The Irregular Preterite Endings
Most irregular verbs add these endings to a special stem:
There are no written accents on these endings.
Example: tener uses the stem tuv-, so tuve, tuviste, tuvo, tuvimos, tuvisteis, tuvieron.
tener in the Preterite
| Subject | Preterite | Meaning |
|---|---|---|
| yo | tuve | I had |
| tú | tuviste | you had |
| él / ella / usted | tuvo | he/she/you had |
| nosotros | tuvimos | we had |
| vosotros | tuvisteis | you all had |
| ellos / ustedes | tuvieron | they / you all had |
Tuve un examen. (I had an exam.)
IR and SER: Identical Twins
Ir (to go) and ser (to be) share the same preterite. Context tells you the meaning.
| Subject | Preterite |
|---|---|
| yo | fui |
| tú | fuiste |
| él / ella / usted | fue |
| nosotros | fuimos |
| vosotros | fuisteis |
| ellos / ustedes | fueron |
Fui al cine ayer. (I went to the cinema yesterday.)

The U-Stem Group
These common verbs take a stem with u, then add the irregular endings.
| Infinitive | Stem | Example |
|---|---|---|
| tener | tuv- | tuve |
| estar | estuv- | estuve |
| poder | pud- | pude |
| poner | pus- | puse |
No accents: tuve, not tuvé; tuvo, not tuvó.
U-Stem Examples

The I-Stem Group
These verbs take a stem with i.
