The imperfect past tense, or pretérito imperfecto in Spanish, is a fundamental tense used to describe actions, events, and states in the past. Unlike the preterite tense, which highlights actions completed at a specific point in time, the imperfect tense describes ongoing, habitual, or incomplete actions. This tense is essential for painting a vivid picture of past activities, setting the scene, or discussing actions that were happening simultaneously with other events.
How to Form the Imperfect Tense
Spanish verbs are conjugated in the imperfect tense based on their endings: -ar, -er, or -ir. Each verb type has a specific set of endings.
Conjugating Regular -ar Verbs
For regular -ar verbs, the endings in the imperfect tense are as follows:
- yo: -aba
- tú: -abas
- él/ella/usted: -aba
- nosotros/nosotras: -ábamos
- vosotros/vosotras: -abais
- ellos/ellas/ustedes: -aban
Example with the verb "hablar" (to speak):
- yo hablaba: I was speaking
- tú hablabas: you were speaking
- él/ella/usted hablaba: he/she/you was/were speaking
- nosotros/nosotras hablábamos: we were speaking
- vosotros/vosotras hablabais: you all were speaking
- ellos/ellas/ustedes hablaban: they/you all were speaking
Conjugating Regular -er and -ir Verbs
Regular -er and -ir verbs share the same set of endings in the imperfect tense:
- yo: -ía
- tú: -ías
- él/ella/usted: -ía
- nosotros/nosotras: -íamos
- vosotros/vosotras: -íais
- ellos/ellas/ustedes: -ían
Examples:
For -er verbs like "comer" (to eat):
- yo comía: I was eating
- tú comías: you were eating
- él/ella/usted comía: he/she/you was/were eating
- nosotros/nosotras comíamos: we were eating
- vosotros/vosotras comíais: you all were eating
- ellos/ellas/ustedes comían: they/you all were eating
For -ir verbs like "vivir" (to live):
- yo vivía: I was living
- tú vivías: you were living
- él/ella/usted vivía: he/she/you was/were living
- nosotros/nosotras vivíamos: we were living
- vosotros/vosotras vivíais: you all were living
- ellos/ellas/ustedes vivían: they/you all were living

Uses of the Imperfect Tense
The imperfect tense is used in various contexts to convey different nuances of past actions:
1. Describing Ongoing Actions
Use the imperfect tense to describe actions that were ongoing or in progress in the past, emphasizing the continuity or duration of the action.
Examples:
- Yo leía un libro mientras llovía. (I was reading a book while it was raining.)
- Ella cocinaba la cena cuando llegué. (She was cooking dinner when I arrived.)
2. Expressing Habitual or Repeated Actions
The imperfect tense is ideal for talking about actions that used to happen regularly or habitually in the past.
Examples:
- Cuando era niño, jugaba al fútbol todos los días. (When I was a child, I used to play soccer every day.)
- Ellos iban a la playa cada verano. (They would go to the beach every summer.)
3. Describing Background Information and Setting the Scene
This tense is commonly used to provide background information, set the scene, or describe the circumstances surrounding an event.
Examples:
- Era un día soleado y todos estaban contentos. (It was a sunny day and everyone was happy.)
- Tenía diez años cuando conocí a mi mejor amigo. (I was ten years old when I met my best friend.)
4. Expressing Simultaneous Actions
Use the imperfect tense to describe two or more actions happening simultaneously in the past.
Examples:
- Mientras yo estudiaba, mi hermano jugaba videojuegos. (While I was studying, my brother was playing video games.)
- Nosotros hablábamos y ellos escuchaban. (We were talking and they were listening.)
5. Describing Mental and Emotional States
The imperfect tense is often used to describe ongoing mental and emotional states in the past.
Examples:
- Estaba triste porque extrañaba a mi familia. (I was sad because I missed my family.)
- Ella pensaba que él no vendría a la fiesta. (She thought he wouldn’t come to the party.)
Differences Between the Imperfect and Preterite Tenses
Understanding the distinctions between the imperfect and preterite tenses is essential for accurately conveying past events in Spanish.
Completion vs. Continuity
The preterite tense emphasizes the completion of an action, while the imperfect tense focuses on its continuity or habitual nature.
Examples:
- Preterite: Ayer terminé mi tarea. (Yesterday I finished my homework.) [Emphasizes completion]
- Imperfect: Siempre hacía mi tarea después de la cena. (I always did my homework after dinner.) [Emphasizes habit]
Specific Time Frame vs. Undefined Time Frame
The preterite tense is used when the action has a specific time frame, whereas the imperfect tense is used when the time frame is undefined or irrelevant.
Examples:
- Preterite: Estudié en la universidad por cuatro años. (I studied at the university for four years.) [Specific time frame]
- Imperfect: Estudiaba mucho cuando era estudiante. (I studied a lot when I was a student.) [Undefined time frame]
Sequence of Events vs. Background Information
The preterite tense is often used to narrate a sequence of events, while the imperfect tense provides background information and sets the scene.
Examples:
- Preterite: Llegué a la fiesta, saludé a mis amigos y comí algo. (I arrived at the party, greeted my friends, and ate something.) [Sequence of events]
- Imperfect: La casa era grande y había mucha gente. (The house was big and there were many people.) [Background information]
Interrupting Actions
When one action is interrupted by another, use the imperfect tense for the ongoing action and the preterite for the interrupting action.
Example:
- Imperfect and Preterite: Yo leía un libro cuando sonó el teléfono. (I was reading a book when the phone rang.) [Leía is the ongoing action, and sonó is the interrupting action]
Practical Applications and Examples
Daily Routines
Describing daily routines in the past often involves the imperfect tense to emphasize habitual actions.
Example:
- Cuando era niño, me levantaba a las siete de la mañana, desayunaba con mi familia y luego iba a la escuela. (When I was a child, I used to get up at seven in the morning, have breakfast with my family, and then go to school.)
Childhood Memories
The imperfect tense is essential for talking about childhood memories and describing what life was like regularly.
Example:
- En mi infancia, vivía en un pequeño pueblo cerca del mar. Mis amigos y yo siempre jugábamos en la playa después de la escuela. (In my childhood, I lived in a small town near the sea. My friends and I always played on the beach after school.)
Describing Past Situations
This tense is ideal for painting a picture of past situations, including descriptions of people, places, and conditions.
Example:
- La casa donde vivíamos era grande y antigua. Tenía un jardín enorme y muchas habitaciones. (The house where we lived was big and old. It had a huge garden and many rooms.)
Common Mistakes with the Imperfect Tense
Learning to use the imperfect tense correctly involves avoiding common pitfalls.
Confusing Imperfect and Preterite
One of the most frequent mistakes is confusing the imperfect with the preterite tense. Remember, the imperfect is for ongoing, habitual, or background actions, while the preterite is for completed actions.
Incorrect: Anoche estudiaba para el examen. (Last night I was studying for the exam.) [Implies ongoing action]
Correct: Anoche estudié para el examen. (Last night I studied for the exam.) [Emphasizes completion]
Incorrect Conjugation of Irregular Verbs
Irregular verbs in the imperfect tense can be tricky. Memorize their forms to use them correctly.
Incorrect: Yo fui (I was) [for "ser"]
Correct: Yo era (I was)
Overusing the Imperfect
Sometimes learners overuse the imperfect tense when the preterite is more appropriate, especially for actions completed at a specific point in time.
Incorrect: Ayer comía una pizza. (Yesterday I was eating a pizza.)
Correct: Ayer comí una pizza. (Yesterday I ate a pizza.)
