Indefinite future tense: uses and rules

Indefinite future tense: uses and rules

Although the future is unpredictable, we talk about it all the time. We predict it; we planned it

And to talk about it, we need future tenses. And to talk about something (an action) that you predict, promise, or plan in the future at a certain time, we need the indefinite future tense, which is also commonly known as the simple future tense.

When to use the Future indefinite tense?

We use the future indefinite tense to talk about something (an action) that happens at a certain time in the future. The word that refers to the future tense is called a future tense marker.

Algunos marcadores de tiempo futuros: tomorrow, next day, next week, next month, next quarter, next year, next decade…

We use“will + V1“to form sentences in the future indefinite.

Future indefinite tense examples:

  • I will call you tomorrow.
  • My friend Monu will get married next month.
  • The players will not show up today.
  • She will cook in the evening.
  • I will be there in 50 minutes.
  • Will you take the class tomorrow?
  • We will go to Goa next month.
  • She will not come to the party tonight.
  • You will be a successful person.

TIP: if the speaker knows the moment in which the action occurs in the future or already understands it, we do not mention it in the sentence.

  • You will be very rich.
    (This will happen in the future sometime; I just don’t know when.)
  • Yes, I will join you.
    (Here, the time of the action is already known to both the speaker and the listener/reader.)

WILL vs SHALL in the future indefinite tense

The use of SHAL in modern English has become archaic. WILL is used with all kinds of pronouns and nouns.

Traditionally, SHALL was used with first-person pronouns (ME AND WE), and WILL was used with second-person (YOU) and third-person pronouns (HIM, SHE, HIM, and THEM).


  • I shall leave now.
  • We shall order the food.
  • He will not come back home today.
  • She will get married this week.
  • He will join us in the evening.
  • They will take care of you.

SHALL, sin embargo, todavía se usa en documentos burocráticos, generalmente escritos por los abogados.
