Did you see what Maura did there? Se used conditional tense Spanish, which is the equivalent of if-sentences in Spanish that always start with “si”.

In this lesson, you’ll learn all you need to know about conditionals in Spanish; the most challenging part is getting the verb conjugations right.

What is conditional tense Spanish?

The conditional tense in Spanish is used to express hypothetical situations, polite requests, past probabilities, and future actions from a past perspective.

It’s formed by adding specific endings to the infinitive form of the verb, similar to the future tense but with different endings.

For regular verbs, these endings are:

• -ía
• -ías
• -ía
• -íamos
• -íais and
• -ían.

Some irregular verbs have special stems in the conditional tense, but they follow the same ending pattern.

This tense is essential for expressing the tiniest details in Spanish, particularly when discussing uncertain or imaginary scenarios. Let’s take a look at all the use cases!

1. General aspects of Spanish conditional tense

Conditional sentences present a scenario that is likely to occur if a condition is satisfied. Conditional sentences have two parts:

A subordinated phrase. This one we can recognize because it starts with the word “SI”. Equivalent to the English IF.

This subordinated phrase sets the condition.

The other part is the main clause. This tells you the outcome, the result.

In Spanish there are 3 types of conditional sentences.

Depending on whether the subordinate clause manifests possibility, probability, or unreality. So conditional sentences can be:

• real,
• potential, or
• unreal.

For each kind (real, potential, and unreal) we use different verbal tenses. Let’s start with the real ones.

2. Use the conditional tense in Spanish in real situations

For this case, you conjugate both the subordinate and the main clause in the indicativo (indicative).

For example:

¡Si hay boletos, voy contigo al concerto
(If there are tickets, I’ll go to the concert with you!)

It’s likely/realistic that I would go to the concert if there are tickets. So you say “voy” in indicativo (indicative)

In this case we are using the present indicativo (indicative). In real conditionals, the future indicative is also used.

Si tengo chance, iré al concerto.
(If I get a chance, I will go to the concert.)

Let’s practice with dialogues:

¿Vas a ir a la fiesta?
(Are you going to the party?)

No sé, es que no he llegado a mi casa, pero si me da tiempo, sí voy.
(I don’t know, I haven’t gotten back home, but if I have time, I’ll go.)

It’s likely/realistic that I would have the time. Notice the subjunctive “sí voy”.

¿Vas a ir de vacaciones este año? (Are you going on a vacation this year?)

Si tengo dinero y si me dan vacaciones, iré a Acapulco.
(If I have money and if I get time off from work, I will go to Acapulco.)

¿Vas a ir al festival?
(Are you going to the festival?)

Si consigo boleto.
(If I can get a ticket.)

The next one is a classic phrase brought to you by all Mexican moms whenever they sent us to look for something and we would say that it was nowhere to be found.

Y si yo voy y lo encuentro… ¿qué te hago?
(And what if I go and find it…  what do I do to you?)

Mexicans can be quite controversial when it comes to the way we bring up children. Know more about it in this video:

Let’s continue with more examples:

¿Quieres aceitunas en la pizza?
(Do you want olives in your pizza?)

Sí, pero solo si son aceitunas negras, si no tienen aceitunas negras, no quiero.
(Yes, but only if they are black olives, if they don’t have black olives, I don’t.)

3. Use the Spanish conditional tense in improbable or imaginary sentences

These kind of sentences set an imaginary or hypothetical scenario in the present or the future that is not likely to take place.

The subordinate sentence is conjugated in imperfect subjunctive. Meanwhile, the main sentence is conjugated in conditional.

In any case, to summarize: for conditional sentences like this, you need to use imperfecto de subjuntivo (imperfect subjunctive) for the “if- clause”, and condicional (conditional) for the main clause.

Amiga, ¿me ayudas a pintar mi casa?
(Girlfriend, would you help me paint my house?)

Ay amiga, no tengo tiempo. Te juro que si tuviera tiempo te ayudaría.
(Oh girlfriend, I don’t have time. I swear that if I had the time I would help you.)

Si tuviera tiempo (if I had the time) is the subordinate “if-clause”, in subjuntivo because it’s unlikely to happen. Te ayudaría (I would help you) is the main clause, with the verb conjugated in conditional.

Si te ganaras la lotería, ¿qué harías?
(If you won the lottery, what would you do?)

Si me ganara la lotería, lo primero que haría sería ¡dejar de llevarme contigo!
(If I won the lottery, the first thing I would do would be to stop hanging out with you!)

¿Qué harías si fueras millonaria?
(What would you do if you were a millionaire?)

Si yo fuera millonaria… llevaría a toda mi familia de vacaciones y de compras una vez al año.
(If I were a millionaire… I would take my whole family on a holiday and shopping once a year.)

Attention to all the “ría” ending. ¿Qué harías?, sería, llevaría. That’s key to identifying a conditional sentence.

¿Si pudieras viajar en el tiempo, ¿a dónde irías?
(If you could time-travel, where would you go?)

Si yo pudiera viajar en el tiempo, iría al future.
(If I could travel in time, I would go to the future.)

Si pudieras cenar con cualquier persona, viva o muerta, ¿con quién cenarías?
(If you could have dinner with anyone, dead or alive, with whom would you have dinner?)

Si pudiera cenar con cualquier persona, cenaría con Michael Faraday.
(If I could have dinner with any person, I would have dinner with Michael Faraday.)

Now let’s break into song…

Si te pudiera mentir, te diría que aquí todo va marchando muy bien, pero no es así…
(If I could lie to you, I would tell you that everything is going very well, but it’s not like that…)

Oh this is such a good song.

Se llama “Si Te Pudiera Mentir” de Marco Antonio Solís, pero también hay una versión más moderna de Calibre 50. (It’s called “If I Could Lie to You” by Marco Antonio Solis, but there’s also a more modern version by Calibre 50.)

4. Form the conditional tense in impossible or unreal conditional sentences

Impossible or unreal conditional sentences express a past hypothetical scenario that did not take place.

Attention: In the past.

But instead let’s see some examples:

Si hubiera tenido tiempo, habría ido a la fiesta.
(If I would have had the time, I would have gone to the party.)

“Si hubiera tenido tiempo”, If I would have had the time… BUT I DIDN’T.

So you use the past tense subjunctive. Habría ido a la fiesta (I would have gone to the party), BUT I DIDN’T, so you use the past conditional.

Si hubiera tenido la oportunidad, habría estudiado la universidad en la ciudad de México y no en Cancún.
(If I had had the chance, I would have studied university in Mexico City and not in Cancun.)

Si hubiera sabido que estarías en la ciudad, te habría invitado a salir.
(If I had known that you were going to be in the city, I would have asked you out.)

¿Cómo estuvo el festival?
(How was the festival?)

Increíble.
(Incredible.)

Ajá, pero ¿cómo estuvo? Cuéntame detalles.
(Ok, but how was it? Give me details.)

Bueno, ok, pero si hubieras ido, no te tendría que contar nada.
(Well, ok, but If you had gone, I wouldn’t have to tell you anything.)

Pay attention to that “hubiera”. It’s crucial in the construction of unreal conditional sentences.

Si me hubiera casado con un millonario, otro gallo me cantara.
(If I had married a millionaire, things would be different for me (Lit.: another rooster would sing to me).

Ay amiga, el hubiera no existe.
(Oh girlfriend, “what ifs” doesn’t exist.)

El hubiera no existe. Esta es una frase muy usada en el mundo hispanoparlante. (”What ifs” don’t exist. This phrase is quite used in the Spanish-speaking world.)

We use to say “there is no use in asking what if”.

You’ll hear it a lot!
