Future Usage

What This Level Solves

You now know two future forms:

• Futuro Simple
• Ir + a + Infinitive

This level explains when to use each one.

Core Difference

1. Planned Actions (Ir + a)

Use for intention or plan.

• Voy a estudiar mañana.
• Vamos a cambiar el sistema.

2. Predictions (Futuro Simple)

Use for assumptions about the future.

• Lloverá mañana.
• Llegarán tarde.

3. Probability (Futuro Simple)

Used to express uncertainty about the present.

• Estará en casa. = He/She is probably at home
• Tendrán dinero. = They probably have money

4. Immediate Decisions

• Voy a llamar ahora.

5. Neutral Future

Sometimes both are possible:

• Mañana trabajo
• Mañana voy a trabajar
• Mañana trabajaré

Each adds nuance.

Key Insight

Future in Spanish is about intention vs assumption, not just time.
