El Pretérito Indefinido (Preterite): Regular Verbs
Might help first: Ch. 20 — Verb Conjugation System: Overview & Regular Verbs, Ch. 22 — Present Tense: Regular -AR/-ER/-IR Verbs (a suggestion, never a requirement)
Spanish splits the simple past into two different tenses with two different jobs, and the preterite — el pretérito indefinido — is the one that reports a completed event: something that happened, started, or ended at a specific point, viewed as a finished whole rather than a backdrop or a habit. Chapter 22 already showed the present tense stretching to cover “yesterday” informally in casual narration; the preterite is the tense that does this job properly, on purpose, every time you need to say what happened. This chapter covers the full regular paradigm — every verb whose preterite you can build from a completely predictable rule — plus a set of verbs that only look irregular on the page because Spanish spelling has to work around them. The genuinely irregular verbs, the ones that change their actual stem, get their own chapter next.
Core Pattern: The Regular Preterite Endings
What the preterite means: a finished action
A1The single most useful idea to hold onto in this whole chapter: the preterite reports an action with a clear edge — a beginning, an end, or both — treated as a complete, closed event, not an ongoing state or a repeated habit.
Ayer hablé con mi hermana.
Yesterday I talked with my sister.
Viví en Sevilla durante tres años.
I lived in Seville for three years.
Don’t let “finished” mislead you into thinking the preterite is only for short or instant actions — viví… durante tres años is a completed three-year span, reported as one bounded block. The competing past tense, the imperfect (ongoing background, habitual action, description — Chapter 28), is the one reserved for actions without that clear edge. This chapter doesn’t need that contrast to make sense on its own — full treatment of choosing between the two lives in Chapter 29 — but it’s worth knowing from the start that “completed, bounded event” is the preterite’s entire job description.
Hablar: the model -AR verb
A1No boot outline here, same as the regular present-tense tables in Chapter 22 — every form is built the same predictable way, stem habl- plus one of six endings, so there’s no irregular cluster to trace. Notice the two forms that carry a written accent: hablé (yo) and habló (él/ella/usted). That accent isn’t decorative — it marks exactly the two forms most likely to be confused with a different tense, which the Nuance section below comes back to.
Hablé con el director esta mañana.
I talked with the director this morning.
¿Compraste el regalo ayer?
Did you buy the gift yesterday?
Comer and vivir: -ER and -IR share one ending set
A1Comimos paella el domingo pasado.
We ate paella last Sunday.
Vivieron en Madrid antes de mudarse a Barcelona.
They lived in Madrid before moving to Barcelona.
Building Out: Spelling Changes That Keep the Sound
The verbs in this section are not irregular in any real sense — their stem never changes, and the endings above still apply exactly as written. What changes is a single letter, and only ever to keep the spelling honest about how the word actually sounds. This is the same kind of “regular under the hood” adjustment Chapter 2 showed for plurals like lápiz → lápices and Chapter 9 showed for apocope like bueno → buen — a spelling rule reacting to a sound, not a break in the underlying pattern.
-car, -gar, -zar verbs: a yo-form spelling swap
A2Spanish spelling ties the letters c and g to different sounds depending on the vowel that follows them. The regular yo-ending -é starts with e, and ce/ge would sound wrong for these stems — so the spelling swaps in a letter that keeps the original sound intact, purely in the yo form:
- -car → -qué: buscar → busqué (the rest is regular: buscaste, buscó, buscamos, buscasteis, buscaron)
- -gar → -gué: llegar → llegué (llegaste, llegó, llegamos, llegasteis, llegaron)
- -zar → -cé: empezar → empecé (empezaste, empezó, empezamos, empezasteis, empezaron)
Only one of the six cells is actually different from the plain regular pattern — the same single-cell shape Chapter 23 showed for present-tense yo-irregulars like hago. Every other verb in this family works the same way: tocar → toqué, sacar → saqué, explicar → expliqué, jugar → jugué, pagar → pagué, entregar → entregué, cruzar → crucé, comenzar → comencé, almorzar → almorcé.
