Unit 15 · The Preterite: What Happened

Picture a friend asking what you did yesterday. You answer with actions that are done: you ate lunch, you studied, you called your grandmother. Spanish has a special tense for these finished actions, the pretérito (the preterite). A tense is a set of verb forms that shows time. The preterite answers the question "What happened?" with actions that have a clear start and end.

Compare two sentences. "Hablo con mi abuela" means I talk with my grandmother, now or usually. "Hablé con mi abuela anoche" means I talked with my grandmother last night, and the call is over. The stem habl- stays the same. Only the ending changes: -o for now, -é for a finished past. That single ending carries the whole idea of time.

The preterite is used for single events (Llegué a las ocho, I arrived at eight), for actions in a series (Entré, saludé y me senté, I came in, said hello and sat down), and for actions with a set length (Estudié dos horas, I studied for two hours). English speakers sometimes use "did" in questions, like "Did you study?" Spanish does not need an extra word: "¿Estudiaste?" already means Did you study?

When Marcos asked about Saturday, the word el sábado told Daniela to answer in the past. Spanish speakers use many time words like this. ayer means yesterday. anoche means last night. Anteayer means the day before yesterday. These words set the moment, and the preterite verb tells what happened at that moment.

Another group uses pasado or pasada, meaning last or past. The ending matches the noun: la semana pasada (last week) uses pasada because semana is feminine, while el año pasado (last year) and el mes pasado (last month) use pasado because año and mes are masculine. A common mistake is la semana pasado, which breaks gender agreement.

You can also count back with hace. "Hace dos días" means two days ago. "Visité a mi tía hace una semana" means I visited my aunt a week ago. Notice the word order: English puts ago at the end, but Spanish puts hace first, then the amount of time. Time words can start or end the sentence: "Ayer bailé" and "Bailé ayer" both mean I danced yesterday.

Imagine you hear only one word from a conversation across the cafeteria: "Trabajó." Did someone work, or does someone work? The ending -ó with its accent tells you it is past: he or she worked. "Trabajo" without an accent would mean I work. Listening for endings is the key skill of this chapter.

Here is a side-by-side walk-through with trabajar (to work). Present: trabajo, trabajas, trabaja. Preterite: trabajé, trabajaste, trabajó. The stem trabaj- never changes. You drop -ar and add a new ending. Every preterite ending for yo and for él or ella in regular verbs carries a written accent, and that accent is stressed when you say it.

Time words help too. "Siempre trabajo los sábados" (I always work on Saturdays) is a habit, so it takes the present. "El sábado pasado trabajé seis horas" (Last Saturday I worked six hours) is one finished event, so it takes the preterite. When you write, look for a time word first, then choose the ending that matches it.

Daniela said "Canté todas las canciones" (I sang all the songs). Let’s build the whole preterite of cantar (to sing). Drop -ar to get the stem cant-. Then add: yo canté, tú cantaste, él or ella or usted cantó, nosotros cantamos, vosotros cantasteis, ellos or ellas or ustedes cantaron.

Every regular -ar verb works the same way. Bailar (to dance): bailé, bailaste, bailó, bailamos, bailasteis, bailaron. comprar (to buy): compré, compraste, compró, compramos, comprasteis, compraron. If you know the six endings, you know hundreds of verbs, because most -ar verbs in Spanish are regular.

A frequent mistake is adding an extra -s to the tú form: "cantastes" instead of cantaste. You may hear cantastes in casual speech in some places, but standard written Spanish uses cantaste. Another mistake is mixing present and past: "Ellos cantan anoche" should be "Ellos cantaron anoche." The -aron ending marks ellos in the past.

Look at two words that seem almost the same: hablo and habló. In hablo, the stress falls on HA. In habló, the stress moves to the last syllable, LÓ, and the written acento (accent mark) shows that move. The first means I speak. The second means he, she or you (usted) spoke. One mark changes both the person and the time.

The same thing happens with the yo form. Hable, with no accent, is a command form (let him speak, or speak! to usted). Hablé, with the accent, means I spoke. So the accent on -é and -ó is not decoration. Leaving it off turns a past-tense sentence into a different sentence. Teachers mark this as a meaning error, not just a spelling error.

