PRETERITE TENSE
ER & IR Preterite: Regular and Spell-changing i to y
| Question | Answer |
|---|---|
| In ER & IR verbs that have the vowel A, E or O immediately before the ending, the letter "i" always carries _____ | an accent mark |
| Yo form | -í yo comí |
| Tú form | -iste tú comiste |
| Él, Ella, Usted form | -ió él comió |
| Nosotros form | -imos nosotros comimos |
| Vosotros form | -isteis vosotros comisteis |
| Ellos, Ellas, Ustedes form | -ieron vosotros comisteis |
| Verbs that have a vowel before -ER or -IR ending | only change in the él, ella, usted and ellos, ellas, ustedes forms |
| Él, Ella, Usted form (changed) | -yó él cayó |
| Ellos, Ellas, Ustedes form (changed) | -yeron ellos cayeron |
| I fell | yo caí |
| you informal fell | tú caíste |
| he/she/you formal fell | él/ella/usted cayó |
| we fell | nosotros caímos |
| you all Spain fell | vosotros caísteis |
| They/ you all fell | ellos/ellas/ustedes cayeron |
| I read | yo leí |
| you informal read | tú leíste |
| he/she/you formal read | él/ella/usted leyó |
| we read | nosotros leímos |
| you all Spain read | vosotros leísteis |
| They/ you all read | ellos/ellas/ustedes leyeron |
| I heard | yo oí |
| you informal heard | tú oíste |
| he/she/you formal heard | él/ella/usted oyó |
| we heard | nosotros oímos |
| you all Spain heard | vosotros oísteis |
| They/ you all heard | ellos/ellas/ustedes oyeron |
| only when the vowel immediately before -ER or -IR ending is A E O | add accent mark on the "í" of every form in the Preterite conjugation, examples: caer, leer, oír |
| yo distribuir | distribuí |
| tú distribuir | distribuiste |
| él/ella/usted distribuir | distribuyó |
| nosotros distribuir | distribuimos |
| vosotros distribuir | distribuisteis |
| ellos/ellas/ustedes distribuir | distribuyeron |
| distribuir does not have an accent mark on every form of the preterite | because the vowel immediately before the ending is U (not A E O) |
| él/ella/usted: drop i of ió and replace it with y | yó |
| Ellos/ellas/ustedes: drop I of ieron and replace with y | yeron |
| ER & IR Regular Endings | -í -iste -ió -imos -isteis-ieron |
| ER & IR endings for verbs with the vowel U before the ending | -í -iste -yó -imos -isteis-yeron |
| ER & IR endings for verbs with the vowels A E or O before the ending | -í -íste -yó -ímos -ísteis-yeron |
| strong vowels | A E O |
| weak vowels | I U |
