What the preterite is and when to use it
The preterite (pretérito indefinido) is a simple past tense in Spanish that describes completed actions at a definite point in time. Unlike the imperfect, which sets scenes or ongoing backgrounds, the preterite focuses on finished events. It maps cleanly to English simple past: "I walked," "she arrived," "they decided." Clear time markers—such as ayer, anoche, el lunes, or el 2019—often appear in preterite sentences, though context can also make the timing clear. Mastering when to narrate actions as completed is central to accurate past storytelling in Spanish.
Core conjugation patterns for regular verbs
Regular -ar, -er, and -ir verbs follow predictable endings in the preterite. For -ar verbs like hablar and estudiar, endings are -é, -aste, -ó, -amos, -asteis, -aron. For -er and -ir verbs like comer and vivir, the endings are -í, -iste, -ió, -imos, -isteis, -ieron. Practice these patterns with common verbs until they become automatic, because these forms are the foundation for everyday past narration.

Irregular stems you will use every day
Many common verbs change their stems in the preterite. For example, -car/-gar/-zar verbs adjust spelling to preserve sound: buscar (busqué), pagar (pagué), cruzar (crucé). Verbs like decir (dije), tener (tuve), and salir (salí) have entirely irregular stems. Verbs of known origin, such as estar (estuve), poder (pude), and saber (supe), are best learned in context. Prioritize these irregulars early, since they appear in high-frequency sentences.

Preterite versus imperfect: quick distinctions
Choosing between preterite and imperfect is a common challenge. Use the preterite for single, completed events with clear endpoints. Use the imperfect for ongoing actions, habits, or background context in the past. Time and completion are the best signals: definite time phrases (ayer, la semana pasada) typically pair with preterite, while descriptions or repeated actions favor imperfect.

Practical tips for building preterite sentences
Build reliable preterite sentences by anchoring them to a clear time frame and a single completed action. Start with subjects and conjugate the verb first, then add context. Listen for past-time adverbs in speech and texts; they are reliable indicators of the preterite. With irregular verbs, create flashcards that pair the stem change with a short sentence so forms stick in memory. Over time, narrating your recent day in preterite will feel natural and accurate.
Common mistakes and how to avoid them
Learners sometimes overuse the preterite where the imperfect is required, especially for background description or repeated actions. Conversely, using the imperfect where a clear endpoint exists can make narratives sound vague. To avoid these errors, ask whether the action is finished and tied to a specific moment. If yes, the preterite is usually correct. Drill short contrasting pairs—such as "Ayer llovió" versus "Llovía mucho aquel verano"—to sharpen your choice between completed and ongoing past situations.
Wrapping up
The preterite is essential for saying that actions happened and finished in the past. By learning core conjugations, recognizing irregular stems, and practicing with clear time markers, you can form accurate, natural-sounding sentences. Use comparison cues and quick checks for completion to choose between preterite and imperfect. With consistent practice, describing past events in Spanish will become precise and automatic.
