Irregular future verbs in Spanish stem from common verbs by altering the root before adding the regular future endings (-é, -ás, -á, -emos, -éis, -án). Irregularities always appear in the stem, but the endings remain the same as in regular future conjugations.
Here are the nine most common irregular verbs in the future tense, along with their irregular stems, meanings, and example sentences.
Key Irregular Stems and Examples
| Verb | Irregular Stem | Meaning | Example (Yo) | Example Meaning |
|---|---|---|---|---|
| decir | dir- | to say/tell | diré | I will say |
| hacer | har- | to do/make | haré | I will do/make |
| poder | podr- | can/to be able to | podré | I will be able to |
| poner | pondr- | to put/place | pondré | I will put |
| salir | saldr- | to leave/go out | saldré | I will leave |
| tener | tendr- | to have | tendré | I will have |
| venir | vendr- | to come | vendré | I will come |
| querrer | querr- | to want/love | querré | I will want |
| saber | sabr- | to know | sabré | I will know |
Explanation of Patterns
- The irregularity is always in the stem (middle part of the verb) before the ending is added.
- Endings are the standard future endings:
| Pronoun | -é | -ás | -á | -emos | -éis | -án |
|---|---|---|---|---|---|---|
| yo | diré | dirás | dirá | diremos | diréis | dirán |
- Use these verbs to express what will happen or what you intend to do in the future.
Does the subject pronoun affect the stem change in irregular future verbs?
No, the stem change is the same for all subjects; only the endings change.
The irregular stem appears once and is used for all subject pronouns, with only the standard endings varying per subject.
Example Conjugations
| Verb | Yo | Tú | Él/Ella/Usted | Nosotros | Vosotros | Ellos/Ellas/Ustedes |
|---|---|---|---|---|---|---|
| decir | diré | dirás | dirá | diremos | diréis | dirán |
| hacer | haré | harás | hará | haremos | haréis | harán |
| poder | podré | podrás | podrá | podremos | podréis | podrán |
Complete the future tense for 'Hacer' (to do/make) with 'vosotros': 'Vosotros ___ (hacer) el proyecto.'
haréis
'Hacer' changes its stem to 'har-'. Adding the future ending for 'vosotros' (-éis) gives 'haréis.'
Usage Tips
- Use the future tense to speak about things that will happen or that you intend to happen.
- Stem changes appear only once in the verb, before the endings are added.
- All forms use the same set of endings; only the stem changes.
- Don’t add extra letters—just use the irregular root and then the regular endings.
- The endings -é, -ás, -á, -emos, -éis, and -án always remain intact.
