Creer Conjugation: Every Tense with Examples

Creer means to believe or to think (have an opinion). Mostly regular -er. Preterite 3rd person shifts i→y (creyó, creyeron). Imperfect / past participle carry accent on í (creía, creído).

Creo que sí.

I think so.

What it is

Creer means to believe or to think (have an opinion). Mostly regular -er with two spelling quirks: 3rd-person preterite shifts i→y (creyó, creyeron), and the imperfect / past participle carry an accent on every í (creía, creído).

In Creo que sí (I think so), creo is the regular yo present. Negative no creer que triggers subjunctive: No creo que sea verdad (I don't think it's true).

How to spot it

Present is regular. Preterite 3rd person: creyó, creyeron. Imperfect and past participle: creía, creído (with accents).

  • Creo que tienes razón. — I think you're right.
  • No me lo creyó. — She didn't believe me.
  • He creído en ti. — I've believed in you.

Same i→y family as leer (leyó), caer (cayó), oír (oyó). All -eer / -aer / -oír verbs share this preterite pattern.

How to Conjugate Creer Across Tenses

Present, Regular -er

Fully regular: creo, crees, cree, creemos, creéis, creen.

Yo creo, tú crees, él cree, nosotros creemos, vosotros creéis, ellos creen.

I believe, you believe, he believes, we believe, you all believe, they believe.

No stem changes in the present, same pattern as como, leo.

Preterite, I→Y in 3rd Person

Yo / tú / nosotros / vosotros take accented í: creí, creíste, creímos, creísteis. 3rd person shifts i→y: creyó, creyeron.

Creí lo que me dijiste. Él no me creyó.

I believed what you told me. He didn't believe me.

Same i→y family as leer (leyó), caer (cayó), oír (oyó), poseer (poseyó).

Imperfect, Accent on Every Í

Imperfect carries accent on every í: creía, creías, creía, creíamos, creíais, creían.

Antes creía en Santa Claus.

I used to believe in Santa Claus.

Required because of the hiatus (e-í-a), same as leía, traía, caía.

Past Participle, Creído (With Accent)

Past participle is creído (with accent on í). Used in compound tenses: he creído, había creído, haya creído.

He creído en ti siempre.

I've always believed in you.

Same accent rule as leído, traído, caído, break the hiatus with accented í.

Common Mistakes with Creer Conjugation

Incorrect: Él me creió. — He believed me. (wrong, 3rd person preterite i→y)

Correct: Él me creyó. — He believed me.

Creer shifts i→y in 3rd-person preterite to avoid an unstressed i between vowels. Creyó / creyeron.

Incorrect: He creido en ti. — I've believed in you. (wrong, past participle needs accent)

Correct: He creído en ti. — I've believed in you.

Creído carries an accent on í because of the hiatus (e-í-o). Required in writing.

Incorrect: No creo que es verdad. — I don't think it's true. (wrong, needs subjunctive)

Correct: No creo que sea verdad. — I don't think it's true.

No creer que triggers subjunctive in the dependent clause. Use sea (subjunctive), not es (indicative).
