Preterite: Part VI
Notes:
- The written lesson is below.
- Links to quizzes, tests, etc. are to the left.
A number of verbs that are irregular in the preterite follow a particular pattern. While their stems change, they all take the following endings:
-e
-iste
-o
-imos
-isteis
-ieron
Here are the verbs, along with their corresponding stem changes:
| Infinitive | Stem Change |
|---|---|
| andar | anduv- |
| estar | estuv- |
| tener | tuv- |
| caber | cup- |
| haber | hub- |
| poder | pud- |
| poner | pus- |
| saber | sup- |
| hacer | hic- |
| querer | quis- |
| venir | vin- |
Here are two examples of how this pattern is applied:
| estar (estuv-) | saber (sup-) |
|---|---|
| estuve | supe |
| estuviste | supiste |
| estuvo | supo |
| estuvimos | supimos |
| estuvisteis | supisteis |
| estuvieron | supieron |
Note: The one exception is the third person singular of hacer. As you learned in a previous lesson, the c changes to z to form “hizo.”
