Use the preterite for past events you present as complete, and the imperfect for background, descriptions, and situations in progress. When telling a story, you’ll often need both because viewpoint matters as much as when something happened.
English doesn’t always make this distinction clear, so translating “I walked” or “I was” word for word can mislead you. Start by separating your story’s events from the circumstances surrounding them.
Key Takeaways
- Choose the preterite when presenting an action or experience as a complete event.
- Use the imperfect to describe the setting or what was happening at the relevant moment.
- Both tenses can describe the same situation from different viewpoints, so choose your intended meaning before choosing the verb form.
Preterite vs Imperfect: Events and Background
The difference concerns how you present the past. BaseLang’s tense comparison distinguishes what happened from what was going on around it.
Use the preterite for completed events
Compré un billete y subí al tren.
“I bought a ticket and boarded the train.”
Both compré and subí present complete events. First came the purchase; boarding followed. Together, they move the narrative forward.
The preterite doesn’t require a quick action. An experience lasting several years can also take the preterite when you present the whole period as complete. What matters is the boundary you give the experience, not its length.
Use the imperfect for the surrounding situation
Hacía frío y había mucha gente en la estación.
“It was cold, and there were many people at the station.”
Here, hacía and había describe the conditions surrounding the events. They don’t introduce a sequence of completed steps.
The imperfect also describes an activity in progress: Esperaba el tren means “I was waiting for the train.” The sentence places you inside the waiting period without stating its endpoint.
Follow Both Tenses Through a Short Travel Story
A short narrative can establish the scene, then move through several events:
Era temprano y hacía frío. En la estación había mucha gente. Yo llevaba una mochila azul. Compré un billete y busqué mi tren. Después subí y encontré mi asiento.
“It was early, and it was cold. There were many people at the station. I was carrying a blue backpack. I bought a ticket and looked for my train. Then I boarded and found my seat.”
Notice what establishes the scene
Era, hacía, había, and llevaba are imperfect forms. They establish the time, weather, crowd, and what the narrator was carrying.
These details belong to the same setting. Their order doesn’t tell us that one finished before another began. Moving the backpack description earlier would change the emphasis, but not the sequence of events.
Follow the completed actions
Compré, busqué, subí, and encontré are preterite forms. They report the actions as complete parts of the journey.
Notice that busqué mi tren presents the search as an event. It doesn’t itself say whether the search succeeded. The later phrase encontré mi asiento reports a successful result.
The tenses work together: the imperfect gives circumstances, while the preterite carries the narrator through the station and onto the train.
Describe Feelings and Events in a Personal Experience
Personal experiences often need emotional context alongside actions. You can describe how someone felt without making every sentence a completed event.
Give feelings and surroundings their place
Mi primer día en la oficina, estaba nerviosa. No conocía a nadie. La oficina era pequeña y las ventanas estaban abiertas.
“On my first day at the office, I was nervous. I didn’t know anyone. The office was small, and the windows were open.”
Estaba, conocía, era, and estaban establish the narrator’s situation. They describe feelings, knowledge, characteristics, and conditions at that point.
Also, choosing the tense doesn’t replace choosing the right verb. Era pequeña describes a characteristic, while estaban abiertas describes a condition. Our guide to ser and estar in context explains that separate distinction.
Add the events that shaped the experience
Una compañera me saludó y me enseñó mi mesa. Después hablamos unos minutos.
“A colleague greeted me and showed me my desk. Then we talked for a few minutes.”
Saludó, enseñó, and hablamos present complete events. The conversation takes the preterite because the narrator presents it as a whole exchange.
Together, the passages describe both the experience and why it felt significant: the narrator started out nervous, then received a welcome.
Choose the Perspective Before the Tense
Sometimes both tenses are grammatical, but they direct attention differently. Compare these sentences:
Viví en Madrid durante tres años.
“I lived in Madrid for three years.”
En aquella época, vivía en Madrid.
“At that time, I was living in Madrid.”
The first sentence presents a complete three-year period. The second places the speaker inside that period as background to something else.
