emploi des structures hypothétiques grammar in French

What this grammar point covers

Hypothetical structures in French are used to talk about situations that are imaginary, unreal, or possible only under certain conditions.

Use these structures in French to express possibilities, give advice, imagine alternative outcomes, or talk about things that did not happen.

Si tu viens, nous irons au cinéma.

English: If you come, we will go to the cinema.

Si j'avais de l'argent, j'achèterais une voiture.

English: If I had money, I would buy a car.

Si elle avait su, elle serait venue.

English: If she had known, she would have come.

Si nous avions étudié, nous aurions réussi l'examen.

English: If we had studied, we would have passed the exam.

Never use 'si' with the future tense right after it (e.g., not 'si tu viendras').
Pay attention to the correct tense combination: present with future, imparfait with conditional, plus-que-parfait with past conditional.
Do not use 'conditionnel' immediately after 'si'.
