Pretérito perfecto vs pretérito indefinido

Pretérito perfecto vs. pretérito indefinido: the core idea

Both forms talk about the past, but they answer different questions:

• Pretérito perfecto (he trabajado, has ido…) → past with a link to now.
• Pretérito indefinido (trabajé, fuiste…) → past in a closed time block, separate from now.

First question to ask yourself:

• Is this past time still “open” or relevant now? → pretérito perfecto.
• Is this past time totally finished and separate? → pretérito indefinido.

Step 1: Look at the time expression

Most of the time, the time expression tells you which tense you need.

Ask yourself:

• Is the period still in progress? (today, this week, this year…) → pretérito perfecto.
• Is the period clearly finished? (yesterday, last week, in 2019…) → pretérito indefinido.

Step 2: Experience “up to now” vs. experience “back then”

Compare these ideas:

• Experiences in your life up to now → pretérito perfecto.
• Experiences limited to a finished period → pretérito indefinido.

Self-check:

• If you can add “in my life (so far)” → he + participio.
• If you can add “in those years / at that time” → indefinido.

Step 3: Recent action vs. finished action

In Spanish, “recent” is about connection, not only minutes.

Both can be correct. The speaker chooses:

• has + participio → focus on the current result.
• indefinido → focus on the finished action in the past.

Step 4: Connection with the present vs. no connection

This is the “big picture” rule:

• Pretérito perfecto → the past action is relevant now.
• Pretérito indefinido → the past action is just a finished chapter.

Think in “time blocks”:

• Open block (today, this week, this year, my life until now) → perfecto.
• Closed block (yesterday, last month, in 2019, in that job) → indefinido.

Step 5: Forming the pretérito perfecto correctly

Pretérito perfecto = present of “haber” + past participle.

Examples:

• He trabajado mucho esta semana.
• Hemos vivido en tres países hasta ahora.

Careful: do not separate haber and the participle:

• *No he nunca estado en Perú.
• Nunca he estado en Perú.

Step 6: Common irregular participles you need

Many participles are regular, but some are very frequent and irregular.

Typical confusion:

• *devolvido → devuelto
• *describido → descrito

Step 7: Choosing the tense without a clear time word

Sometimes there is no explicit time expression. Then think about the focus:

• Pretérito perfecto → your experience or result up to now.
  • He trabajado en banca y en consultoría. (In my career up to now.)
  • Últimamente he tenido muchos problemas con la conexión.
• Pretérito indefinido → you imagine a specific past moment or period.
  • Trabajé tres años en banca. (That period is finished.)
  • Tuve muchos problemas con la conexión cuando trabajé allí.

Ask yourself:

• “Am I talking about my whole life or career so far?” → perfecto.
• “Am I talking about a concrete past job, project or year?” → indefinido.

Step 8: Typical English–Spanish traps

English often uses the simple past where Spanish uses the pretérito perfecto. Be careful in these cases:

• With today / this morning / this week / this year (still open):
  • EN: I worked a lot this week.
    ES: He trabajado mucho esta semana.
  • EN: I called him this morning.
    ES: Esta mañana lo he llamado.
• With ever / never (life experience up to now):
  • EN: Have you ever worked abroad?
    ES: ¿Has trabajado alguna vez en el extranjero?
  • EN: I’ve never been fired.
    ES: Nunca me han despedido.

Incorrect translations to avoid:

• *Esta semana trabajé mucho. (sounds like the week is already over)
• Esta semana he trabajado mucho. (period still open)

Step 9: Self-check: can I choose the correct tense?

Use this mini checklist when you speak or write:

1. Identify the time period
   • Is it open (today, this week, this year, until now, in my life)? → use pretérito perfecto.
   • Is it closed (yesterday, last week, in 2018, in that job)? → use pretérito indefinido.
2. Ask about the connection
   • Does the past action have a visible result or consequence now? → perfecto.
   • Is it just a finished fact in the past? → indefinido.
3. Check the form
   • Perfecto: haber (he, has, ha…) + participle (trabajado, vivido…).
   • Remember irregulars: abierto, escrito, descrito, vuelto, devuelto, reabierto…

If you can calmly answer these three points, you are using pretérito perfecto and pretérito indefinido like a confident B1 speaker.
