To change regular verbs into the simple past tense in Spanish, you can follow some simple rules.

These rules depend on the ending of the verb.

Let’s look at three groups: -AR, -ER, and -IR verbs.

Regular -AR Verbs (like "hablar" which means "to talk")

1. yo: change the ending to -é (hablé - I talked)
2. tú: change the ending to -aste (hablaste - you talked)
3. él/ella/usted: change the ending to -ó (habló - he/she/you talked)
4. nosotros/nosotras: change the ending to -amos (hablamos - we talked)
5. vosotros/vosotras: change the ending to -asteis (hablasteis - you all talked)
6. ellos/ellas/ustedes: change the ending to -aron (hablaron - they/you all talked)

Regular -ER Verbs (like "comer" which means "to eat")

1. yo: change the ending to -í (comí - I ate)
2. tú: change the ending to -iste (comiste - you ate)
3. él/ella/usted: change the ending to -ió (comió - he/she/you ate)
4. nosotros/nosotras: change the ending to -imos (comimos - we ate)
5. vosotros/vosotras: change the ending to -isteis (comisteis - you all ate)
6. ellos/ellas/ustedes: change the ending to -ieron (comieron - they/you all ate)

Regular -IR Verbs (like "vivir" which means "to live")

1. yo: change the ending to -í (viví - I lived)
2. tú: change the ending to -iste (viviste - you lived)
3. él/ella/usted: change the ending to -ió (vivió - he/she/you lived)
4. nosotros/nosotras: change the ending to -imos (vivimos - we lived)
5. vosotros/vosotras: change the ending to -isteis (vivisteis - you all lived)
6. ellos/ellas/ustedes: change the ending to -ieron (vivieron - they/you all lived)

Important Points

• Pay attention to the endings for each group of verbs.
• Some verbs might be a little different in the present tense but follow these regular rules in the past tense.

By learning these changes, you can easily talk about things that happened in the past!
