Most Spanish verbs have regular forms in the past tense, known as the pretérito in Spanish. You can review them here. But many common verbs are irregular in the pretérito. We’ll take a closer look at irregular pretérito verbs in this post.
Irregular Pretérito Endings and Stems
There are two ways that these verbs are irregular. First, the endings are slightly different than the regular pretérito endings. Remember that the regular pretérito has one set of endings for –ar verbs and another for -er/-ir verbs. Irregular pretérito verbs all use the same set of endings:
| yo | -e | nosotros/as | -imos |
| tú | -iste | vosotros/as | -isteis |
| usted/él/ella | -o | ustedes/ellos/ellas | -ieron |
Second, they use a different stem than in the present. For example, tener (to have) uses the regular stem ten– (tener minus the –er ending) in the present. It’s not totally regular of course, since it adds –g– in the yo form and has a stem vowel change e > ie: tengo (I have), tienes (you have), tiene (he/she has), tenemos (we have), tenéis (all of you have), tienen (they have).
But in the pretérito, tener uses the stem tuv– plus the endings above: tuve (I had), tuviste (you had), tuvo (he/she had), tuvimos (we had), tuvisteis (all of you had), tuvieron (they had).
We’ll group irregular pretérito verbs by stem type so that they’re easier to remember.
Verbs with -i- stems
The verbs hacer (to do/make), venir (to come) and querer (to want) have stems with i: hic-, vin-, and quis-. Note that hacer uses hiz– in the usted/él/ella form to keep the /s/ sound, which don’t forget is /th/ in Spain. To conjugate these verbs in the pretérito, just add the irregular pretérito endings.
hacer: hice, hiciste, hizo, hicimos, hicisteis, hicieron
venir: vine, viniste, vino, vinimos, vinisteis, vinieron
querer: quise, quisiste, quiso, quisimos, quisisteis, quisieron
- Quise hacer una pregunta.
I wanted to ask a question. - Quiso entender la razón.
He/She wanted to understand the reason. - Vinieron hace dos años.
They came two years ago. - Hice mi tarea anoche.
I did my homework last night. - Marta hizo una pregunta.
Marta asked a question.
Verbs with -uv- stems
Tener (to have), estar (to be) and andar (to walk) all have irregular pretérito stems with uv.
estar: estuve, estuviste, estuvo, estuvimos, estuvisteis, estuvieron
tener: tuve, tuviste, tuvo, tuvimos, tuvisteis, tuvieron
andar: anduve, anduviste, anduvo, anduvimos, anduvisteis, anduvieron
- ¿Dónde estuvieron ayer?
Where were they yesterday? - Estuve en casa.
I was home. - Nunca tuviste los síntomas.
You never had the symptoms. - Esta mañana tuvo una reunión muy larga.
He/She had a very long meeting this morning. - Anduve cinco kilómetros y llegué al parque.
I walked five kilometers and arrived at the park.
Verbs with -u- stems
The verbs poder (can, to be able), poner (to put), saber (to know), caber (to fit) and haber (to have, auxiliary verb) all have stems with u in the pretérito.
poder: pude, pudiste, pudo, pudimos, pudisteis, pudieron
poner: puse, pusiste, puso, pusimos, pusisteis, pusieron
saber: supe, supiste, supo, supimos, supisteis, supieron
caber: cupe, cupiste, cupo, cupimos, cupisteis, cupieron
haber: hube, hubiste, hubo, hubimos, hubisteis, hubieron
Saber in the pretérito can have the sense of found out or knew how, and poder in the pretérito has the sense of managed to.
- Supe la verdad.
I found out the truth. - Supieron contestar correctamente.
They knew how to answer correctly. - ¿No pudiste ayudarlo?
You weren’t able/didn’t manage to help him? - Finalmente pude hacerlo.
Finally I managed to/was able to do it. - Me puse una camisa nueva.
I put on a new shirt. - No cupo en la maleta.

Haber is used to mean there is/there are, with the form hay in the present. In the past, it’s hubo.
- Hubo una tormenta.
There was a storm. - Hubo muchas personas.
There were a lot of people.
Verbs with stems that end in vowels
A couple of common verbs that have stems ending in vowels followed a different pattern. These are leer (to read), caer (to fall), oír (to hear) and concluir (to conclude). They take endings similar to the regular -er/-ir pretérito endings [link], there’s an accented vowel in all of the endings but ellos/ellas, and they use –y– in the él/ella and ellos/ellas forms. Also notice that the ellos/ellas ending in –eron and not –ieron after y. (You may have noticed that i becomes y elsewhere in Spanish, for example: caer > cayendo, leer > leyendo, oír > oyendo.)
leer: leí, leíste, leyó, leímos, leísteis, leyeron
caer: caí, caíste, cayó, caímos, caísteis, cayeron
oír: oí, oíste, oyó, oímos, oísteis, oyeron
concluir: concluí, concluiste, concluyó, concluimos, concluisteis, concluyeron
- ¿Cuándo leíste ese libro?
When did you read that book? - Leí un artículo interesante esta mañana.
I read an interesting article this morning. - Un coco cayó de la palmera.
A coconut fell from the palm tree. - Oyó un ruido fuerte.
She heard a loud noise. - Los tribunales concluyeron que no hubo discriminación.
The courts concluded that there was no discrimination.
Verbs with stems ending in j
The verbs decir (to say), traer (to bring), conducir (to drive, to conduct), producir (to produce) and traducir (to translate) all have past stems ending in j. Notice also the decir has an i in the past stem. The endings are all the irregular pretérito endings, but the ellos/ellas form uses –eron instead of –ieron after j.
decir: dije, dijiste, dijo, dijimos, dijisteis, dijeron
traer: traje, trajiste, trajo, trajimos, trajisteis, trajeron
conducir: conduje, condujiste, condujo, condujimos, condujisteis, condujeron
producir: produje, produjiste, produjo, produjimos, produjisteis, produjeron
traducir: traduje, tradujiste, tradujo, tradujimos, tradujisteis, tradujeron
- ¿Qué dijiste?
What did you say? - Me dijeron que no valía la pena.

-ir verbs with stem vowel changes
Several –ir verbs have stem vowel changes in the pretérito: sentir (to feel), pedir (to ask for), dormir (to sleep), consequir (to get/obtain), vestirse (to get dressed), repetir (to repeat), morir (to die), servir (to serve), divertirse (to have fun), sugerir (to suggest). The stem vowel changes happen in the él/ella and ellos/ellas forms, and the endings are the regular pretérito endings for -er/-ir verbs. [LINK]
sentir: sentí, sentiste, sintió, sentimos, sentisteis, sintieron
pedir: pedí, pediste, pidió, pedimos, pedisteis, pidieron
dormir: dormí, dormiste, durmió, dormimos, dormisteis, durmieron

ser/ir: fui, fuiste, fue, fuimos, fuisteis, fueron
dar: di, diste, dio, dimos, disteis, dieron
ver: vi, viste, vio, vimos, visteis, vieron
