si + Imperfect Subjunctive + Conditional

Unreal Si Clauses (Present)

Level 4

Use si + imperfect subjunctive in the condition clause (if-clause) and the conditional tense in the result clause to talk about hypothetical or unreal present/future situations.

How It Works

When describing hypothetical present situations or unlikely future scenarios, Spanish pairs two main verb forms:

1. The Condition Clause (Si clause):
Starts with si (if) followed by a verb in the imperfect subjunctive (or -iera/-iese endings). Note that si is never directly followed by the present subjunctive or the conditional tense in standard Spanish.

2. The Result Clause:
Uses the conditional tense to express what would take place if the hypothetical condition were met.

Clause Order:
The order of clauses can be reversed without changing the core meaning:
• Si tuviera tiempo, iría al cine. (If I had time, I would go to the movies.)
• Iría al cine si tuviera tiempo. (I would go to the movies if I had time.)

Key Usage Distinction:
Unlike real conditional sentences (si + present indicative), this structure signals that the condition is currently false, unlikely, or purely imaginary.

Examples (4)

  1. Si tuviera más dinero, viajaría por todo el mundo.

    If I had more money, I would travel around the whole world.

    Word by Word: If I had more money, I would travel through all the world.

    The 'si' clause uses the imperfect subjunctive 'tuviera' (contrary to present reality), and the main clause uses the conditional 'viajaría'.

  2. Si vivieras más cerca, te visitaría cada fin de semana.

    If you lived closer, I would visit you every weekend.

    Word by Word: If you lived more close, you I would visit each end of week.

    'Vivieras' sets up the hypothetical condition, while 'visitaría' expresses the imagined consequence.

  3. Si ella supiera la respuesta, nos la diría ahora mismo.

    If she knew the answer, she would tell it to us right now.

    Word by Word: If she knew the answer, to us it she would tell right now.

    Highlights a present unreal situation: she doesn't know the answer right now, so she cannot tell us.

  4. Haríamos una fiesta si el tiempo estuviera mejor.

    We would have a party if the weather were better.

    Word by Word: We would make a party if the weather were better.

    Demonstrates clause reversal: the result clause ('Haríamos...') comes before the 'si' clause ('si... estuviera').

Common Mistakes

  • Using the conditional tense directly after 'si'

    Si tendría tiempo, iría contigo.
    Si tuviera tiempo, iría contigo.

    In standard Spanish, 'si' (meaning 'if') should never be directly followed by the conditional tense. Always use the imperfect subjunctive after 'si' in unreal present conditional clauses.

  • Using the present subjunctive after 'si'

    Si tenga más dinero, compraría un coche.
    Si tuviera más dinero, compraría un coche.

    'Si' is never followed directly by the present subjunctive in conditional clauses. For unreal or hypothetical situations, use the imperfect subjunctive instead.

Learn This First

To learn unreal 'si' clauses, you must first be able to conjugate verbs in both the imperfect subjunctive and the conditional tense. Additionally, familiarity with the basic structure of 'si' clauses (conditions and results) from real-world scenarios is essential.
