Irse in the Preterite Tense — full table

Person Pronoun Form
yo me fui
tú te fuiste
él/ella/Ud. se fue
nosotros/as nos fuimos
vosotros/as os fuisteis
ellos/ellas/Uds. se fueron

Gerund: yendo · Past participle: ido

The gerund is yendo, which you use with estar to say what is happening right now: “Estoy yendo” means the action of irse is in progress at this very moment. The past participle is ido, which you use with haber in the perfect tenses: “he ido” is the present perfect, used for a completed action. Keep both forms in mind as you read the examples below, because the preterite is only one part of how irse is used.

How the preterite of irse is formed

Irse is regular in the preterite tense. Take the stem **** and add the preterite endings for -ir verbs: -fui, -fuiste, -fue, -fuimos, -fuisteis, -fueron, giving fui, fuiste, fue, fuimos, fuisteis, fueron. Watch the accents: the yo form is fui and the él/ella/Ud. form is fue. Because irse is reflexive, put the pronoun before each form: me fui, te fuiste, se fue, nos fuimos, os fuisteis, se fueron.

When to use the preterite of irse

The preterite is not a single-purpose tense. Below are the five situations where you will use irse in the preterite most often. Each one comes with a real example, so read the rule, then say the example out loud.

1. One finished action

The preterite reports a single action that started and finished in the past. The action is done, counted once, and the story moves on. Example: “Ayer, yo me fui de casa temprano.” — Yesterday, I went away from home early.

2. A sequence of events

In a story, each preterite form is one step forward in time. When several things happened one after another, the preterite lists them in order. Example: “Nosotros nos fuimos a Madrid en tren.” — We went away to Madrid by train.

3. A specific time marker

Time words such as ayer, anoche, el año pasado and la semana pasada point to the preterite. They name a finished moment, and the verb must match. Example: “Él se fue sin despedirse de nadie ayer.” — He went away without saying goodbye to anyone yesterday.

4. A sudden change or interruption

The preterite describes sudden changes and interruptions: something happened, and the situation was different afterwards. Example: “Ellos se fueron de viaje el lunes de repente.” — They went away on a trip on Monday suddenly.

5. A completed time frame

When an action took place inside a period of time that is now over, the preterite is the right tense, because the period itself is finished. Example: “Tú te fuiste de casa temprano la semana pasada.” — You went away from home early last week.

Preterite Tense vs Imperfect: how to choose

The closest tense to the preterite is the imperfect, and choosing between them is one of the hardest decisions in Spanish. The rule is simple: the preterite reports one finished action, while the imperfect describes background, habits in the past, or an action that was in progress when something else happened. The three pairs below use the same verb, so the only thing that changes is whether the action is finished and counted, or ongoing and descriptive. Time words help: ayer and de repente point to the preterite, while mientras and todos los días in the past point to the imperfect.

  • Preterite Tense: “Ayer, yo me fui de casa temprano.” — Yesterday, I went away from home early.

  • Imperfect: “Yo me iba de casa temprano cada día.” — I used to go away from home early every day.

  • The preterite sentence reports one finished action; the imperfect sentence describes a habit in the past. Ayer points to the preterite, cada día in the past points to the imperfect.

  • Preterite Tense: “Anoche, él se fue a Madrid en tren.” — Last night, he went away to Madrid by train.

  • Imperfect: “Él se iba a Madrid en tren todos los días.” — He used to go away to Madrid by train every day.

  • Anoche names one finished night, so the preterite is right; todos los días in the past describes a routine, so the imperfect is right.

  • Preterite Tense: “Nosotros nos fuimos sin despedirse de nadie ayer.” — We went away without saying goodbye to anyone yesterday.

  • Imperfect: “Nosotros nos íbamos sin despedirse de nadie cuando éramos jóvenes.” — We used to go away without saying goodbye to anyone when we were young.

  • The preterite sentence counts one finished action; the imperfect sentence describes how things used to be. That difference — finished event versus background — is the whole decision.

Common mistakes with irse in the preterite

These are the errors learners actually make with this verb in this tense. Each one shows the wrong version, the right version, and why the correction matters.

  • Wrong: “Yo fui de casa temprano.” Right: “Yo me fui de casa temprano.” Why: Irse is reflexive, so the pronoun me is required before every form. Without it the sentence is incomplete.

  • Wrong: “Ayer yo í a Madrid en tren.” Right: “Ayer yo fui a Madrid en tren.” Why: Irse has an irregular preterite: the correct first-person form is fui, not the regular í.

  • Wrong: “Nosotros fuiste sin despedirse de nadie.” Right: “Nosotros nos fuimos sin despedirse de nadie.” Why: Nosotros needs nos fuimos. The tú form fuiste belongs with tú.

  • Wrong: “Ellos fui de viaje el lunes.” Right: “Ellos se fueron de viaje el lunes.” Why: The verb must agree with its subject. Ellos needs the ellos form se fueron, not the yo form fui.
