What Is an Irregular Verb?

In Spanish, there are three regular conjugations for verbs that end in -ar, for verbs that end in -er, and for verbs that end in -ir. Irregular verbs don’t follow the regular conjugation rules.

Only 5% of -ar verbs are irregular. Among -er verbs, you’ll find 33% that are irregular. The most difficult ones are the -ir verbs—72% of them are irregular.

Irregular verbs aren’t necessarily irregular in all the tenses. Some verbs don’t follow the rules just in the present tense, others in the present tense and the preterite tense, and others are irregular in three or more tenses.

Irregular Preterite Spanish Verb Categories

We can divide the irregular preterite Spanish verbs into three groups:

1. Verbs with Regular Preterite Endings and Minor Stem Changes

These are the regular endings for each conjugation:

Preterite Endings: Regular -ar Verbs

Yo – é

Tú -aste

Él, ella, Ud. – ó

Nosotros -amos

Ustedes -aron

Ellos, ellas -aron

For example: hablar (to talk) – hablé, hablaste, habló, hablamos, hablaron, hablaron.

Preterite Endings: Regular -er and -ir Verbs

Yo -í

Tú -iste

Él, ella, Ud. -ió

Nosotros -imos

Ustedes -ieron

Ellos, ellas -ieron

For example:

• correr (to run): corrí, corriste, corrió, corrimos, corrieron
• abrir (to open): abrí, abriste, abrió, abrimos, abrieron

The following irregular preterite verbs keep the regular endings but suffer some other changes inside the stem.

Just a quick reminder; a stem is what you get when you cut off the infinitive ending (–ar, -er, -ir) from the verb. For example, for the verb comer (to eat), the stem is com-.

-ir Verbs with Small Stem Changes

The –ir irregular preterite verbs that keep the regular –ir endings involve three types of changes:

• e to i
• o to u
• accent changes

These changes occur ONLY in the third-person singular and the second- and third-person plural.

On this list of 50 irregular Spanish verbs, there are five verbs with the e to i change, two verbs with the o to u change, and two verbs with accent changes.

Preterite Conjugation for e to i Stem Changes: sentir (to feel)

¿Cómo se sintió el temblor?
How did the earthquake feel?

Other verbs on the list that conjugate like this are pedir (to ask for), conseguir (to get, achieve), repetir (to repeat), and vestirse (to dress).

Preterite Conjugation for o to u Stem Changes: dormir (to sleep)

Juan se durmió tarde y no se levantó a tiempo.
Juan slept late and did not wake up on time.

The verbs that undergo accent changes are reír and sonreír. They both lose the accent mark over the i in the third-person singular and in the second- and third-person plural, but reír also loses the accent mark in the third person ending, whereas sonreír doesn’t.

Preterite Conjugation with Accent Changes: reír (to laugh)

Se rio a carcajadas de su chiste.
He laughed out loud at her joke.

Preterite Conjugation with Accent Changes: sonreír (to smile)

¡No me sonrieron cuando me vieron!
They didn’t smile when they saw me!

Preterite Verbs That Change in the Yo Form

Three types of verbs have an irregular stem in the first person but they keep the regular preterite endings:

• verbs that end in -car
• verbs that end in -gar
• verbs that end in -zar

Preterite Conjugation for Verbs Ending in -car: tocar (to touch)

The letter c changes to qu for pronunciation reasons, if it didn’t you would pronounce the word *tocé as /to’se/ instead of /to‘ke/.

¡El año pasado toqué un delfín!
Last year, I touched a dolphin!

Preterite Conjugation for Verbs Ending in -gar: pagar (to pay)

You have to add the letter u after the letter g to keep the original pronunciation.

Pagué en efectivo.
I paid in cash.

Preterite Conjugation for Verbs Ending in -zar: organizar (to organize)

The letter z changes to c for the same reasons as for the verbs above.

Para mi cumpleaños, organicé la fiesta del año.
For my birthday, I organized the party of the year.

Preterite Verbs with Additional y

Some -er and -ir verbs change the letter i in the third-person singular, and the second- and third-person plural:

• verbs ending in -eer, -caer, -oír, and –oer
• verbs ending in -uir

Both groups gain the letter y in the grammatical subjects I mentioned, but the first group also has an accent over the letter i in all the other grammatical subjects.The verbs that end in –uir never have an accent mark over the letter i in the preterite ending.

Preterite Conjugation for –eer Verbs: creer (to believe)

No me creyó y yo sí le creí.
He didn’t believe me and I believed him.

Preterite Conjugation for –caer Verbs: caer (to fall)

¡Jaja! !Caíste! Y todo esto fue una broma.
Haha! You fell for it! And this was all a joke.

Preterite Conjugation for –oír Verbs: oír (to hear)

Se oyó un trueno.
A clap of thunder was heard.

Preterite Conjugation for –oer Verbs: corroer (to corrode)

Fueron dos chicos nada más y corroyeron todo el grupo.
These were only two boys and they corroded the whole group.

Here is a -uir verb with no accent over the i:

Preterite Conjugation for –uir Verbs: huir (to run away, to flee)

Hui del país pero él huyó de su pasado.
I fled the country but he fled his past.

Irregular preterite endings:

UV-stem verbs

The verbs in this group gain the uv in their preterite stem plus the irregular preterite endings: tener (to have), andar (to walk), estar (to be), detener (to stop), retener (to retain, to keep), and contener (to contain, to hold).

Preterite Conjugation for UV-stem Verbs: tener (to have)

U-stem Verbs

The verbs in this group gain the U in their preterite stem. The consonant in the stem will also change in some cases (n to s, b to p).

These are the verbs in this group: poner (to put), poder (can), saber (to know), caber (to keep), componer (to compose), descomponer (to decompose), and proponer (to propose).

Can you try conjugating saber? Remember to put the letter u in the stem, and change b to p.

The verbs that belong to this group include: venir (to come), convenir (to agree), prevenir (to prevent), hacer (to do), querer (to want), deshacer (to undo), and rehacer (to redo).

Venir and other verbs that end like it just swap the vowel in their stem.

Preterite Conjugation for I-stem Verbs: venir (to come)

Su reconocimiento vino tarde.

Hacer, querer, and other verbs that derive from them have some more changes. Hacer in the third-person singular changes the c to z, and the verb querer swaps the consonant r for s in all grammatical subjects.

J-stem Verbs

Most of the verbs that end in -ducir, -decir, and -traer have a letter j in their preterite stem. Apart from that, they lose the letter i in the second and third-person plural ending.

The verbs with j in the stem are: decir (to say), traer (to bring), conducir (to drive), producir (to produce), traducir (to translate), predecir (to predict), and contradecir (to contradict).

Preterite Conjugation for J-stem Verbs: traer (to bring)

The verb decir and those that derive from it also change the e in the stem for i.
