Frame
ir (present) + a + infinitive
Spanish 101 · Grammar
Ir a + infinitive
This pattern is your default for “going to do” something — not to be confused with present progressive.
The rule
Conjugate ir, then a, then the infinitive: Voy a estudiar, Vamos a comer, Van a llegar tarde.
Questions keep the same frame: ¿Vas a venir con nosotros?
Reflexives attach to the infinitive or precede the conjugated verb: Me voy a dormir / Voy a dormirme (both possible with different nuance/register).
Never put a conjugated verb after a in this pattern: *Voy a como* is ungrammatical.
¿Qué van a hacer este fin de semana?What are you all going to do this weekend?
Voy a llamarte después de clase.I am going to call you after class.

How do I know if a verb is stem-changing?
Your vocabulary list or textbook marks e→ie, o→ue, e→i, etc. Changes usually appear in the boot shape of present indicative (not nosotros/nosotras in many -ar/-er verbs). There is no single rule from the infinitive alone—you learn per verb or family.
Why is the yo form sometimes irregular while tú looks regular?
Verbs like hacer (hago) or salir (salgo) add supporting letters or change stems only for yo in the present. The rest of the singular/plural pattern may follow the regular endings. Drill yo alongside ellos because those forms are the most exam-visible.
What is ir a + infinitive?
It is a common periphrasis for near future: Voy a estudiar = I am going to study. Conjugate ir, keep a, and add the unchanged infinitive. It is not the same as the simple future tense learned later.
When can I use the present progressive?
Estar + gerund stresses that an action is in progress right now: Estoy leyendo. Spanish does not use it for stative verbs the way English might (*Estoy queriendo is odd). Follow your book’s list of verbs that prefer simple present.
How do reflexive pronouns line up?
They match the subject: me, te, se, nos, os, se. They usually come before a conjugated verb or attach to an infinitive/command: Me lavo las manos; Voy a lavarme. Placement rules parallel other object pronouns.
