When do I use the conditional in Spanish?

Use the conditional for: hypothetical statements (would do), polite requests (¿podrías?), past probability (sería el cartero), reported past speech (dijo que vendría), and hypothetical si-clauses (si tuviera, iría).

What's the difference between the future and the conditional?

Future = will (definite future) or present probability (¿quién será?). Conditional = would (hypothetical) or past probability (sería el cartero). Same stem; different endings.

How do I make a polite request in Spanish?

Use the conditional: ¿Podrías...? (Could you...?), ¿Serías tan amable de...? (Would you be so kind as to...?), Me gustaría... (I would like...). Conditional is the most polite form for requests.

How do I form hypothetical si-clauses?

Si + past subjunctive + conditional. Si tuviera tiempo, iría = If I had time, I would go. Si fuera rico, compraría una casa = If I were rich, I'd buy a house. The past subjunctive is in the si-clause; the conditional is in the result clause.

How can I master when to use the conditional?

Memorize the regular endings (-ía, -ías, -ía, -íamos, -íais, -ían) and the 12 irregular stems (same as future). Practice politeness contexts (¿podrías?) and hypothetical contexts (si tuviera...). Parrot's videos surface natural conditional usage.

When to Use the Conditional in Spanish: The Complete Guide

Written by Sofia Ramirez, Lead Spanish Curriculum Editor · Reviewed May 2026

Use the conditional (hablaría, comería) for hypothetical statements (would do), polite requests (would you...?), past probability (must have), reported speech in past, and si-clauses (si tuviera tiempo, iría). Same stem as future, different endings (-ía, -ías, -ía).

Me gustaría un café.

I would like a coffee.

What it is

Use the Spanish conditional tense (hablaría, comería, viviría) for hypothetical statements, polite requests, past probability, and reported speech. Equivalent to English would + verb.

In Me gustaría un café (I would like a coffee), gustaría is the conditional of gustar, expressing a polite preference.

How to spot it

Look for hypothetical contexts (si...), polite questions (¿podrías...?), past probability (sería el cartero), and reported speech (dijo que vendría).

Me gustaría viajar más. — I would like to travel more.
¿Podrías ayudarme? — Could you help me?
Dijo que vendría. — He said he would come.

Conditional is one of the most polite ways to make requests in Spanish. ¿Podrías? is more polite than ¿puedes?

Conditional Tense Formation and Use

Structure: Infinitive + Endings

Conditional endings (-ía, -ías, -ía, -íamos, -íais, -ían) attach to the infinitive. Hablaría, comerías, viviría. All forms carry an accent on the í.

hablar + ía = hablaría.

Regular pattern.

Infinitive + conditional endings.

Same Stem as Future

The conditional uses the SAME stem as the future. Regular verbs: stem = infinitive. Irregular verbs: same 12 modified stems (habr-, tendr-, har-, dir-, etc.).

Future: tendré. Conditional: tendría.

Same stem, different endings.

Same 12 irregular stems.

Si-Clauses with Conditional

Hypothetical si-clauses: si + past subjunctive + conditional. Si tuviera tiempo, iría (If I had time, I would go). Si supiera, te diría (If I knew, I'd tell you).

Si pudiera, viajaría.

If I could, I would travel.

Si + past subjunctive + conditional.

Conditional Perfect: Habría + Past Participle

Conditional of haber + past participle = conditional perfect. Habría comido (would have eaten). Used for hypothetical past actions.

Si hubiera estudiado, habría aprobado.

If I had studied, I would have passed.

Habría + past participle.

Common Mistakes with When to Use the Conditional in Spanish

Incorrect: Hablaria mañana. — I would speak tomorrow.

Correct: Hablaría mañana. — I would speak tomorrow.

All conditional forms carry an accent on the í: hablaría, hablarías, hablaríamos. Without the accent, the word is misspelled.

Incorrect: Si tengo tiempo, iría. (mixed tenses) — If I have time, I'll go. / If I had time, I'd go.

Correct: Si tengo tiempo, iré. / Si tuviera tiempo, iría. — If I have time, I'll go. / If I had time, I'd go.

Real conditional: si + present + future (Si tengo, iré). Hypothetical conditional: si + past subjunctive + conditional (Si tuviera, iría). Don't mix.

Incorrect: Me gustara más café. (subjunctive instead of conditional) — I would like more coffee.

Correct: Me gustaría más café. — I would like more coffee.

For a polite I would like, use the conditional gustaría, not the imperfect subjunctive gustara. Conditional = polite preference.

Conditional in Si-Clauses

Hypothetical Conditional Sentences

For hypothetical / contrary-to-fact situations: si + past subjunctive + conditional. Si tuviera dinero, viajaría = If I had money, I would travel.

Si pudiera, te ayudaría.: If I could, I'd help you.
Si fuera rico, compraría una casa.: If I were rich, I'd buy a house.
Si supiera la respuesta, te la diría.: If I knew the answer, I'd tell you.

Real conditional uses si + present + future. Hypothetical uses si + past subjunctive + conditional. Choose based on whether the situation is likely or hypothetical.
