The imperfect looks inside the past
The Spanish imperfect is often taught through English translations:
estudiaba — I was studying / I used to study
vivíamos — we were living / we used to live
hacía frío — it was cold
These translations are useful, but they do not explain the tense. The imperfect is not simply “used to” or “was -ing.” It is an imperfective past viewpoint. It presents a past situation from the inside, without packaging it as a completed whole.
Era tarde.
It was late.
Hacía frío.
It was cold.
Vivíamos en Lima.
We were living in Lima / We used to live in Lima.
The speaker does not put a boundary around the situation. The imperfect creates background, description, habit, ongoingness, or internal perspective.
A durable rule:
The imperfect describes what the past was like, what was going on, or what used to happen, rather than advancing the story as a completed event.
Regular imperfect forms
The imperfect is one of the most regular parts of Spanish conjugation.
For -ar verbs:
| Person | hablar |
|---|---|
| yo | hablaba |
| tú | hablabas |
| él/ella/usted | hablaba |
| nosotros/as | hablábamos |
| vosotros/as | hablabais |
| ellos/ellas/ustedes | hablaban |
For -er and -ir verbs:
| Person | comer | vivir |
|---|---|---|
| yo | comía | vivía |
| tú | comías | vivías |
| él/ella/usted | comía | vivía |
| nosotros/as | comíamos | vivíamos |
| vosotros/as | comíais | vivíais |
| ellos/ellas/ustedes | comían | vivían |
There are only three highly common irregular imperfects:
| Infinitive | Imperfect forms |
|---|---|
| ser | era, eras, era, éramos, erais, eran |
| ir | iba, ibas, iba, íbamos, ibais, iban |
| ver | veía, veías, veía, veíamos, veíais, veían |
The morphology is manageable. The challenge is choosing the tense.
Background description
The imperfect sets scenes:
Era tarde y hacía frío.
It was late and it was cold.
La calle estaba vacía.
The street was empty.
Había mucha gente en la estación.
There were many people in the station.
El cielo estaba gris.
The sky was gray.
These sentences describe the conditions within which events occur. They do not move the plot forward by themselves.
Compare:
Era tarde. Salí de la oficina y tomé un taxi.
It was late. I left the office and took a taxi.
Era sets the background. Salí and tomé advance the narrative.
Ongoing past situations
The imperfect presents actions or states as ongoing at a past reference point:
Estudiaba cuando llamaste.
I was studying when you called.
Dormíamos cuando empezó la tormenta.
We were sleeping when the storm began.
Ana leía en la sala.
Ana was reading in the living room.
The event may have begun before the reference point and continued beyond it. The imperfect does not tell us whether it ended. It opens a window into the middle.
Spanish can also use estar + gerundio in the imperfect:
Estaba leyendo cuando llegaste.
I was reading when you arrived.
This is more explicitly progressive than leía, but both can frame an ongoing past action. The choice depends on focus, verb, rhythm, and context.
Habitual past
The imperfect is the normal tense for repeated or habitual actions in the past:
De niño, jugaba en la calle.
As a child, I used to play in the street.
Íbamos a la playa todos los veranos.
We used to go to the beach every summer.
Mi abuelo leía el periódico cada mañana.
My grandfather read/used to read the newspaper every morning.
Antes trabajaba los sábados.
I used to work on Saturdays.
English may use “used to,” “would,” or the simple past. Spanish uses the imperfect because the action is repeated and not presented as one bounded event.
If you say:
Fui a la playa el sábado.
that is a single bounded event. If you say:
Iba a la playa los sábados.
that is a habitual pattern.
Age, time, and weather
Spanish commonly uses the imperfect for age, clock time, and weather in past descriptions:
Tenía diez años.
I was ten years old.
Eran las ocho.
It was eight o’clock.
Era tarde.
It was late.
Hacía frío.
It was cold.
Llovía.
It was raining.
These are background conditions rather than bounded events. You can use the preterite with weather or time when you bound or event-ify the situation:
Llovió toda la noche.
It rained all night.
La tormenta empezó a las ocho.
The storm began at eight.
The imperfect is the default for setting the scene; the preterite appears when the event is bounded.
Mental states and desires
The imperfect commonly describes past mental states, desires, knowledge, beliefs, and intentions:
Quería hablar contigo.
I wanted to talk with you.
Sabía la respuesta.
I knew the answer.
Pensaba que era fácil.
I thought it was easy.
No entendíamos el problema.
We did not understand the problem.
The preterite often changes the interpretation by bounding the state:
Supe la respuesta.
I found out the answer.
Quise hablar contigo.
I wanted/tried/decided to talk with you, depending on context.
No quise hablar.
I refused to speak.
The imperfect keeps the state open as a condition or background.
Description of people, places, and situations
The imperfect describes what people, places, and situations were like:
La casa era pequeña, pero tenía mucha luz.
The house was small, but it had a lot of light.
Mi profesor era paciente y explicaba todo con claridad.
My teacher was patient and explained everything clearly.
La ciudad tenía menos tráfico entonces.
The city had less traffic then.
These descriptions can include both qualities and habitual behaviors. They create a past world.
If a description is presented as a bounded event or evaluation after the fact, the preterite can appear:
La fiesta fue divertida.
The party was fun.
That packages the party as a completed event and evaluates it as a whole. By contrast:
La fiesta era divertida cuando llegamos.
The party was fun when we arrived.
This looks inside the party at that moment.
