Irregular Simple Future Forms

Quick Answer

There are two ways to form the future tense in Spanish: the informal future (ir + a + infinitive) and the simple future (el futuro simple).

The simple future has both regular forms and irregular forms. Let's learn about the irregular forms now!

The simple future has relatively few irregular verbs, and they fall into three distinct categories:

  • those that drop the e or i from the infinitive ending and add a d
  • those that simply drop the e or i from the infinitive ending
  • those that don't follow any predictable pattern and must simply be memorized

Forms that Drop the e or i from the Infinitive Ending and Add a d

Only -er and -ir verbs fall into this category. To form the future with verbs in this category, simply remove the e or i from the infinitive ending, add a d, then add the simple future endings.

Irregular stems

The verbs decir (to say) and hacer (to make/to do) have irregular stems that must be memorized. Verbs that have either of these two verbs as their root, such as predecir (to predict) and rehacer (to redo), follow the same conjugation patters as decir and hacer in the simple future.

Conjugation Examples: Decir and Hacer
