How we look at the past
IMPERFECTO
Inside a situation
INDEFINIDO
A whole event
01 · The core idea

Two ways of looking at the past

The difference is about viewpoint — not simply how long an action lasted.

Compare the same verb
Cuando tenía 20 años, vivía en Madrid.
A description of a situation in the past.
Key point: Imperfecto ≠ long action. Indefinido ≠ short action.
02 · States and experiences

Tenía / Tuve

Same verb — but the speaker frames the past differently.

Imperfecto
Tenía hambre cuando llegué a casa.
I was hungry when I got home.
A state at a particular moment.
Indefinido
Ayer tuve hambre toda la tarde.
I was hungry all afternoon yesterday.
The episode is presented as a whole.
Imperfecto
Cuando lo conocí, tenía dos hijos.
He had two children at that time.
A family situation in the background.
Indefinido
Entre 2010 y 2015 tuvo dos hijos.
He had two children between 2010 and 2015.
Two births / the outcome of a period.

Neither tense tells us whether the children are alive today.

03 · Describing situations

Era / Fue · Estaba / Estuvo

The situation may be the same; the perspective changes.

Imperfecto
De joven, era famoso.
He was famous when he was young.
A description of that stage of life.
Indefinido
Fue famoso durante los años noventa.
He was famous in the 1990s.
A period of fame seen as a complete unit.
Imperfecto
Cuando llegué, Ana estaba enferma.
Ana was ill when I arrived.
Her condition at that moment.
Indefinido
Ana estuvo enferma dos semanas.
Ana was ill for two weeks.
A bounded episode of illness.

Important: Fue famoso does not, by itself, mean “he is no longer famous.”

04 · Strong meaning contrasts

Sabía / Supe · Conocía / Conocí

With some verbs, the perfective viewpoint often highlights the moment a new state begins.

Imperfecto
Sabía la verdad.
I knew the truth.
An existing state of knowledge.
Indefinido
Ayer supe la verdad.
I found out the truth yesterday.
The moment of finding out.
Imperfecto
Conocía a Lucía.
I knew Lucía.
An existing relationship.
Indefinido
Conocí a Lucía en 2022.
I met Lucía in 2022.
The event of meeting her.
Known state vs. the event of discovering / meeting.
05 · Ability and intention

Podía / Pude · No quería / No quise

The indefinido often refers to a particular attempt, outcome or decision.

Imperfecto
De niño, podía correr muy rápido.
I could run very fast as a child.
An ability in the past.
Indefinido
Por fin pude abrir la puerta.
I finally managed to open the door.
Successful outcome in this context.
Imperfecto
No quería firmar el documento.
I didn't want to sign the document.
My attitude / intention.
Indefinido
Al final, no quise firmarlo.
In the end, I refused / decided not to sign it.
A specific decision in this context.
These translations are typical contextual interpretations, not fixed rules for every occurrence of pude or quise.
06 · Thoughts and beliefs

Pensaba que… / Pensé que…

Both can translate as “I thought”, but the viewpoint is different.

Imperfecto
Pensaba que vivías en Chile.
I had this idea / belief.
“I thought you lived in Chile.”
A belief that existed in the past; we view it from the inside.
Indefinido
Cuando vi la puerta cerrada, pensé que te habías ido.
Something made me think this.
“When I saw the closed door, I thought you had left.”
A thought arising at a particular moment.

Ask your students

Does pensé necessarily mean “I changed my mind later”?

No. The tense alone does not tell us whether the belief was later corrected.
07 · A common mistake

Time words do not choose the tense

Ayer, siempre and durante… are clues, not automatic rules.

Both sentences contain “ayer”
Ayer, a las ocho, estudiaba en la biblioteca.
At 8 o’clock, the studying was in progress. We are inside the situation.
Both sentences contain “ayer”
Ayer estudié en la biblioteca.
I present yesterday’s studying as an event / a whole activity.
A habitual perspective
De pequeño, siempre iba al colegio en autobús.
A repeated habit in an open background period.
A bounded period seen as a whole
Durante aquellos tres años, siempre fui al colegio en autobús.
A summary of the repeated routine across a defined three-year period.
Ask: “How is the speaker presenting the past?”
Not: “Which time word do I see?”
08 · Storytelling

Background + Event

The imperfecto sets the scene; the indefinido moves the story forward.

BackgroundEvent
estaba durmiendosonó
Estaba durmiendo cuando sonó el teléfono.
Imperfecto

Estaba durmiendo.
What was happening?

Indefinido

Sonó el teléfono.
What happened?

Reveal the two layers step by step.
09 · Story structure

Simultaneous actions vs. Sequence

Two common ways to connect past actions.

Two ongoing actions
Mientras mi madre cocinaba, yo estudiaba.
Two situations happening at the same time. Both are shown as ongoing background actions.
Sequence of events
Me levanté, desayuné y salí.
One event after another. Each action is presented as a completed step in the story.
A sentence with mientras does not always require two imperfectos. The choice still depends on viewpoint and context.
