The Spanish future and conditional: one stem, two sets of endings

The future says what will happen; the conditional says what would happen. Both add endings to the whole infinitive, and both share the same twelve irregular stems. Learn one, and you have both.

hablar- hablaré · I will speak hablaría · I would speak IRREGULAR STEMS, SAME ENDINGS tener → tendré, tendría hacer → haré, haría decir → diré, diría The conditional endings -ía, -ías, -ía are the same as the -er imperfect (comía). The stem decides which tense you hear.

Ir a + infinitive: the everyday future

In conversation, plans are usually expressed with ir a + infinitive, like English “going to”. The simple future sounds more formal, more certain, or more distant.

The endings, for every verb

Unlike other tenses, the future and conditional are built on the whole infinitive (the dictionary form, ending in -ar, -er or -ir). Add the endings straight on: one set for all three verb groups. The irregular verbs only change the stem; the endings stay the same.

REGULAR vivir + é →viviré · viviríanothing removed: the whole infinitive stays IRREGULAR tener → tendr- →tendré · tendríae drops out, d is added Other patterns: poder → podr- (vowel drops) · hacer → har-, decir → dir- (shortened)
The future and conditional always share a stem: if you know tendré, you know tendría.

The twelve irregular stems

Beyond time: probability and politeness

Guessing nowThe future expresses a guess about the present: “must be”, “I wonder”.
¿Dóndewhereestará(he) will-beJuan?JuanEstará(he) will-beenatcasa.home
DON-deh es-tah-RAH HWAN? es-tah-RAH en KAH-sah“Where can Juan be? He’s probably at home.”
Guessing the pastThe conditional guesses about the past. The time is plural (las diez), so serían.
Serían(they) would-belasthedieztencuandowhenllegó.(he) arrived
seh-REE-an lahs DYETH KWAN-doh yeh-GOH“It must have been about ten when he arrived.”
Polite requestsThe conditional softens a request: podría is gentler than puede.
¿Podría(you) couldayudarme?help-me
poh-DREE-ah ah-yoo-DAR-meh“Could you help me?”
WishesGustaría is the polite way to say what you want, instead of quiero.
Meto-megustaríawould-pleaseviajar.to-travel
meh goos-tah-REE-ah bee-ah-HAR“I’d like to travel.”
AdviceDeberías, “you should”, gives advice without sounding like an order.
Deberías(you) shoulddescansar.to-rest
deh-beh-REE-ahs des-kan-SAR“You should rest.”

Si clauses: real and imagined

After si (if), Spanish never uses the future or conditional. For an imagined condition it uses the imperfect subjunctive.

After cuando: subjunctive, not future

Cuando llegues, llámame

A trap: after cuando (when), en cuanto (as soon as) and hasta que (until) about the future, Spanish uses the present subjunctive (a verb form for things not yet real), never the future. The main clause takes the future or a command.

Cuandowhenllegues,you-arrivellámame.call-me
KWAN-doh YEH-ges, YAH-mah-meh · “When you arrive, call me.”
En cuantoas-soon-aspueda,I-cante escribiré.to-you I-will-write

EsperaréI-will-waithasta queuntilvuelvas.you-return
es-peh-rah-REH AS-tah keh BWEL-bahs · “I’ll wait until you come back.”
Perfect future and conditional

Habría ido, habrá terminado

Habrá + participle looks back from a future moment; habría + participle is what would have happened. Both also guess about the past: Habrá salido, “he must have gone out”.

  1. Future perfect
    A las ochoat eighthabré terminado.I-will-have finished
    ah lahs OH-choh ah-BREH tehr-mee-NAH-doh · “I’ll have finished by eight.”
  2. Guess about the past
