explain how in spanish imperfect is used to talk about the past

In Spanish, the imperfect tense is used to talk about ongoing or repeated past actions or events. It is used to describe a situation, background information, or a habitual action in the past. It is often used to set the stage or provide context for a specific event that occurred in the past.

The imperfect tense is formed by adding specific endings to the stem of the verb. The endings for -ar verbs are -aba, -abas, -aba, -ábamos, -abais, -aban; for -er and -ir verbs, the endings are -ía, -ías, -ía, -íamos, -íais, -ían.

Here are some examples:

1. Cuando era niño, siempre jugaba en el parque. - When I was a child, I always used to play in the park.
- "Era" (imperfect of "ser") and "jugaba" (imperfect of "jugar") describe ongoing actions or states in the past.

2. Durante las vacaciones, íbamos a la playa todos los años. - During vacations, we used to go to the beach every year.
- "Íbamos" (imperfect of "ir") describes a repeated action in the past.
