The Futur Simple — The “SI” Rule

Objective: Learn how to build complex sentences with conditions.

The “si” rule is one of the most common ways to connect actions and results in French.


The Golden Rule

Si + Présent → Futur Simple

This means:

  • Use si + present tense for the condition
  • Use futur simple for the result

Example:

  • Si j’ai de l’argent, j’achèterai une voiture → If I have money, I will buy a car
  • Si tu viens, nous irons au cinéma → If you come, we will go to the cinema
  • Si elle étudie, elle réussira → If she studies, she will succeed

This is one of the most common structures in everyday French conversation.

Key Takeaways

  • “Si + present” = condition
  • Futur simple = result of the condition
  • Structure is predictable and used all the time in spoken and written French
  • Combine with any futur simple verb you know — regular or irregular
  • Practice this rule to make your sentences more natural and fluent