Busqué las llaves por toda la casa.
I looked for the keys all over the house.
Empecé a estudiar español el año pasado.
I started studying Spanish last year.
When unstressed i becomes y between vowels
A2A second, unrelated spelling rule: when an -er or -ir verb’s stem itself ends in a vowel, the regular -ió/-ieron endings would put an unstressed i directly between two other vowels, which Spanish spelling doesn’t allow — that i becomes a y instead.
Here the affected cells are él/ella/usted and ellos/ellas/ustedes — a different two-cell shape from the single-cell busqué pattern above, because this rule only ever fires where the ending’s i actually lands between two vowels, which happens in exactly those two forms (le-ió → leyó, le-ieron → leyeron). The yo/tú/nosotros/vosotros forms keep their i, and — because a stressed í right after another vowel is a genuine hiatus — that i keeps its written accent: leí, leíste, leímos, leísteis.
The same pattern covers creer (creí, creíste, creyó, creímos, creísteis, creyeron), oír (oí, oíste, oyó, oímos, oísteis, oyeron), and caer (caí, caíste, cayó, caímos, caísteis, cayeron), and it extends to -uir verbs like construir and destruir as well (construí, construiste, construyó…).
Leí ese libro el verano pasado.
I read that book last summer.
No oyeron la alarma.
They didn't hear the alarm.
Nuance, Exceptions & Contrast
-AR and -ER stem-changing verbs: fully regular in the preterite
B1Chapter 23 taught a family of present-tense “boot” verbs whose stressed stem vowel shifts — pensar → pienso, volver → vuelvo. A very natural, very common mistake is assuming that shift carries into the preterite. For -ar and -er verbs, it never does:
Pensó mucho antes de responder, no pensó → piensó.
He thought a lot before answering.
Volvimos a casa tarde.
We went back home late.
Every -ar and -er stem-changing verb from Chapter 23 — pensar, cerrar, entender, perder, volver, contar, poder (poder’s preterite is a separate, genuinely irregular story — see Chapter 27) — drops its present-tense stem change completely once you’re in the preterite and simply follows the regular pattern above.
A common mix-up: present vs. preterite accent marks
A2Because the only visible difference between some present and preterite forms is a single accent mark, this is a genuinely easy typo to make — and a genuinely important one, since it changes the tense entirely:
Hablo español todos los días. / Habló español en la reunión.
I speak Spanish every day. / He spoke Spanish at the meeting.
Bringing It Together
Ayer busqué trabajo toda la mañana. Empecé temprano, leí varios anuncios y llamé a dos empresas. Por la tarde comí con un amigo y hablamos del tema durante horas.
Yesterday I looked for work all morning. I started early, read several listings, and called two companies. In the afternoon I ate with a friend and we talked about it for hours.
Faced with a new verb in the preterite, the regular pattern covers it completely unless the stem itself changes — check first whether it ends in -car/-gar/-zar (a yo-only spelling swap) or has a vowel-final stem (an él/ellos-only i→y swap), apply the matching adjustment, and otherwise just attach the plain -ar or -er/-ir endings above. Only a genuine stem change — the subject of the next chapter — takes a verb outside this system entirely.
Where to Go Next
- Chapter 27, El Pretérito Indefinido: Irregular Verbs — the verbs whose stem itself changes in the preterite (tuve, hice, dije, fui…), including the one real exception to this chapter’s “-ir stem changers are unaffected” rule.
- Chapter 28, El Pretérito Imperfecto — the other simple past tense, for ongoing, habitual, and background actions this chapter’s “bounded, finished” meaning doesn’t cover.
- Chapter 29, Preterite vs. Imperfect: Choosing the Right Past — the full decision framework for choosing between this chapter’s tense and Chapter 28’s.
- Chapter 22, Present Tense: Regular Verbs and Chapter 23, Present Tense: Stem-Changing & Irregular Verbs — the present-tense forms this chapter’s endings and stem-change contrast are both measured against.
