Poder Preterite Tense Conjugation in Spanish

The preterite of poder — to can — is the form you need for finished actions in the past. Poder means can and to be able to: ability, permission and possibility. It follows the o → ue stem change in the present (puedo, puedes, puede) and takes the irregular preterite pude and the future stem podr-. It usually comes before another infinitive: puedo hablar, no puedo salir. This page gives you the complete preterite table for poder, how it is formed, when to use it, the mistakes learners make with it, and a quiz to check yourself. The first example shows it in action: “Ayer yo pude terminar el trabajo.” — “Yesterday I managed to finish the work”.

Preterite conjugation of poder

Every form in the table below comes from VerbFlow’s verified conjugation tables for poder. Poder is an o → ue stem-changing irregular -er verb (irregular in present, preterite, future, conditional, present-subjunctive, imperfect-subjunctive, imperative-affirmative, imperative-negative), so watch out for the forms that break the pattern — they are the ones learners need to memorise.

Preterite indicative — poder

Person Form
yo pude
tú pudiste
él/ella/Ud. pudo
nosotros/as pudimos
vosotros/as pudisteis
ellos/ellas/Uds. pudieron

The gerund of poder is podiendo and the past participle is podido. The participle matters here because the preterite is often confused with the perfect tenses — keep them apart.

How the preterite of poder is formed

The preterite of poder does not follow the regular pattern. If poder were regular, the preterite forms would be yo → podí, tú → podiste, él/ella/Ud. → podió, nosotros/as → podimos, vosotros/as → podisteis, ellos/ellas/Uds. → podieron — but poder breaks the pattern in this tense: the forms are pude, pudiste, pudo, pudimos, pudisteis and pudieron.

The preterite stem here is pud-, which you cannot get from the infinitive by rule — it has to be learnt as part of the verb. The endings then attach to that stem: pude, pudiste, pudo, pudimos, pudisteis and pudieron. This is the same pattern the verb follows in the imperfect subjunctive, which is built on the preterite third-person plural, so learning the preterite pays twice.

A note on spelling: none of the preterite forms of poder carries a written accent, which is one less thing to memorise — but do not add one by habit. Copy the forms from the table above exactly as written.

When to use the preterite of poder

1. Completed actions at a specific time

Use the preterite for an action that started and finished in the past. For example, with poder: “Ayer yo pude terminar el trabajo.” — “Yesterday I managed to finish the work”. Notice how the time expression and the context, not just the verb form, tell you which rule applies.

2. A sequence of actions

Use the preterite to list one finished action after another. For example, with poder: “Ella pudo resolver el problema sola.” — “She managed to solve the problem alone”. Notice how the time expression and the context, not just the verb form, tell you which rule applies.

3. Actions that interrupt an ongoing situation

Use the preterite for the action that breaks into a longer background scene. For example, with poder: “Nosotros pudimos comprar las entradas.” — “We managed to buy the tickets”. Notice how the time expression and the context, not just the verb form, tell you which rule applies.

4. Sudden changes and achievements

Use the preterite for a change of state or something achieved at one moment. For example, with poder: “Ellos no pudieron venir a tiempo.” — “They could not come on time”. Notice how the time expression and the context, not just the verb form, tell you which rule applies.

Preterite vs imperfect: poder finished, poder in progress

The preterite and the imperfect are the two past tenses, and choosing between them is the hardest decision in Spanish past-tense grammar. The preterite is for what happened and finished; the imperfect is for what was happening, what used to happen, and the background. Compare the pairs below — the preterite form comes from this page, the imperfect form from the full conjugation table.

  • Preterite tense: “Ayer yo pude hablar español.” — “Yesterday I could speak Spanish.”

  • Imperfect: “De niño, yo podía hablar español.” — “As a child, I used to can speak Spanish.”

Common mistakes with poder in the preterite

Mistake 1

Wrong: Yo podo hablar español.

Right: Yo pude hablar español.

Poder changes o to ue in the present: puedo, not podo.

Mistake 2

Wrong: Ayer yo podí terminar.

Right: Ayer yo pude terminar.

The preterite is pude, with the irregular pud- stem — never podí.

Mistake 3

The o → ue stem change applies to the stressed forms of poder — the yo form is pude, not the plain stem.

Frequently asked questions

Is poder regular in the preterite?

No. poder is irregular in the preterite: the forms are pude, pudiste, pudo, pudimos, pudisteis and pudieron. There is no rule that produces them from the infinitive, so they have to be learnt as a set — the quiz above is a good place to start.

What is the yo form of poder in the preterite?

It is pude. The yo form is the one learners use most and the one that most often breaks the pattern — for poder it is the form to learn first, before the rest of the table.

When do I use the preterite of poder instead of the present?

Use the preterite when the action is finished and tied to a specific moment — yesterday, last week, at eight o’clock. If the action was ongoing, habitual, or just background to another event, the imperfect is the right choice, not the preterite.
