By TutorLily Editorial Team · Last updated

Ser in the Spanish future (futuro simple) is: yo seré, tú serás, él/ella/usted será, nosotros/as seremos, vosotros/as seréis, ellos/ellas/ustedes serán. The future of ser describes what someone or something will be at a later moment. Unlike many irregular verbs, ser uses a regular future stem (ser- + future endings).

Tip

Working with the future

The simple future ("haré", "tendré") competes with the more conversational "voy a + infinitive" construction in everyday Spanish — the going-to form is more common for near-term plans. The simple future shines in two cases: formal or more distant predictions, and conjecture about the present ("¿qué hora será?" = "what time could it be?"). About 12 high-frequency verbs use contracted future stems (har-, dir-, tendr-, pondr-, vendr-, saldr-, podr-, querr-, sabr-, habr-, valdr-, cabr-); the rest just append future endings to the full infinitive.

Questions

Frequently asked questions

How do you conjugate ser in the future tense?
The future of ser is regular: yo seré, tú serás, él/ella/usted será, nosotros/as seremos, vosotros/as seréis, ellos/ellas/ustedes serán. Unlike many irregular verbs (tener → tendré, hacer → haré), ser keeps the full infinitive 'ser-' as the future stem.
When should I use the future of ser instead of 'ir a ser'?
Both are correct. The simple future (seré médico) tends to feel more formal or distant, while 'voy a ser médico' feels more immediate and conversational. The future tense is also used for conjecture about the present: '¿Quién será?' = 'Who could it be?'
Why does the future of ser have accents on most forms?
Spanish future endings (-é, -ás, -á, -emos, -éis, -án) carry an accent mark to preserve their original stressed pronunciation. This pattern is identical for every verb in the future tense, regular or irregular.
