Understanding the Preterite and Imperfect Tenses in Spanish

Spanish verbs have two primary past tenses to describe actions that occurred in the past: the preterite (pretérito) and the imperfect (imperfecto). Both tenses refer to past events but serve different grammatical and contextual purposes.

What is the Preterite Tense?

The preterite tense is used to describe actions that are completed at a specific point in the past. It denotes definite beginnings or endings and events that happened once or a limited number of times.

• Completed actions: “Ayer comí una manzana.” (Yesterday I ate an apple.)
• Actions with a clear time frame: “Viví en Madrid por dos años.” (I lived in Madrid for two years.)
• Sequential actions: “Me levanté, me vestí, y salí.” (I got up, got dressed, and left.)

What is the Imperfect Tense?

The imperfect tense describes ongoing or habitual past actions without a specified endpoint. It is used to set scenes, describe conditions, or talk about repeated actions in the past.

• Habitual actions: “Cuando era niño, jugaba al fútbol.” (When I was a child, I used to play soccer.)
• Background descriptions: “La casa era grande y tenía un jardín.” (The house was big and had a garden.)
• Ongoing past actions: “Estaba leyendo cuando llamaste.” (I was reading when you called.)

Key Differences Between Preterite vs Imperfect Spanish

Understanding when to use the preterite versus the imperfect can be tricky, but focusing on their distinctive functions helps clarify their usage.

1. Completion vs Continuity

The preterite signals that an action has been completed, while the imperfect suggests an action was ongoing or repeated in the past.

• Preterite: “Terminé el proyecto.” (I finished the project.)
• Imperfect: “Trabajaba en el proyecto.” (I was working on the project.)

2. Specific Time Frame vs Indefinite Time

The preterite is used when the time frame is specified or implied, whereas the imperfect describes actions without a clear beginning or end.

• Preterite: “Llegó a las ocho.” (He arrived at eight.)
• Imperfect: “Llegaba tarde a menudo.” (He often arrived late.)

3. Single vs Repeated Actions

Preterite verbs express single, completed events. Imperfect verbs describe habitual or repeated actions in the past.

• Preterite: “Fui al cine una vez.” (I went to the cinema once.)
• Imperfect: “Iba al cine todos los sábados.” (I used to go to the cinema every Saturday.)

Common Mistakes When Using Preterite and Imperfect and How to Avoid Them

Understanding typical pitfalls helps learners avoid errors and improve accuracy.

• Using preterite for habitual actions: Saying “Cada día comí cereal” instead of “Cada día comía cereal.”
• Using imperfect for completed actions: Saying “Ayer iba al mercado” instead of “Ayer fui al mercado.”
