Pretérito perfecto vs pretérito indefinido

Pretérito perfecto vs. pretérito indefinido: the decision in 10 seconds

• Pretérito perfecto = past event with a live link to “now” (result matters now, or time period is still open).
• Pretérito indefinido = past event in a closed, finished time (storytelling / “done and over”).

Quick self-check: If you can naturally add “and this is relevant now” → use perfecto. If you hear “that’s finished” → use indefinido.

What “connection to the present” really means (what students often miss)

• Not about “how long ago” something happened.
• It’s about whether the speaker treats the situation as still current.
• Often the link is the time window: today / this week / this month / lately are usually “open” windows.

The “time markers” that almost decide for you

• Perfecto triggers (typical): hoy, esta semana, este mes, últimamente, ya, todavía no, nunca, alguna vez, hasta ahora.
• Indefinido triggers (typical): ayer, anteayer, la semana pasada, el año pasado, en 2019, hace dos días, el lunes (specific past Monday).

Professional context tip: In meetings, reports, and updates, speakers often use perfecto to emphasize current status: “Esta semana hemos avanzado…”

Same idea, different meaning: “never” and “experience”

• Perfecto for life experience up to now (your “CV so far”):
  Nunca he estado en Valencia. (Up to now in my life)
• Indefinido for a finished period in the past:
  Nunca estuve en Valencia en 2018. (Only talking about 2018)

Self-check: Are you talking about your whole life up to now or a finished chapter?

“Hace media hora…”: why both tenses can appear

• Pretérito perfecto when the speaker frames it as recent / still relevant now:
  Hace media hora que se ha ido. (He left 30 minutes ago; we feel it as “recent/current”)
• Pretérito indefinido when the speaker frames it as a completed event in a closed past context:
  Ayer por la tarde, hace media hora que se fue. (Yesterday afternoon is closed)

Practical rule: If you add a closed past frame like ayer, la semana pasada, en 2022, you will almost always need indefinido.

Spain vs. Latin America (so you don’t get confused)

• In Spain, it’s very common to use pretérito perfecto with hoy, esta semana, etc. (if the period isn’t finished).
• In many parts of Latin America, speakers often prefer indefinido even with hoy: Hoy firmé el contrato.

For this course: follow the book’s logic (Spain-style contrast): hoy/esta semana → usually perfecto.

Form you should recognize fast (not to memorize slowly)

• Pretérito perfecto = haber (he/has/ha/hemos/habéis/han) + participio.
  he trabajado, han subido, hemos negociado
• Indefinido = one-word past form.
  trabajé, subieron, encontré

Irregular participles you’ll actually meet at work

• reabrir → reabierto (La empresa ha reabierto la negociación.)
• describir → descrito (El informe ha descrito los riesgos.)
• devolver → devuelto (Aún no he devuelto el contrato firmado.)

Common mistake to avoid: he devolvido → he devuelto.

Mini checklist before you speak (self-correction)

1. Find the time frame: Is it open (today/this week) or closed (yesterday/last year)?
2. Ask about relevance: Is the result still important now?
3. Choose: open/relevant → perfecto; closed/story → indefinido.
4. Scan for “trap words”: la semana pasada, en 2022 = almost always indefinido.

Goal for B1: make the choice quickly and consistently; native-like nuance comes later.
