The Past Simple of ‘be’ (was/were) helps us talk about how things were, where people were, or what someone was like in the past. It’s one of the most important verbs in English for A1 learners. We use was for singular subjects like I, he, she, it, and singular nouns (e.g., the dog). We use were for plural subjects like you, we, they, and plural nouns (e.g., the students). This verb is special because it doesn’t need did to form questions or negatives; it changes its own form. For example, I was happy yesterday, They were at home, She wasn’t sad, Were you busy?.

What is the Past Simple of ‘Be’?

The verb be is very common in English. In the present, it has three forms: am, is, are. In the past, it only has two forms:

  • was
  • were

We use these forms to talk about things that happened or were true at a specific time in the past.

Errores habituales de los hispanohablantes

Spanish speakers sometimes make mistakes with the Past Simple of ‘be’ because of differences between English and Spanish.

  • Using ‘did’ with ‘be’: In Spanish, you might use an auxiliary verb. But in English, ‘be’ is special. Do NOT use did with was o were.
    Incorrecto: I didn’t was happy.
    Correcto: I wasn’t happy.
    Incorrecto: Did you were tired?
    Correcto: Were you tired?
  • Confusing ‘ser’ and ‘estar’: In Spanish, you have two verbs for ‘be’ (ser y estar). In English, be covers both. Don’t try to translate them separately.
    Ejemplo: He was a doctor. (Era un médico – ser)
    Ejemplo: He was in the hospital. (Estaba en el hospital – estar)
