# Irregular future stems: tendré, saldré, diré, haré

> id: conjugation.future.irregular-stems · category: conjugation · depth: standard · levels: B1 · review: internally_reviewed

**Summary.** Twelve verbs use a shortened stem before the regular future endings: tener → tendr-, poner → pondr-, salir → saldr-, decir → dir-, hacer → har-, poder → podr-, saber → sabr-, querer → querr-, venir → vendr-, valer → valdr-, caber → cabr-, haber → habr-. The conditional uses the same stems.

The future endings (-é, -ás, -á, -emos, -éis, -án) never change. The irregularity lives entirely in the stem, which contracts in three ways: a dropped vowel (podré, sabré, cabré, habré, querré), a vowel replaced by d (tendré, pondré, saldré, vendré, valdré), or a shortened form (diré, haré).

The conditional uses exactly the same stems with -ía endings: tendría, diría, haría. Learn one list, get two tenses.

Derived verbs inherit the stem: mantener → mantendré, suponer → supondría, deshacer → desharé. Exception: bendecir and predecir keep regular futures (bendeciré, predeciré).

## Examples
- Tendré más tiempo la próxima semana. — I'll have more time next week.
- ¿Qué harás mañana? — What will you do tomorrow?
- Dijo que vendría a las ocho. — He said he would come at eight. *(Same stem in the conditional.)*
