In Spanish, the preterite tense is used to describe completed actions in the past. For verbs ending in -ar, -er, and -ir, the preterite endings are added to the verb stem (the infinitive form minus the ending). Below is a comprehensive breakdown of the preterite endings, conjugation patterns, and examples to illustrate their usage.
1. Preterite Endings for Regular Verbs
The preterite endings vary depending on the verb’s infinitive ending (-ar, -er, or -ir) and the subject pronoun. Here’s the breakdown:
| Subject Pronoun | -ar Verbs | -er Verbs | -ir Verbs |
|---|---|---|---|
| yo | -é | -í | -í |
| tú | -aste | -iste | -iste |
| él/ella/usted | -ó | -ió | -ió |
| nosotros/as | -amos | -imos | -imos |
| vosotros/as | -asteis | -isteis | -isteis |
| ellos/ellas/ustedes | -aron | -ieron | -ieron |
2. Conjugation Examples
Here’s how the preterite is conjugated for regular verbs in each group:
a) -ar Verbs: Hablar (to speak)
- Yo hablé
- Tú hablaste
- Él/Ella/Usted habló
- Nosotros/as hablamos
- Vosotros/as hablasteis
- Ellos/Ellas/Ustedes hablaron
b) -er Verbs: Comer (to eat)

3. Key Observations
- Consistency: The endings for -er and -ir verbs are identical in all forms except for the él/ella/usted form, where -er verbs use -ió and -ir verbs use -ió as well.
- Accent Marks: Note the accent marks in forms like habló, comió, and vivió. These accents are essential for correct pronunciation and spelling.
- Stem Changes: Regular verbs follow this pattern, but stem-changing verbs (e.g., dormir → dormí) may have slight variations in the preterite.
4. Practical Usage
The preterite is used to describe specific past actions with a clear beginning and end. For example:
- Hablé con mi amigo ayer. (I spoke with my friend yesterday.)
- Comimos en un restaurante nuevo. (We ate at a new restaurant.)
- Vivieron en España por dos años. (They lived in Spain for two years.)
5. Common Mistakes to Avoid
- Confusing Preterite and Imperfect: The preterite describes completed actions, while the imperfect describes ongoing or habitual actions in the past.
- Incorrect Endings: Ensure you use the correct endings for each verb type (e.g., -aron for -ar verbs, -ieron for -er and -ir verbs).
- Forgetting Accent Marks: Always include accent marks where required (e.g., habló, comió).
6. Irregular Verbs in the Preterite
While this article focuses on regular verbs, it’s important to note that many common verbs are irregular in the preterite (e.g., ser, ir, ver). These verbs have unique stems and endings. For example:
- Ser (to be): Yo fui, tú fuiste, él/ella/usted fue, etc.
- Ir (to go): Yo fui, tú fuiste, él/ella/usted fue, etc.
What is the difference between preterite and imperfect?
+The preterite describes completed past actions with a clear start and end (e.g., "I ate"). The imperfect describes ongoing, habitual, or incomplete actions in the past (e.g., "I was eating").
Do all -er and -ir verbs use the same preterite endings?
+Yes, all -er and -ir verbs share the same preterite endings, except for the él/ella/usted form, where -er verbs use -ió and -ir verbs also use -ió.
Why are accent marks important in the preterite?
+Accent marks in the preterite (e.g., habló, comió) are essential for correct pronunciation and spelling, distinguishing preterite forms from other tenses.
How do I know if a verb is irregular in the preterite?
+Irregular verbs in the preterite often have unique stems and endings (e.g., ser → fui, tener → tuve). Memorization and practice are key for mastering these verbs.
By understanding and practicing these preterite endings, you’ll be well-equipped to describe past actions accurately in Spanish. ¡Buena suerte! (Good luck!)
