit when a flexible pattern is taught with its real limits.
Voy a levantarme temprano.
I am going to get up early, with the reflexive pronoun attached to the infinitive.
The infinitive stays intact and takes the speaker’s reflexive pronoun at its end. The alternative Me voy a levantar is also valid, but this prompt requests attachment.
Lo voy a comprar mañana.
I am going to buy it tomorrow, placing lo before the finite verb.
Lo precedes the finite speaker form voy. The alternative with attachment is also possible, but this prompt explicitly practices the position before the finite verb.

Notice the difference
Common mistakes
Keep the connecting preposition
Instead ofVoy estudiar mañana.
For this meaningVoy a estudiar mañana.
The future construction requires a between the finite form of ir and the infinitive. Its short unstressed pronunciation does not make it optional in standard writing.
Only the first verb is finite
Instead ofVamos a comemos aquí.
For this meaningVamos a comer aquí.
The form vamos already identifies the group. The action that follows a must stay in the infinitive, so use comer rather than the finite form comemos.
Do not split the infinitive connection
Instead ofVoy a me levantar.
For this meaningVoy a levantarme.
Attach the reflexive pronoun to the infinitive in this position. The alternative Me voy a levantar is also valid. A separate me between a and levantar does not follow either permitted pattern.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
Write a plan saying that you and your friends are going to cook tomorrow, but are not going to eat at home.
Compare with a model
Mañana vamos a cocinar, pero no vamos a comer en casa.
Tomorrow we are going to cook, but we are not going to eat at home.
Both clauses include the speaker in their subject and therefore use vamos. Each planned action remains an infinitive after a. The second clause adds no before the finite verb. The location phrase belongs to the eating plan and does not change the form of the first clause.
- Did you preserve the requested meaning?
- Does the form match the person or noun in your message?
- Can you explain your choice before looking at the model?
Your turn 2
Say that you are going to get up early, writing both permitted positions of the reflexive pronoun.
Compare with a model
Voy a levantarme temprano. Me voy a levantar temprano.
I am going to get up early. I am going to get up early.
Both versions keep voy a and the infinitive together as the planning construction. One attaches me to the infinitive; the other places it before voy. Neither places a separate pronoun immediately after a. The speaker remains the person who gets up in both sentences.
- Did you preserve the requested meaning?
- Does the form match the person or noun in your message?
- Can you explain your choice before looking at the model?

Question 1
Complete the sentence for this meaning: I am going to study this afternoon.
Yo ___ a estudiar esta tarde.
- voy
- va
Check the answer
Answer: voy
voy: The subject is the speaker, so the finite form is voy. The following a estudiar names the planned activity without taking another person ending.
va: Va belongs with third person singular grammar or usted, not the explicit speaker subject yo.
Question 2
Complete the sentence for this meaning: My friends are going to cook.
Mis amigos ___ a cocinar.
- vamos
- van
Check the answer
Answer: van
vamos: Vamos includes the speaker in the subject. The sentence identifies the friends as the group, so the requested form is van.
van: The plural subject means they, requiring van. The planned action stays in the infinitive cocinar even though more than one person will perform it.
Question 3
Complete the sentence for this meaning: We are going to eat soon.
Nosotros vamos ___ comer pronto.
- a
- de
Check the answer
Answer: a
a: The preposition a connects the finite form of ir to the infinitive. It remains required even though it is a short unstressed word in ordinary speech.
de: De does not form this future construction. The required connection is ir a followed by the infinitive.
Question 4
Complete the sentence for this meaning: Ana is going to make dinner.
Ana va a ___ la cena.
- hace
- hacer
Check the answer
Answer: hacer
hace: Hace is a finite present form. It cannot replace the infinitive after va a in the intended construction.
hacer: Only va is finite. The action verb remains hacer, so its irregular present form is not needed in this position.
Question 5
Complete the sentence for this meaning: I am not going to go out today.
Yo no ___ a salir hoy.
