Exercise 2: Multiple Choice

Instruction: Select the correct sentence in the simple past tense (pretérito indefinido) of regular or irregular verbs for each situation. Pay attention to endings and accents, and avoid common errors in the conjugation of the simple past tense.

1.
Error: The form 'vié' does not exist; 'ver' is conjugated as 'vi' in the first person singular of the past tense.
Error: The verb 'ver' in the simple past tense does not carry an accent in first person singular. 'Ví' is incorrect.
2.
Error: The form 'preguntamosé' does not exist; the correct form for 'nosotros' in the past tense is 'preguntamos'.
Error: Although the form 'preguntamos' is the same in present and past, the context here is appropriate; this option remains correct.
3.
Error: Missing accent in 'explicó', which is necessary to distinguish the past from the present.
Error: 'Explició' is not a correct form; the correct ending for third person singular is '-ó' with an accent.
4.
Error: 'Vivieronon' does not exist; the correct ending is '-ieron' without added letters.
Error: 'Vivió' is third person singular, not plural. The correct form for 'ellos' is 'vivieron'.

Understanding the Spanish Preterite Indefinite: Irregular Verbs

This lesson focuses on the pretérito indefinido tense in Spanish, especially on irregular verbs. The pretérito indefinido is used to describe actions completed in the past, and many common verbs change their roots or conjugation patterns in this tense.

Key Irregular Verbs and Their Roots

Some of the most frequently used irregular verbs include hacer (hic- / hiz-), poder (pud-), poner (pus-), querer (quis-), saber (sup-), estar (estuv-), tener (tuv-), dar, ser, and ir. Each of these verbs has distinctive root changes and conjugation endings.

Conjugation Endings for Irregular Verbs

Irregular verbs in the preterite have specific endings that differ from regular verbs: -e, -iste, -o, -imos, -isteis, -ieron. Notice that ser and ir share identical conjugations: fui, fuiste, fue, fuimos, fuisteis, fueron. Importantly, these irregular preterite forms do not carry accent marks.

Additional Irregularities

  • Some verbs are mainly regular but change vowels in the third person singular and plural, e.g., dormir -> durmió, pedir -> pidió.
  • Other verbs change consonants in these persons, such as leer -> leyó.
  • Verbs ending in -zar, -gar, -car have spelling changes in the first person singular to preserve pronunciation: pagar -> pagué.

Example Sentences

  • Hice un reportaje sobre las noticias actuales.
  • No pude volver a ver el programa.
  • El presentador nos dio una buena noticia.
  • Tú fuiste un presentador.

Note on Differences Between English and Spanish

Unlike English, Spanish uses a specific past tense for completed actions called the pretérito indefinido, which often involves irregular stem changes and special endings. English past verbs usually take a single regular form (like "walked") or unique irregular past forms (like "went").

Some useful Spanish phrases showing preterite use are:

  • Hice (I did/made) – contrasting with English "I did"
  • Tuve (I had) – differs from the simple past "had" but corresponds in meaning
  • Fui (I was/went) – one form for both verbs "ser" and "ir"

Understanding these differences helps learners use past actions accurately in Spanish.
