What Are Si Clauses in Spanish?

Si clauses are conditional sentences that express a condition and its possible result. They are composed of two parts:

• Si clause (protasis): The condition, introduced by “si” meaning “if.”
• Main clause (apodosis): The result or consequence of that condition.

For example: Si estudias, aprobarás el examen. (If you study, you will pass the exam.)

Understanding how to construct and use si clauses is crucial for communicating possibilities, hypothetical situations, or general truths in Spanish.

Types of Si Clauses Spanish

There are three main types of si clauses in Spanish, each corresponding to different levels of likelihood or reality:

1. Real Conditional (Possible Condition)

This type describes conditions that are possible or likely to happen. The structure is:

• Si clause: Present indicative
• Main clause: Present indicative, future indicative, or imperative

Example:

• Si tienes tiempo, ven a la fiesta. (If you have time, come to the party.)
• Si estudias, aprobarás el examen. (If you study, you will pass the exam.)

2. Unreal Present Conditional (Hypothetical or Contrary to Present Fact)

This conditional expresses situations that are unlikely or contrary to current reality. The structure is:

• Si clause: Imperfect subjunctive
• Main clause: Conditional tense

Example:

• Si tuviera dinero, viajaría por el mundo. (If I had money, I would travel around the world.)
• Si fuera más alto, jugaría baloncesto. (If I were taller, I would play basketball.)

3. Unreal Past Conditional (Contrary to Past Fact)

This type refers to hypothetical situations in the past that did not happen. The structure is:

• Si clause: Past perfect subjunctive (pluscuamperfecto de subjuntivo)
• Main clause: Conditional perfect (condicional perfecto)

Example:

• Si hubieras estudiado, habrías aprobado el examen. (If you had studied, you would have passed the exam.)
• Si me hubieran invitado, habría ido a la fiesta. (If they had invited me, I would have gone to the party.)
