The Imperfect Past Tense with Irregular Verbs in Spanish

This lesson covers the use of the pretérito imperfecto (imperfect past tense) for three essential irregular verbs: ser (to be), ir (to go), and ver (to see). The imperfect tense in Spanish is used to describe ongoing or habitual past actions, and this lesson focuses specifically on how these three verbs change from the regular conjugation patterns.

What You Will Learn

  • Irregular conjugations of ser, ir, and ver in the imperfect past tense.
  • Personal pronouns and their corresponding irregular verb forms (yo, tú, él/ella, nosotros/nosotras, vosotros/vosotras, ellos/ellas).
  • Examples that place these verbs in practical, everyday situations related to emergency services contexts.

Key Irregular Forms

Here are the most important verb forms for each personal pronoun:

  • Ser: era, eras, era, éramos, erais, eran
  • Ir: iba, ibas, iba, íbamos, ibais, iban
  • Ver: veía, veías, veía, veíamos, veíais, veían

Usage in Context

These verbs appear frequently when describing past habitual actions or ongoing states. For example:

  • "Yo era voluntario en la Cruz Roja." (I was a volunteer at the Red Cross.)
  • "Tú ibas al centro médico en bici." (You used to go to the medical center by bike.)
  • "Ella veía pacientes graves a diario." (She used to see seriously ill patients daily.)

Differences Between English and Spanish Usage

In English, the past continuous or simple past might correspond to several Spanish past tenses. Spanish uses the pretérito imperfecto to describe repeated or habitual past actions or background information, which isn't always explicitly marked in English.

Unlike English, Spanish verbs change form significantly depending on person and number, especially in the imperfect tense with irregular verbs like ser, ir, and ver.

Useful Expressions

  • Era voluntario: I was a volunteer
  • Ibamos al hospital: We used to go to the hospital
  • Veías las instrucciones: You used to see the instructions

Remember these expressions focus on past habitual or ongoing states rather than completed actions.
