Chapter 29: El Pasado Imperfecto - Parte 1 - The Imperfect Past Tense - Part 1 (Regular Verbs)

¡Hola! You've learned how to use the Preterite tense to talk about completed past actions. Now, we'll introduce another essential past tense: the Imperfect (el imperfecto). The Imperfect tense is used to describe ongoing past actions, habitual actions in the past, descriptions of people, places, and situations in the past, and to set the scene. Understanding both Preterite and Imperfect is key to mastering past narration in Spanish. Let's start with regular verbs!

Objectives

By the end of this chapter, you will be able to:

Understand the concept and main uses of the Spanish Imperfect tense.
Conjugate regular -AR verbs in the Imperfect tense.
Conjugate regular -ER and -IR verbs in the Imperfect tense.
Form simple sentences to describe past habits, ongoing actions, and situations using regular verbs in the Imperfect.

Introduction/Warm-up

Think of the Imperfect as the "background" past tense. While the Preterite tells you "what happened," the Imperfect often tells you "what was happening" or "what used to happen."

(Optional Review): How do you say "I spoke" (Preterite of hablar)? (Hablé). How do you say "I ate" (Preterite of comer)? (Comí). The Imperfect will have different endings and a different feel.

Presentation of New Material

The Imperfect Tense (El Imperfecto): An Overview

The Imperfect tense is used to talk about:

Habitual or repeated actions in the past: Things you "used to do" or "would do" regularly.
Cuando era niño, yo jugaba en el parque todos los días. (When I was a child, I used to play / would play in the park every day.)
Ongoing past actions (no specific beginning or end mentioned): Actions that were in progress in the past. Often translated as "was/were -ing".
Él leía un libro cuando sonó el teléfono. (He was reading a book when the phone rang.)
Descriptions of people, places, things, and situations in the past:
La casa era grande y tenía un jardín bonito. (The house was big and had a pretty garden.)
Age and time in the past:
Yo tenía diez años. (I was ten years old.)

Eran las tres de la tarde. (It was three in the afternoon.)

Conjugation of Regular -AR Verbs in the Imperfect

To conjugate regular -AR verbs in the Imperfect, remove the -ar ending and add the following endings. Note the accent on the "nosotros" form!

Pronoun	-AR Ending	Example: hablar (to speak)
yo	-aba	hablaba
tú	-abas	hablabas
él/ella/usted	-aba	hablaba
nosotros/as	-ábamos	hablábamos
vosotros/as	-abais	hablabais
ellos/ellas/ustedes	-aban	hablaban

Yo caminaba al colegio todos los días. (I used to walk to school every day.)

Conjugation of Regular -ER and -IR Verbs in the Imperfect

Regular -ER and -IR verbs share the same set of endings in the Imperfect. Note that all these endings begin with an accented -í-.

Pronoun	-ER/-IR Ending	Example: comer (to eat) [-ER]	Example: vivir (to live) [-IR]
yo	-ía	comía	vivía
tú	-ías	comías	vivías
él/ella/usted	-ía	comía	vivía
nosotros/as	-íamos	comíamos	vivíamos
vosotros/as	-íais	comíais	vivíais
ellos/ellas/ustedes	-ían	comían	vivían

Nosotros escribíamos cartas a nuestros abuelos. (We used to write letters to our grandparents.)

Ella bebía mucho té cuando hacía frío. (She used to drink a lot of tea when it was cold.)

Pronunciation Tips:

For -AR verbs, the stress naturally falls on the first 'a' of the ending (e.g., hablaba), except for nosotros where the accent on -ábamos guides you.
For -ER/-IR verbs, the accent mark on the 'i' (-ía, -ías, -íamos, -íais, -ían) is crucial for pronunciation and meaning. Ensure you stress this 'i'.

Practice Activities

Recognition Practice:

Cultural Insight

The Imperfect tense is essential for storytelling and reminiscing, which are important social activities in all cultures. When sharing childhood memories or talking about how things "used to be," Spanish speakers rely heavily on the Imperfect.

It's also key for setting the scene in narratives – describing the weather, the time, what people were doing, or how things looked, before recounting specific events (which often use the Preterite).

Language Nuances: Imperfect Tense Usage

1. Ongoing vs. Completed Past Actions

This is the core difference between Imperfect and Preterite (which we've started learning).

Imperfect: Describes actions that were ongoing, habitual, or set the scene in the past, without a specific focus on their completion. Think "was/were -ing" or "used to do."
Example: Yo leía un libro. (I was reading a book. / I used to read a book.) - The focus is on the process or habit.
Preterite: Describes actions that were completed at a specific point or viewed as a single, finished event.
Example: Yo leí el libro ayer. (I read the book yesterday.) - The action of reading that specific book is completed.

We will explore this contrast in more detail after learning the irregular Imperfect verbs.

2. "Yo" and "Él/Ella/Usted" Forms are Identical

For both -AR verbs (ending in -aba) and -ER/-IR verbs (ending in -ía) in the Imperfect, the conjugation for "yo" (I) is the same as the conjugation for "él/ella/usted" (he/she/you formal).

Yo hablaba, Él hablaba
Yo comía, Ella comía

Context or explicitly stating the subject pronoun (e.g., "Yo comía" vs. "Él comía") will clarify who is performing the action if needed.

La Hora del Cuento (Story Time)

Let's reminisce about childhood.

Recuerdos de la Infancia

Cuando yo era (ser - irregular) pequeño/a, vivía en un pueblo cerca del mar. Todos los veranos, mi familia y yo visitábamos la playa.

Yo nadaba en el océano con mis hermanos. Mis padres descansaban en la arena y leían libros. Por las tardes, nosotros comíamos helado.

Mi abuela cocinaba muy bien. Ella siempre preparaba pasteles deliciosos. Nosotros hablábamos mucho y reíamos (reír - to laugh, e:i stem change in some forms, but imperfect regular for -ir).

Era una época muy feliz.

Childhood Memories (Translation)

When I was little, I used to live in a town near the sea. Every summer, my family and I used to visit the beach.

I used to swim in the ocean with my siblings. My parents used to rest on the sand and read books. In the afternoons, we used to eat ice cream.

My grandmother used to cook very well. She always used to prepare delicious cakes. We used to talk a lot and laugh.

It was a very happy time.