- voy
- ir
Check the answer
Answer: voy
voy: The negative marker precedes the finite speaker form voy. The infinitive salir names the denied plan and does not lose its ordinary dictionary form.
ir: The infinitive ir does not identify the speaker in this complete statement. Negation still requires a finite verb form.
Question 6
Complete the sentence for this meaning: Are you going to travel tomorrow, using usted?
¿Usted ___ a viajar mañana?
- vas
- va
Check the answer
Answer: va
vas: Vas is the familiar singular form used with tú in this lesson. It does not match the explicitly requested usted pattern.
va: The listener is addressed with singular usted, so the finite form is va. Question punctuation changes the communicative purpose without changing the required person agreement.
Question 7
Complete the sentence for this meaning: I am going to go to the museum.
Voy a ___ al museo.
- ir
- voy
Check the answer
Answer: ir
ir: The first voy builds the future construction, while the infinitive ir names the planned movement. Repeating the same verb family in these two roles is grammatical.
voy: The second verb belongs after a as an infinitive. Another finite voy would break the construction.
Question 8
Complete the sentence for this meaning: We are going to visit Ana.
Vamos a ___ a Ana.
- visitamos
- visitar
Check the answer
Answer: visitar
visitamos: Visitamos is finite. This position requires the infinitive that names the planned action.
visitar: The plan uses an infinitive after vamos a. The later a before Ana belongs to a separate personal object pattern and does not replace the earlier connector.
Question 9
Complete the sentence for this meaning: Tomorrow we are going to prepare a party.
Mañana ___ a preparar una fiesta.
- vamos
- van
Check the answer
Answer: vamos
vamos: The intended subject is we, so vamos marks the group’s plan. The time phrase places the action tomorrow without changing the person ending.
van: Van refers to they or a group addressed with ustedes. It does not express the we plan specified here.
Question 10
Complete the sentence for this meaning: I think it is going to rain.
Creo que ___ a llover.
- van
- va
Check the answer
Answer: va
van: The impersonal weather construction does not have a plural subject. Use the singular auxiliary form for this prediction.
va: The weather event uses impersonal singular grammar, giving va a llover. The construction expresses a prediction rather than a deliberate decision by a person.
Question 11
Complete the sentence for this meaning: When are you going to study? After eating.
¿___ vas a estudiar? Después de comer.
- Cuándo
- Dónde
Check the answer
Answer: Cuándo
Cuándo: The reply provides a time relationship, so cuándo asks the needed information. The planned activity still appears as vas a estudiar.
Dónde: Dónde would request a place. The supplied answer tells when the studying will occur.
Question 12
Complete the sentence for this meaning: Where are we going to eat? At home.
¿___ vamos a comer? En casa.
- Cuándo
- Dónde
Check the answer
Answer: Dónde
Cuándo: Cuándo asks about time. The answer given here identifies a place instead.
Dónde: The missing information is the location of the meal. Dónde fits the answer, while vamos includes the speaker in the planned activity.
Question 13
Complete the sentence for this meaning: I am going to get up early, with the reflexive pronoun attached to the infinitive.
Voy a ___ temprano.
- levantarme
- me levantar
Check the answer
Answer: levantarme
levantarme: The infinitive stays intact and takes the speaker’s reflexive pronoun at its end. The alternative Me voy a levantar is also valid, but this prompt requests attachment.
me levantar: A separate pronoun cannot occupy this gap after a. Attach it to the infinitive or move it before the finite verb.
Question 14
Complete the sentence for this meaning: I am going to buy it tomorrow, placing lo before the finite verb.
___ a comprar mañana.
- Voy lo
- Lo voy
Check the answer
Answer: Lo voy
Voy lo: This reverses the required relationship between the separate pronoun and the finite verb. Use lo voy in the requested position.
Lo voy: Lo precedes the finite speaker form voy. The alternative with attachment is also possible, but this prompt explicitly practices the position before the finite verb.
