Pretérito / Imperfecto

The pretérito (also called the preterite or past simple) is used for actions that are viewed as completed, finished, or bounded in time. When you use the pretérito, you are treating the action as a single event with a definite beginning, end, or both. It answers the question "what happened?" rather than "what was going on?" Use the pretérito for single completed actions: "comí una manzana" (I ate an apple), "ella habló con su madre" (she spoke with her mother), "llegamos a las diez" (we arrived at ten). Use it for actions that happened a specific number of times: "fui tres veces" (I went three times), "lo hice dos veces" (I did it twice). Use it for actions within a stated time frame: "viví en Madrid por dos años" (I lived in Madrid for two years), "estudié toda la noche" (I studied all night). The pretérito is also used for chains of sequential actions that move a narrative forward: "me levanté, desayuné y salí de casa" (I got up, had breakfast, and left the house). Each action is a completed step in a sequence. Think of it as bullet points in a story - one thing happened, then the next, then the next. Time words that often signal the pretérito include: ayer (yesterday), anoche (last night), la semana pasada (last week), una vez (once), de repente (suddenly), and en ese momento (at that moment). These markers point to specific, bounded events.

The imperfecto (imperfect tense) is used for past actions or states that are viewed as ongoing, habitual, or without a defined endpoint. It describes what was happening, what used to happen, or what things were like. Rather than capturing a single completed event, the imperfecto paints a picture of the background, the setting, and the ongoing conditions of the past. Use the imperfecto for habitual or repeated past actions: "cuando era niño, jugaba en el parque" (when I was a child, I used to play in the park), "siempre comíamos a las dos" (we always ate at two o'clock). Use it for ongoing past actions or states without a specified end: "llovía mucho" (it was raining a lot), "ella tenía el pelo largo" (she had long hair). Use it for background descriptions and scene-setting: "era un día bonito, el sol brillaba y los pájaros cantaban" (it was a beautiful day, the sun was shining and the birds were singing). The imperfecto is also essential for describing age, time, weather, emotions, and physical states in the past: "tenía diez años" (I was ten years old), "eran las tres de la tarde" (it was three in the afternoon), "hacía mucho calor" (it was very hot), "estaba triste" (I was sad). These are conditions that existed as backgrounds to other events. Key time words for the imperfecto include: siempre (always), todos los días (every day), a menudo (often), generalmente (generally), mientras (while), de niño/a (as a child), and cada verano (every summer). These expressions indicate repetition or ongoing conditions rather than single events.

Regular pretérito conjugation follows predictable patterns based on the verb ending. For -AR verbs (like hablar): yo hablé, tú hablaste, él habló, nosotros hablamos, vosotros hablasteis, ellos hablaron. For -ER and -IR verbs (like comer, vivir): yo comí/viví, tú comiste/viviste, él comió/vivió, nosotros comimos/vivimos, vosotros comisteis/vivisteis, ellos comieron/vivieron. Note the accent marks on the yo and él/ella forms - they are essential for correct spelling and pronunciation. The imperfecto is actually easier to conjugate because there are only three irregular verbs in the entire tense: ser, ir, and ver. For regular -AR verbs: yo hablaba, tú hablabas, él hablaba, nosotros hablábamos, vosotros hablabais, ellos hablaban. For -ER and -IR verbs: yo comía/vivía, tú comías/vivías, él comía/vivía, nosotros comíamos/vivíamos, vosotros comíais/vivíais, ellos comían/vivían. The -AR imperfect ending -aba is one of the most recognizable sounds in Spanish. The three irregular imperfecto verbs are: ser (era, eras, era, éramos, erais, eran), ir (iba, ibas, iba, íbamos, ibais, iban), and ver (veía, veías, veía, veíamos, veíais, veían). Meanwhile, the pretérito has many irregular verbs including ser/ir (fui, fuiste, fue, fuimos, fuisteis, fueron - yes, ser and ir share identical preterite forms), hacer (hice, hiciste, hizo...), tener (tuve, tuviste, tuvo...), and estar (estuve, estuviste, estuvo...). The large number of irregular preterite forms is one reason this tense requires more practice time to master.

The real mastery of pretérito and imperfecto comes when you use them together in narration, which is exactly how native speakers tell stories. The imperfecto sets the stage by describing what was going on, and the pretérito moves the story forward by introducing completed actions that interrupt or change the scene. This interplay is the engine of storytelling in Spanish. Consider this example: "Caminaba por la calle cuando vi a mi amigo" (I was walking down the street when I saw my friend). Here, "caminaba" (imperfecto) describes the ongoing background action - the walking that was already in progress. "Vi" (pretérito) introduces the completed interrupting action - the moment of seeing the friend. The imperfecto is the movie playing in the background; the pretérito is the event that happens within it. Another example: "Cuando era joven, vivía en Barcelona. Un día, decidí mudarme a Madrid" (When I was young, I lived in Barcelona. One day, I decided to move to Madrid). The imperfecto describes the ongoing state of being young and the habitual state of living in Barcelona. The pretérito marks the specific, completed decision to move. You can feel how the narrative shifts from painting a picture to advancing the plot. A common mistake is using the pretérito for everything, which makes stories sound like a flat list of events without any atmosphere or context. Equally problematic is using the imperfecto for everything, which creates a story that never actually moves forward. The beauty of Spanish narration lies in the constant weaving between these two tenses. Songs are particularly effective for developing this skill because lyrics naturally shift between scene-setting (imperfecto) and key narrative moments (pretérito), and the musical rhythm helps you feel the transitions intuitively.