Both can describe the same person’s life. The imperfect sentence doesn’t tell us when the Madrid period ended because that endpoint isn’t its focus.
An imperfect verb leaves the endpoint outside the sentence. It doesn’t mean the situation continued forever.
This focus on viewpoint also appears in Deliberate Spanish’s storytelling explanation, which contrasts the events receiving attention with the surrounding scene.
Before choosing a tense, decide whether you’re reporting the experience as a complete unit or describing the situation at a particular point. That decision is more useful than guessing whether the action felt “long.”
Avoid These Common Learner Mistakes
Several familiar shortcuts work only part of the time. The complete sentence gives you better guidance than an isolated English word.
Don’t translate every English past tense literally
English “was” can describe many different things:
La habitación era pequeña.
“The room was small.”
La visita fue breve.
“The visit was brief.”
Era describes the room as background. Fue evaluates the visit as a complete experience.
Likewise, English doesn’t always need “was doing” where Spanish uses the imperfect. Llevaba una mochila can translate naturally as either “I was carrying a backpack” or “I had a backpack with me.”
Translate the intended situation, rather than matching each English word to a Spanish form.
Don’t let time words decide everything
Ayer means “yesterday,” but it doesn’t automatically require the preterite.
Ayer hacía frío.
“It was cold yesterday.”
Ayer compré un abrigo.
“I bought a coat yesterday.”
The first sentence describes conditions. The second reports a completed purchase, consistent with the event-based explanation in Vamos Spanish’s preterite guide.
Time expressions help locate your story. However, the verb’s role within that story still determines how you present the action or situation.
Practice With Short Story Prompts
Choose the form that matches the intended meaning. Say each complete sentence aloud before reading the answers.
- Describe the conditions: La estación ___ llena y ___ mucho calor. Use estar and hacer. “The station was full, and it was very hot.”
- Report two completed events: Ayer ___ un billete y ___ al tren. Use comprar and subir. “Yesterday I bought a ticket and boarded the train.”
- Establish an activity in progress: Mientras ___ el tren, miraba el reloj. Use esperar. “While I was waiting for the train, I was looking at the clock.”
Answers and explanations
For the first prompt, use estaba and hacía. Both imperfect forms describe conditions: La estación estaba llena y hacía mucho calor.
The second takes compré and subí because it reports completed events: Ayer compré un billete y subí al tren.
For the third, choose esperaba. Both activities appear in progress: Mientras esperaba el tren, miraba el reloj. The sentence doesn’t report their completion.
Turn the sentences into a personal account
Next, describe an actual journey or first day you remember. Begin with the setting, add how you felt, then report what happened.
Keep your vocabulary familiar so tense choice gets your attention. Afterward, change one detail and retell the account without reading.

Frequently Asked Questions
What are these tenses called in Spanish?
The preterite is commonly called the pretérito indefinido or pretérito perfecto simple. The imperfect is the pretérito imperfecto.
Recognizing these names helps when a textbook, lesson, or exercise uses Spanish terminology. The different names for the preterite don’t indicate different tenses.
Is estaba estudiando an imperfect form?
Yes. Estaba is the imperfect of estar, and estaba estudiando means “I was studying.” The construction explicitly presents studying as an activity in progress.
However, estudiaba can also mean “I was studying” in context. You don’t need to copy the English progressive construction every time English uses an “-ing” form.
Should I choose the tense before conjugating?
Yes. First decide how you want to present the situation, then form the verb. Otherwise, a familiar conjugation can lead you toward a meaning you didn’t intend.
When reviewing an error, keep both the corrected sentence and its meaning. A verb ending alone won’t explain the choice.
Tell the Events and Keep the Context
A clear Spanish story gives the listener both events and context. The preterite presents complete actions or experiences, while the imperfect describes the surrounding situation or an activity in progress.
Start with a short experience you know well. Decide which details establish the scene and which actions move the account forward. Your tense choices will become easier when each sentence has a clear job.
