The pretérito indefinido has one core job: reporting past actions that are completed and bounded — events with a defined start, a defined end, or a temporal limit you can point to. I called Marta yesterday. We lived in Granada for three years. My grandfather was born in 1932. All preterite. Once you internalize the idea of boundedness, the choice between preterite and imperfect stops feeling like a guessing game.
This page covers what "bounded" actually means, the time markers that lock you into the preterite, the contrast with the imperfect, and the peninsular quirk that pushes today's bounded events into the present perfect (he comido) rather than the preterite (comí) — a rule that distinguishes Spain Spanish from Latin American Spanish.
What "bounded" means
A bounded action is one you can mentally put in a box: it started, it happened, it ended. The boundary can be explicit (ayer, en 2010, durante tres horas) or implicit (the speaker treats the event as a single, completed unit). The preterite is the tense for these boxed events.
Ayer comí paella con mi familia.
Yesterday I ate paella with my family.
Estuve dos años en Londres antes de volver a Madrid.
I spent two years in London before coming back to Madrid.
Mi abuelo nació en 1932 y murió en 2018.
My grandfather was born in 1932 and died in 2018.
Notice that estuve dos años en Londres is preterite even though two years is a long stretch. The duration doesn't matter — what matters is that the stay is closed off. He left London; the period is over. If the stay were still ongoing, you'd say llevo dos años en Londres (present tense), not a past form at all.
Time markers that trigger the preterite
Certain time expressions are reliable signals that you want the preterite. Memorize this list — once you see one of these in a sentence, the verb should almost always be in the preterite (with one big exception for Spain, covered below).
- ayer — yesterday
- anteayer — the day before yesterday
- anoche — last night
- el lunes pasado / el martes pasado — last Monday / Tuesday
- la semana pasada — last week
- el mes pasado / el año pasado — last month / year
- en 1995 / en 2010 — in 1995 / 2010
- hace dos años / hace una semana — two years ago / a week ago
- durante + duration — durante tres horas, durante dos meses
- de repente — suddenly
- una vez — once
Anoche cené con Pablo en aquel italiano de la calle Fuencarral.
Last night I had dinner with Pablo at that Italian place on Fuencarral street.
El año pasado viajamos a Italia y nos encantó.
Last year we travelled to Italy and we loved it.
Hace dos años dejé de fumar y desde entonces estoy mucho mejor.
Two years ago I quit smoking and I've been much better since then.
The peninsular twist: today's events take the present perfect
This is where Spain Spanish diverges from Latin American Spanish and from the textbooks written for the American market. In peninsular Spanish, events that happened today — or within the current time frame the speaker mentally inhabits (esta mañana, esta tarde, esta semana, este mes, este año) — typically take the present perfect (he comido), not the preterite (comí).
Hoy he comido paella.
Today I ate paella. (Spain)
Esta mañana he hablado con el médico.
This morning I spoke to the doctor. (Spain)
Este año he viajado mucho por trabajo.
This year I've travelled a lot for work.
A Latin American speaker would say Hoy comí paella, Esta mañana hablé con el médico. In Spain that sounds wrong — or, more precisely, it sounds Latin American. The hodiernal (today-relevant) frame demands the present perfect.
The flip side: the moment you cross out of "today" into a time frame the speaker treats as closed, you switch back to the preterite.
Ayer comí paella, pero hoy he comido pasta.
Yesterday I ate paella, but today I had pasta.
The contrast in one sentence: comí (yesterday, closed) and he comido (today, still inside the current frame).
That said, the distinction is softening. Younger speakers and many regions of Spain (notably parts of Galicia, Asturias, the Canary Islands, and León) use the preterite for today's events without anyone batting an eye. In educated standard Madrid Spanish, though, the present perfect for today is the safer default — and the one you'll see in news writing, formal speech, and exam keys.
Contrast with the imperfect: completed vs. ongoing
The other big past tense, the pretérito imperfecto (hablaba, comía, vivía), is reserved for actions that are not treated as bounded — habitual events, ongoing states, background descriptions, things that used to happen or were happening without a closed-off endpoint.
De pequeño vivía en Bilbao y jugaba al fútbol cada tarde.
As a kid I lived in Bilbao and played football every afternoon.
That whole period of childhood is described as ongoing background — no specific bounded events, just the way things were. Compare:
A los doce años me mudé a Madrid y dejé de jugar al fútbol.
At twelve I moved to Madrid and stopped playing football.
Two specific, bounded events: the move and the stopping. Both preterite.
The acid test: can you replace the English verb with used to or was -ing? Then it's probably imperfect. Can you replace it with a single completed did? Then it's preterite.
