Spanish conditional tense - Forms and usage1 votes. 4.5 / 5

In Spanish, the conditional tense is used to talk about probability, possibility, or hypothetical situation. It is usually translated as would, could, probably, or must have in English. In this lesson, we will learn about different forms of conditional tense in Spanish and verb conjugation in the conditional.

Spanish conditional tense

The conditional tense form is much like the Spanish future simple tense. 

Regular conditional forms

In order to form the conditional tense with regular verbs, you just need to add the conditional endings to the end of the infinitive.

To conjugate regular -ar, -er, and -ir verbs in the conditional, simply add one of the following endings to the infinitive:

SubjectEnding
yo -ía
tú -ías
usted, él, ella -ía
nosotros -íamos
vosotros -íais
ustedes, ellos, ellas -ían

For example:

El alumno dijo que estudiaría una hora más - The student said that he would study one more hour

Compraría esa camisa - I would buy that shirt

Si fuera rico, me gustaría viajar por todo el mundo - If I were rich, I would travel all over the world

Estaríamos ocupados cuando llamaste - We were probably busy when you called

Irregular conditional forms

Any stems that are irregular in the Spanish future simple tense are also irregular in the conditional tense.

Note: Both regular and irregular verbs have the same set of endings, however, stems of the irregular change. And they change in the same way as they do in the future tense.

Irregular verbs fall into three categories:

1. Verbs with the last vowel in the infinitive is replace with -d 

 Simply replace the e or i with -d then add the conditional endings. Verbs in this category include: poner, valer, salir, venir

The table below shows tener conjugation in the conditional:

SubjectTener (to have) conjugation
yo tendría
tú tendrías
usted, él, ella tendría
nosotros tendríamos
vosotros tendríais
ustedes, ellos, ellas tendrían

For example:

Usted tendría una casa nueva - You would have a new house

2. Verbs with the last vowel in the infinitive is removed.

Verbs that fall into this category include: poder, caber, haber, querer, saber

In order to form the stem of verbs of this category, simply remove the vowel from the infinitive ending then add the conditional endings. The table below shows the conditional conjugation of the verb poder:

SubjectTener conjugation
yo podría
tú podrías
usted, él, ella podría
nosotros podríamos
vosotros podríais
ustedes, ellos, ellas podrían

For example:

¿Podrías pasar el agua? - Would you pass the water?

3. Irregular stems

Decir (to say) and hacer (to do/ to make) have different stem changes. Check out the table below to see the conditional conjugation of these two verbs:
