Quick answer
Voy a comer. · Comeré.
Two futures. The first is what people actually say; the second is shorter in writing and used for predictions.
The everyday future: ir a
Voy a llamarte.I am going to call you.
¿Vas a venir?Are you coming?
Vamos a ver.We will see.
The simple future
One set of endings for all three verb groups, stuck onto the whole infinitive.
| yo | hablaré |
| tú | hablarás |
| él/ella | hablará |
| nosotros | hablaremos |
| vosotros | hablaréis |
| ellos | hablarán |
The future of guessing
Spanish uses the future tense for present-day guesses — a use English does not have.
¿Dónde está? — Estará en casa.Where is he? — He is probably at home.
Serán las tres.It must be about three o\u2019clock.
Memory trick
Plans take ir a. Predictions and guesses take the future tense.
Typical mistakes
Voy comer.
Voy a comer.
ir needs its a before the infinitive.
Mañana comeré con mi madre (in speech)
Mañana voy a comer con mi madre
Both are correct, but the second is what people say.
