Spanish Si Clauses

The si clauses, also known as conditional sentences or conditionals, express a condition that needs to be met so something else occurs.

How to Form the Spanish Conditionals?

The si clauses consist of two parts:

  • A si clause that expresses a condition.
  • A main clause which tells us what will happen if the condition is met.

The order of the sentences is unimportant. Thus, the si clause can go before or after the main clause. If the main clause precedes the si clause, you don´t need the comma.

However, remember that si belongs to the clause that expresses the condition.

  • Si tuviera tiempo, viajaría más. → If I had time, I would travel more.
  • Viajaría más si tuviera tiempo. → I would travel more if I had time.

When do I Use Subjunctive with a Si Clause in Spanish?

This is a common question students of Spanish as a second language have.

Knowing what verb tense to use in each type of si clauses can be hard. Consequently, you end up mixing up the tenses.

Here is a tip:

  • Si is followed by present indicative when the possibility of the condition is likely or real.
  • Si is followed by subjunctive when the condition is unlikely, impossible or unreal.

Types of Spanish Si Clauses

We can classify the si clauses in three types according on how likely the condition is:

  • Type 1: Possible/real conditions.
  • Type2: Unlikely conditions.
  • Type 3: Impossible/unreal conditions.
