Why so many irregulars?
Unfortunately, many of the most frequently used Spanish verbs have irregular preterite forms. The good news is that several share the same set of endings, so once you learn the pattern, you can apply it to multiple verbs at once.
Ir (to go) and Ser (to be)
These two verbs have identical preterite forms. Context makes the meaning clear:
| Person | Form | Ir meaning | Ser meaning |
|---|---|---|---|
| yo | fui | I went | I was |
| tu | fuiste | you went | you were |
| el/ella/usted | fue | he/she went | he/she was |
| nosotros | fuimos | we went | we were |
| vosotros | fuisteis | you all went | you all were |
| ellos/ustedes | fueron | they went | they were |
- Fui al cine ayer. - I went to the cinema yesterday. (ir)
- Fue un dia increible. - It was an incredible day. (ser)
- Fuimos a la playa. - We went to the beach. (ir)
- Fueron muy amables. - They were very kind. (ser)
The "pretzel" group - irregular stems with shared endings
These verbs share a special set of endings: -e, -iste, -o, -imos, -isteis, -ieron. Notice there are no accent marks on these endings - unlike regular preterites.
| Verb | Irregular stem | Yo | El/Ella | Ellos |
|---|---|---|---|---|
| tener (to have) | tuv- | tuve | tuvo | tuvieron |
| estar (to be) | estuv- | estuve | estuvo | estuvieron |
| poder (to be able) | pud- | pude | pudo | pudieron |
| poner (to put) | pus- | puse | puso | pusieron |
| saber (to know) | sup- | supe | supo | supieron |
| hacer (to do/make) | hic- | hice | hizo | hicieron |
| querer (to want) | quis- | quise | quiso | quisieron |
| venir (to come) | vin- | vine | vino | vinieron |
| decir (to say) | dij- | dije | dijo | dijeron |
| traer (to bring) | traj- | traje | trajo | trajeron |
Note: Hacer changes c → z in the el/ella form: hizo (not hico). Verbs with stems ending in -j (decir, traer) use -eron instead of -ieron in the ellos form.
Full conjugation example: tener
| Person | Conjugation | Person | Conjugation |
|---|---|---|---|
| yo | tuve | nosotros | tuvimos |
| tu | tuviste | vosotros | tuvisteis |
| el/ella | tuvo | ellos | tuvieron |
Dar (to give) and Ver (to see)
These short verbs take -er/-ir endings but without accent marks:
| Person | dar | ver |
|---|---|---|
| yo | di | vi |
| tu | diste | viste |
| el/ella | dio | vio |
| nosotros | dimos | vimos |
| vosotros | disteis | visteis |
| ellos | dieron | vieron |
Hay → Hubo
The impersonal hay (there is/are) becomes hubo in the preterite (there was/were):
- Hubo un accidente en la carretera. - There was an accident on the road.
- Hubo muchos problemas. - There were many problems.

Key takeaways

- Dar and ver take -er/-ir endings with no accents.
