'Iba' is first or third person singular, it does not agree with 'nosotros'.
'Ibas' is second person singular, it does not agree with 'nosotros'.

'Trabajaban' is third person plural, it does not agree with the implicit 'tú' in the question.
'Trabajabais' is second person plural, it does not agree with the implicit subject 'tú' in the question.
4.
'Eras' is second person singular, it does not agree with 'ellos'.
'Éramos' is first person plural, it does not agree with the subject 'ellos'.

Introduction to the Imperfect Tense for Irregular Verbs in Spanish

This lesson focuses on the pretérito imperfecto (imperfect tense) of three important irregular verbs in Spanish: ser (to be), ir (to go), and ver (to see). These verbs have unique conjugation patterns that differ from regular verbs in the imperfect tense.

What You Will Learn

  • The conjugation of ser, ir, and ver in the imperfect tense for all grammatical persons.
  • How to recognize and use these irregular forms within everyday sentences related to volunteering and emergency services contexts.
  • Examples that illustrate the use of these verbs in natural situations to help reinforce your understanding.

Conjugation Highlights

Here are the key forms you need to remember:

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

Examples of Usage

Notice how these forms are used in sentences that describe habitual actions or situations in the past:

  • Yo era voluntario en la Cruz Roja.
  • ibas al hospital cada semana.
  • Ella veía ambulancias pasar por su calle.

Differences Between English and Spanish Imperfect Tense

Unlike English, which often uses auxiliary verbs and continuous forms (e.g., "was going", "used to see") to describe ongoing or habitual past actions, Spanish uses the pretérito imperfecto directly with these irregular forms. Understanding these subtle differences is crucial for expressing past habits or states accurately.

Useful Phrases and Their Translations

  • Yo era voluntario — I was a volunteer
  • Nosotros íbamos al hospital — We used to go to the hospital
  • Ellos veían los casos — They were seeing the cases / They used to see the cases
