Learn to distinguish between the pretérito imperfecto and pretérito indefinido to describe past actions like "enseñaba" (I used to teach) and specific events like "suspendió" (he suspended). This lesson clarifies habitual versus completed past actions, essential for expressing nuanced past narratives in Spanish.
  1. The simple past is used for actions that started and finished in the past and to narrate a series of events that happened in the past.
  2. The imperfect past tense is used to describe situations or actions in progress in the past.
  3. The imperfect tense can be used for the background or context, and the simple past for specific actions.

 

Tiempo verbal (Verb tense)Regla (Rule)Ejemplo (Example)
Pretérito IndefinidoUna acción que pasó y terminó en el pasado (An action that happened and ended in the past)Aprobé el máster en 2022 (I passed the master's in 2022)
Pretérito IndefinidoEvento en el pasado (Event in the past)El profesor suspendió la clase por la lluvia (The teacher cancelled the class because of the rain)
Pretérito ImperfectoAcción habitual o repetida en el pasado (Habitual or repeated action in the past)Siempre enseñaba en la escuela primaria (I always taught in primary school)
Pretérito ImperfectoCómo era un lugar o situación en el pasado (How a place or situation was in the past)La escuela era antigua y tenía patio grande (The school was old and had a large playground)
Pretérito Imperfecto + Pretérito IndefinidoEl imperfecto describe la situación y el indefinido dice qué pasó (The imperfect describes the situation and the simple past tells what happened)Mientras veníamos de clase, llamó mi madre (While we were coming from class, my mother called)

Exercise 2: Multiple Choice

Instruction: Choose the correct sentence according to the use of the imperfect past tense or the preterite past tense in each context.

1.
Error: 'jugué' is in preterite, it is not used for habitual actions; the imperfect 'jugaba' should be used.
Error: 'fui' is in preterite indicating a punctual action, but the action is habitual; the imperfect 'era' should be used.
2.
Error: 'tomaban' (imperfect) indicates a habitual action, but here it is a punctual event; the preterite 'tomaron' should be used.
Error: 'explicaba' (imperfect) indicates an action in progress, but here it is a punctual event; the preterite 'explicó' should be used.
3.
Error: 'sonaba' (imperfect) indicates an ongoing action, but the phone rang at a specific moment; the preterite 'sonó' should be used.
Error: 'estudié' (preterite) indicates a finished action, but here it is an ongoing action; the imperfect 'estudiaba' should be used.
4.
Error: 'yesterday' indicates a specific moment, incompatible with 'always' and the imperfect; it should be preterite without 'always'.
Error: 'desayuné' is in preterite, incompatible with 'always' which indicates a habit; the imperfect 'desayunaba' should be used.

Understanding the Past Tenses in Spanish: Pretérito Imperfecto vs. Pretérito Indefinido

This lesson focuses on two important past tenses in Spanish: pretérito imperfecto and pretérito indefinido. Mastering the use of these tenses will help you describe past actions clearly and accurately.

What You Will Learn

  • Pretérito Indefinido: Describes actions that started and finished in the past. It’s used for specific, completed events. Examples: "Aprobé el máster en 2022", "El profesor suspendió la clase por la lluvia."
  • Pretérito Imperfecto: Used to talk about habitual or repeated actions in the past, and to describe past situations or settings. Examples: "Siempre enseñaba en la escuela primaria", "La escuela era antigua y tenía patio grande."
  • Combining both tenses: The imperfect sets the scene or background, while the indefinido gives information about a specific event. Example: "Mientras veníamos de clase, llamó mi madre."

Key Differences and Usage Tips

Pretérito Indefinido is for actions completed in the past, often with a clear start and end. Use it to narrate sequences or single events.

Pretérito Imperfecto describes ongoing or repeated past actions and provides background information, such as what the setting or situation was like.

Often, these tenses work together to tell stories, with imperfect describing the context and indefinido actions happening within it.

Helpful Vocabulary and Expressions

  • acciones terminadas: finished actions
  • acciones habituales: habitual actions
  • situación: situation
  • evento puntual: specific event
  • mientras: while (used to link actions in progress with a single event)

Differences Between English and Spanish Past Tenses

Unlike English, which often uses a simple past tense for all completed past actions, Spanish distinguishes clearly between actions that were completed (pretérito indefinido) and those that were ongoing or habitual (pretérito imperfecto). For example, English might simply say "I studied," but in Spanish, estudié implies a completed action, whereas estudiaba suggests studying over a period or habitually.

Useful phrases include:
Mientras (while) to link an ongoing action with a specific event,
Siempre (always) to signal habitual actions,
Ayer (yesterday) to specify a particular time in the past.

Remember, the context often guides the choice between these two tenses, so paying attention to the surrounding words and time markers is essential.
