The rule at a glance

Endings: -ía, -ías, -ía, -íamos, -íais, -ían; Same endings for -ar, -er and -ir verbs

  • Would

    viajaría

    I would travel

    Si tuviera dinero, viajaría por el mundo.

    If I had money, I'd travel the world.

    you could

    ¿Podrías ayudarme?

    Could you help me?

  • The same 12 irregular stems as the future, e.g. tendr-, har-, dir-, podr-, sabr-, querr-, vendr-, saldr-, pondr- give tendría, haría, diría.
  • Every ending has an accent on the í: hablaría, comeríamos, vivirían.
  • In an imaginary "if" sentence, the si part takes the imperfect subjunctive and the result takes the conditional: Si tuviera dinero, viajaría (not Si tendría).

Forms

Regular verbs

The conditional (the "would" tense) is formed like the simple future: the endings go on the whole infinitive, and one set of endings works for -ar, -er and -ir verbs. The endings look like the imperfect endings of -er verbs (-ía, -ías...), and every one has an accent.

The highlighted part is the ending.

hablar (to speak)comer (to eat)vivir (to live)
yohablaría – I would speakcomería – I would eatviviría – I would live
túhablarías – you would speakcomerías – you would eatvivirías – you would live
él/​ella/​ustedhablaría – he/she would speakcomería – he/she would eatviviría – he/she would live
nosotroshablaríamos – we would speakcomeríamos – we would eatviviríamos – we would live
vosotroshablaríais – you all would speakcomeríais – you all would eatviviríais – you all would live
ellos/​ellas/​ustedeshablarían – they would speakcomerían – they would eatvivirían – they would live

Irregular stems

The conditional uses exactly the same 12 irregular stems as the future: just change the endings from -é, -ás, -á to -ía, -ías, -ía (future tendré, haré, podré; conditional tendría, haría, podría).

The highlighted part is the new stem.

Regular endings:-ía, -ías, -ía, -íamos, -íais, -ían

When to use it

1. Hypothetical situations

What would happen under a condition. In an imaginary "if" sentence the si part takes the imperfect subjunctive.

If clause: Si tuviera dinero, viajaría por el mundo – If I had money, I would travel the world

Condition: Sin trabajo, no podríamos vivir aquí – Without work, we couldn't live here

Advice: En tu lugar, yo no lo haría – In your place, I wouldn't do it

2. Polite requests and wishes

The conditional softens a request: ¿Puedes ayudarme? is direct, ¿Podrías ayudarme? is polite.

Question: ¿Podrías ayudarme? Could you help me?

Order: Me gustaría un café, por favor – I would like a coffee, please

Request: ¿Sería posible cambiar la fecha? Would it be possible to change the date?

3. Advice: should, if I were you

debería(s): Deberías descansar más – You should rest more

yo que tú: Yo que tú, estudiaría más – If I were you, I would study more

sería mejor: Sería mejor esperar – It would be better to wait

4. Probability in the past

A guess about the past, as the future makes a guess about the present.

Time: Serían las tres cuando llegó – It must have been three o'clock when he arrived

Age: Tendría unos 30 años en esa foto – He was probably about 30 in that photo

State: Estaría cansado después del viaje – He was probably tired after the trip

5. The future in the past

What someone said, knew or promised would happen.

Reported: Dijo que vendría el lunes – He said he would come on Monday

Expectation: Sabía que sería difícil – I knew it would be difficult

Promise: Prometió que llamaría – He promised he would call

Common mistakes

Don't forget the accent marks

Not this (incorrect): hablaria, comerias, viviria

But this (correct): hablaría, comerías, viviría. All conditional endings need an accent mark on the í.

Use the conditional in the result, not the si clause

Not this (incorrect): Si tendría tiempo, estudiaría más

But this (correct): Si tuviera tiempo, estudiaría más – If I had time, I would study more. The si clause takes the imperfect subjunctive; the conditional goes in the main clause.

Tener has an irregular stem

Not this (incorrect): Tenería

But this (correct): Tendría – I would have. Same stems as the future: tendr- + ía.

Hacer becomes har-

Not this (incorrect): Hacería

But this (correct): Haría – I would make. Hacer drops 'ce': har- + ía.
