Spanish Past Tenses Compared
English has one simple past tense: "I spoke." Spanish has three main ways to talk about the past, and choosing the wrong one changes the meaning of your sentence. The pretérito indefinido, the imperfecto, and the pretérito perfecto each serve a distinct purpose. This guide shows you exactly when to use each one.
Pretérito Indefinido: Completed Actions
The pretérito is your go-to tense for actions that started and finished at a specific point in the past. It is the tense of events, facts, and completed sequences.
Regular Conjugation
For -ar verbs, the endings are: -é, -aste, -ó, -amos, -asteis, -aron. For -er/-ir verbs: -í, -iste, -ió, -imos, -isteis, -ieron.
When to Use It
- Completed actions: Ayer hablé con mi madre. — Yesterday I spoke with my mother.
- Sequential events: Me levanté, desayuné y salí. — I got up, had breakfast, and left.
- Specific duration: Viví en Madrid tres años. — I lived in Madrid for three years.
- Sudden actions: De repente, sonó el teléfono. — Suddenly, the phone rang.
Key trigger words for pretérito: ayer (yesterday), anoche (last night), la semana pasada (last week), una vez (once), de repente (suddenly). If you see these, the pretérito is almost always correct.
Imperfecto: Ongoing and Habitual Past
The imperfecto describes actions that were ongoing, habitual, or repeated in the past without a defined endpoint. It paints the background of a story.
Regular Conjugation
For -ar verbs: -aba, -abas, -aba, -ábamos, -abais, -aban. For -er/-ir verbs: -ía, -ías, -ía, -íamos, -íais, -ían. Only three verbs are irregular in the imperfecto: ser (era), ir (iba), and ver (veía).
When to Use It
- Habitual actions: Cuando era niño, jugaba en el parque. — When I was a child, I used to play in the park.
- Background descriptions: Llovía y hacía frío. — It was raining and it was cold.
- Age and time: Tenía diez años. — I was ten years old.
- Ongoing states: Quería ser astronauta. — I wanted to be an astronaut.
Trigger words for imperfecto: siempre (always), todos los días (every day), frecuentemente (frequently), mientras (while), cuando era niño (when I was a child). These signal habitual or ongoing past actions.
Using Both Together
The most natural Spanish storytelling combines both tenses. The imperfecto sets the scene; the pretérito delivers the action.
- Yo dormía (imperfecto) cuando sonó (pretérito) el teléfono. — I was sleeping when the phone rang.
- Llovía (imperfecto) cuando salimos (pretérito) de casa. — It was raining when we left the house.
- Mientras ella cocinaba (imperfecto), él llegó (pretérito). — While she was cooking, he arrived.
Think of it like a movie: the imperfecto is the camera panning across a scene, and the pretérito is a cut to a specific moment of action.
Pretérito Perfecto: Recent Past and Present Relevance
The pretérito perfecto (present perfect) is formed with haber + past participle. It connects past actions to the present moment.
When to Use It
- Today or recent actions (especially in Spain): Hoy he comido paella. — Today I have eaten paella.
- Life experiences: ¿Alguna vez has viajado a Japón? — Have you ever traveled to Japan?
- Actions with present consequences: He perdido mis llaves. — I have lost my keys (and still cannot find them).
In Latin America, the pretérito indefinido is often used where Spain would use the perfecto. "Hoy comí paella" (Latin America) vs "Hoy he comido paella" (Spain). Both are correct. When in doubt, the pretérito indefinido is understood everywhere.
Frequently Asked Questions
What is the difference between pretérito and imperfecto?
The pretérito (hablé, comí) describes completed actions with a clear beginning and end. The imperfecto (hablaba, comía) describes ongoing, habitual, or background actions in the past. Think of pretérito as a snapshot and imperfecto as a video.
When should I use the present perfect (he hablado) instead of the pretérito?
In Spain, the present perfect is used for actions that happened today or have relevance to the present moment (Hoy he comido paella). In Latin America, the pretérito is more common in these situations (Hoy comí paella). Both are correct; usage varies by region.
What are trigger words for the pretérito?
Common triggers include: ayer (yesterday), anoche (last night), la semana pasada (last week), el año pasado (last year), una vez (once), de repente (suddenly), and specific dates or times.
What are trigger words for the imperfecto?
Common triggers include: siempre (always), todos los días (every day), frecuentemente (frequently), generalmente (generally), mientras (while), cuando era niño (when I was a child), and de pequeño (as a kid).
Can pretérito and imperfecto appear in the same sentence?
Yes, and this is very common. The imperfecto sets the background scene while the pretérito interrupts with a specific action: "Yo dormía cuando sonó el teléfono" (I was sleeping when the phone rang).
