Just as in English, the future in Spanish situates events that happen after the moment of utterance. Following are the primary uses of the future tense:

-To describe events that will happen in the future.

La próxima semana nos iremos a la playa.

-To express an order or command.

Desde hoy estudiarás todos los días.

– To alert or warn.

Repetirás el año si no estudias.

-To utter threats.

Me las pagarás.

 -To asume or speculate.

Creo que llegará en media hora.