Mientras estudiaba en la universidad conocí a tu padre.
While I was studying at university I met your father.
Estudiaba — ongoing background, imperfect. Conocí — bounded event (one specific moment), preterite. This pairing of imperfect-as-background plus preterite-as-event is the engine of Spanish narrative.
Telling a story: preterite drives the plot
When you narrate a sequence of past events, each plot-advancing action takes the preterite. Each preterite verb is one step forward in the story.
Llegué a casa, abrí la nevera, saqué una cerveza y me senté en el sofá.
I got home, opened the fridge, grabbed a beer and sat down on the sofa.
Four bounded events, four preterites. If at any point you want to describe the background — the house was dark, the fridge was empty, I was exhausted — you switch to the imperfect: la casa estaba oscura, la nevera estaba vacía, yo estaba agotado. See verbs/preterite/usage-sequences for the full pattern.
Common Mistakes
❌ Hoy comí paella.
Incorrect for Spain — today's events take the present perfect
✅ Hoy he comido paella.
Today I ate paella. (Spain)
The classic transfer error from English ("today I ate") or from Latin American Spanish ("hoy comí"). In peninsular Spanish, hoy triggers the present perfect.
❌ Cuando era niño, fui a la playa cada verano.
Incorrect — habitual childhood activity needs the imperfect
✅ Cuando era niño, iba a la playa cada verano.
When I was a kid, I went to the beach every summer.
English speakers often default to the preterite because English uses the simple past for both I went yesterday and I went every summer. Spanish forces you to mark the difference: bounded event → preterite, habitual background → imperfect.
❌ Ayer la casa era muy oscura cuando llegué.
Incorrect — description of a state at a moment in time needs the imperfect
✅ Ayer la casa estaba muy oscura cuando llegué.
Yesterday the house was very dark when I got home.
Llegué is the bounded event (the arrival); estaba is the background state at that moment. English speakers learning Spanish frequently push descriptive was/were into the preterite (fue, estuvo) when they should be imperfect (era, estaba).
❌ Viví en Madrid desde 2018.
Incorrect — an ongoing situation that continues into the present needs the present, not the preterite
✅ Vivo en Madrid desde 2018.
I've lived in Madrid since 2018.
If the action is still going on, Spanish uses the present tense (often with desde or desde hace), not any past form. The preterite would mean you no longer live there.
❌ La semana pasada he visto a tus padres.
Incorrect — last week is a closed time frame, so the preterite is needed
✅ La semana pasada vi a tus padres.
I saw your parents last week.
The mirror image of the hoy mistake. Once the time frame is closed (la semana pasada, ayer, en mayo), Spain Spanish locks back into the preterite.
Key takeaways
- The preterite is for bounded, completed past actions — events you can put in a box.
- Time markers like ayer, anoche, la semana pasada, en 1995, hace dos años, durante tres horas trigger the preterite.
- In Spain, today's events take the present perfect, not the preterite (hoy he comido, not hoy comí).
- The preterite contrasts with the imperfect: preterite for bounded events, imperfect for habits, ongoing states, and background description.
- In narrative, the preterite advances the plot while the imperfect paints the background.

- Pretérito vs imperfecto: visión generalA2 — The cardinal aspectual contrast in Spanish past tenses: the preterite frames events as bounded and completed, the imperfect frames them as ongoing, habitual, or descriptive. One of the steepest cliffs for English speakers, because English collapses both into the simple past.
- Cómo elegir entre pretérito y pretérito perfectoA2 — Peninsular Spanish's defining past-tense choice. He comido for actions inside the current time frame (hoy, esta semana, este año, en mi vida); comí for actions outside it (ayer, la semana pasada, hace dos años). Time markers do most of the work. Plus the peninsular vs Latin American contrast and the northern Spain counter-trap.
- Imperfecto para acciones habitualesA2 — The imperfect's bread-and-butter use: things you used to do in the past, things you would do on a regular basis, patterns and routines that repeated themselves. If English would say 'used to' or habitual 'would', Spanish uses the imperfect.
- Pretérito con expresiones temporalesA2 — The time expressions that trigger the preterite in peninsular Spanish — ayer, anoche, hace dos años, en 2010, durante tres horas — and the equally important set that triggers the present perfect instead in Spain.
- Pretérito indefinido: verbos regulares en -arA2 — The regular -ar preterite — endings -é, -aste, -ó, -amos, -asteis, -aron — with obligatory accents, the peninsular vosotros form, and the today/not-today rule that governs when to use it in Spain.