Interrupted action
A common pattern pairs imperfect background with a preterite interruption:
Estaba leyendo cuando sonó el teléfono.
I was reading when the phone rang.
Caminábamos por el parque cuando empezó a llover.
We were walking through the park when it started to rain.
Dormía cuando llegaron.
He/she was sleeping when they arrived.
The imperfect does not mean the action was literally interrupted in every case. It means the action was ongoing at the reference point. The preterite event enters as a bounded occurrence.
Common learner errors
Error 1: Using imperfect only for “used to”
The imperfect also describes background, weather, age, time, ongoing action, and mental states:
Era tarde.
Tenía diez años.
Sabía la respuesta.
Error 2: Thinking imperfect means unfinished in real life
Vivíamos en Lima.
This does not prove we still live there or that the living never ended. It presents the situation without focusing on its endpoint.
Error 3: Using preterite for all past actions
Ayer era al supermercado is wrong because ir as a bounded trip needs preterite:
Ayer fui al supermercado.
The imperfect is not a universal past tense; it is a viewpoint.
Error 4: Forgetting that imperfect can describe repeated completed events
Iba al gimnasio todos los días.
Each gym visit may have been completed. The imperfect appears because the sentence describes a habit, not a single bounded visit.
Imperfect does not mean vague or unimportant
Because the preterite advances the plot, learners sometimes treat the imperfect as secondary or vague. That is a mistake. The imperfect often carries the information that makes the story intelligible:
No salimos porque llovía.
We did not go out because it was raining.
No entendí la explicación porque hablaba muy rápido.
I did not understand the explanation because he/she was speaking very fast.
In both cases, the imperfect clause explains the situation behind the event. It is not decorative background; it is causal or interpretive context.
Imperfect and politeness or softening
The imperfect can also soften present-time requests or intentions in some contexts:
Quería preguntarle algo.
I wanted to ask you something.
Venía a recoger el paquete.
I was coming to pick up the package.
Although the form is past, the communicative moment may be present. The speaker uses the imperfect to soften the request or make it less abrupt. This is common in service encounters and polite conversation.
This use does not replace the core past-tense imperfect. It shows the same internal, nonbounded quality being used pragmatically: the request is presented as a background intention rather than a direct demand.
The imperfect can frame expectation
The imperfect often describes what someone expected, intended, or assumed before a later event changed the situation:
Iba a llamarte, pero perdí el teléfono.
I was going to call you, but I lost my phone.
Pensaba quedarme, pero tuve que salir.
I was planning to stay, but I had to leave.
Queríamos comprar la casa, pero era demasiado cara.
We wanted to buy the house, but it was too expensive.
These uses reinforce the core meaning: the imperfect opens a past mental or situational frame. It does not assert completion. That is why it is so useful for interrupted plans and unrealized intentions.
Imperfect and open endpoints
The imperfect leaves endpoints outside the frame:
A las ocho cenábamos.
At eight we were having dinner.
The sentence does not say when dinner started or ended. It places the reader inside the event at eight. If the endpoint matters, Spanish can add it or choose another tense:
Cenamos de ocho a nueve.
We had dinner from eight to nine.
Study checkpoint
When you choose the imperfect, be ready to name the frame: background, habit, description, ongoing action, age, time, weather, mental state, or softened intention. The imperfect is purposeful, not a fallback.
Imperfect with repeated scenes
The imperfect can describe not only repeated actions but repeated scenes:
En verano, la casa siempre estaba llena de primos y hacía calor en todas las habitaciones.
The sentence recreates a recurring past environment. The point is not how many times it happened, but what that past world was like whenever the memory frame opens.
Diagnostic refinement: imperfect does not mean “unfinished in reality”
The imperfect presents a situation without closing it from the viewpoint of the sentence. It does not prove that the situation never ended in real life.
En 2010 vivía en Lima.
In 2010 I lived in Lima.
This sentence does not say whether I still live in Lima. It simply opens a window into 2010. The endpoint is not part of the assertion.
Compare:
| Sentence | Viewpoint |
|---|---|
| Vivía en Lima cuando la conocí. | residence as background |
| Viví en Lima tres años. | residence as bounded completed period |
| Tenía diez años. | age as background at a past point |
| Cumplí diez años en mayo. | birthday as bounded event |
| Quería hablar contigo. | desire as background or softened present request |
| Quise hablar contigo, pero no pude. | attempted/decisive bounded wanting in context |
The imperfect is also common in polite or softened speech because it presents a request, intention, or thought as less abrupt:
Quería preguntarle algo.
I wanted to ask you something.
The speaker may want to ask right now. The imperfect is not lying about past time; it creates pragmatic distance. This use is related to the imperfect’s internal, nonbounded viewpoint: the desire is presented as a background intention rather than a direct demand.
For narrative reading, mark imperfects as scene-building forms. They often supply weather, time, age, emotional state, physical description, habitual context, and ongoing activity. Then look for preterites to see which events move the plot forward.
The learner’s correction is simple: do not translate the imperfect only as “used to” or “was -ing.” Those translations are outputs. The grammar is internal viewpoint.

Final rule
The imperfect presents the past from the inside. It describes background, ongoing situations, habits, age, weather, time, mental states, and what things were like.
Do not define it only as “used to” or “was -ing.” Those are translations, not the grammar. The imperfect is an imperfective viewpoint: it does not package the situation as a completed event.
Use it when you are building the past world rather than moving the story to the next event.
