Simple Conditional in Spanish

Overview

The conditional tense (condicional simple) in Spanish expresses what would happen under certain circumstances, what you would like, or what someone would do. It is the tense of politeness, hypotheticals, and reported future-in-the-past. If the future tense answers "What will happen?", the conditional answers "What would happen?"

At the B1 level, learning the conditional greatly expands your ability to express nuance. You can make polite requests (¿Podrías ayudarme?), talk about hypothetical situations (Viajaría si tuviera dinero), and report what someone said they would do (Dijo que vendría).

The formation is delightfully simple: take the full infinitive (just like the future tense) and add the conditional endings. These endings are actually the imperfect tense endings of the verb haber. And the irregular stems? They are exactly the same ones you learned for the future tense.

How It Works

Regular Formation

Take the full infinitive and add the conditional endings:

Person	Ending	Hablar	Comer	Vivir
yo	-ía	hablaría	comería	viviría
tú	-ías	hablarías	comerías	vivirías
él/ella/usted	-ía	hablaría	comería	viviría
nosotros/as	-íamos	hablaríamos	comeríamos	viviríamos
vosotros/as	-íais	hablaríais	comeríais	viviríais
ellos/ellas/ustedes	-ían	hablarían	comerían	vivirían

Note: All forms carry an accent on the -í-.

Common Mistakes

Confusing conditional and imperfect endings

• Wrong: Yo hablaba si pudiera. (imperfect instead of conditional)
• Right: Yo hablaría si pudiera.
• Why: While the conditional endings (-ía, -ías, -ía...) look like the imperfect of -er/-ir verbs, they attach to the full infinitive, not the stem. Comía (I used to eat) vs. comería (I would eat).

Using the wrong stem for irregulars

• Wrong: Yo haciería eso.
• Right: Yo haría eso.
• Why: The irregular stems for the conditional are the same as the future tense. The verb hacer uses the stem har-, not hacier-.

Using conditional in the si-clause

• Wrong: Si tendría dinero, viajaría.
• Right: Si tuviera dinero, viajaría.
• Why: In conditional sentences, the si-clause takes the imperfect subjunctive, never the conditional. The conditional goes in the result clause.

Forgetting accent marks

• Wrong: Yo hablaria contigo.
• Right: Yo hablaría contigo.
• Why: Every conditional form has a written accent on the í. This distinguishes it from other tenses and is not optional.

Usage Notes

The conditional is widely used across all varieties of Spanish, though some nuances differ by region. In formal situations, the conditional is the go-to choice for politeness: ¿Podría hablar con usted? sounds more refined than ¿Puedo hablar con usted?

In colloquial speech, particularly in parts of Latin America, you may hear the imperfect used where the conditional is standard: Si tenía dinero, viajaba instead of Si tuviera dinero, viajaría. While understood everywhere, this is considered informal.

The "probability in the past" use (Serían las tres -- "It was probably around three") parallels the future tense's use for present probability. This is a sophisticated feature worth practicing.

In reported speech, the conditional consistently replaces the future: "Vendré" (I will come) becomes Dijo que vendría (He said he would come).

Practice Tips

• Since the conditional shares its irregular stems with the future tense, practice them as pairs: tendré/tendría, haré/haría, podré/podría. Mastering one tense gives you the other for free.
• Role-play polite scenarios: ordering at a restaurant (Me gustaría..., ¿Podría traerme...?), asking for help (¿Sería posible...?), giving advice (Yo que tú, haría...).
• Practice converting direct speech to reported speech: "Iré mañana" becomes Dijo que iría al día siguiente.