Practice by saying pairs aloud and stressing the final syllable in the preterite: compro and compró, estudio and estudió, llego and llegó. Heritage speakers often say these correctly without thinking but forget the accent when writing. A good habit is to check every yo and él form in the preterite before you turn in your work.

Here is a surprise. "Hablamos" can mean we speak or we spoke. For -ar verbs, the nosotros form ends in -amos in both the present and the preterite. The form is identical, so Spanish speakers rely on context: the time words and the rest of the conversation.

"Hablamos todos los días" means we talk every day, a habit in the present. "Hablamos ayer" means we talked yesterday, a finished past action. The word ayer does all the work. The same is true for caminar (to walk): caminamos can mean we walk or we walked. Look for clues like ayer, anoche, el lunes pasado or hace una hora.

This is also true for -ir verbs: vivimos means we live or we lived. But -er verbs are different. In the present, we eat is comemos; in the preterite, we ate is comimos. So comimos can only be past. Daniela’s line "Comimos tacos" had to be about Saturday night, even without a time word.

After the concert, Daniela and her cousin ate tacos al pastor. Let’s build comer (to eat) in the preterite. Drop -er to get com-. Add: yo comí, tú comiste, él or ella comió, nosotros comimos, vosotros comisteis, ellos comieron. Notice the i in every ending.

Now try vivir (to live). Drop -ir to get viv-. Add the very same endings: viví, viviste, vivió, vivimos, vivisteis, vivieron. In the preterite, -er and -ir verbs are twins. That is good news: you learn one set of endings and use it for both groups.

Watch the accents again. Comí and comió both carry a written accent, just like canté and cantó. A common mistake is using -ar endings on an -er verb, like "comé" or "comó." Those are not Spanish words. Another is writing "comieron" as "comeron"; the ellos ending is -ieron, with the i before the e.

Marcos said "Yo no salí" (I didn’t go out). salir (to go out, to leave) is irregular in the present yo form (salgo), but in the preterite it is completely regular: salí, saliste, salió, salimos, salisteis, salieron. Don’t let a present-tense irregular scare you; check the preterite on its own.

volver (to return) is a stem-changing verb in the present: vuelvo, vuelves. In the preterite, -er stem changes disappear. You say volví, volviste, volvió, volvimos, volvisteis, volvieron, with the o from the infinitive. A common error is "vuelví," which mixes the present stem with a past ending.

Put them together and you can tell a night out: "Salimos a las siete. Aprendimos un baile nuevo. Volvimos a casa a las once." (We went out at seven. We learned a new dance. We came back home at eleven.) aprender (to learn) follows the pattern too: aprendí, aprendiste, aprendió. Three verbs, one set of endings, one clear story.

Conversations about the past bounce between tú and yo. Marcos asked "¿Cantaste?" and Daniela answered "Canté." The question uses -aste, and the answer switches to -é. With -er and -ir verbs, "¿Comiste?" (Did you eat?) becomes "Sí, comí" (Yes, I ate). This switch is the most common move in real conversations.

A classic mistake is answering with the same form you heard: "¿Escribiste la tarea?" "Sí, escribiste." That answer means Yes, you wrote. You need escribí. When a teacher uses usted, the ending is -ó or -ió: "¿Terminó usted?" means Did you finish? and still takes a yo answer: "Sí, terminé."

To say no, put no before the verb: "No, no comí" (No, I didn’t eat). The first no answers the question; the second makes the verb negative. English needs didn’t, but Spanish just uses no plus the preterite. Question words work the same way: "¿Dónde comiste?" (Where did you eat?) "Comí en Pilsen" (I ate in Pilsen).

Say buscar (to look for) and listen to the hard k sound in bus-CAR. When you add the yo ending -é, the letters c + é would sound like s in most of the Spanish-speaking world, and the word would sound wrong. To keep the k sound, Spanish writes qu instead: busqué (I looked for).

This change happens only in the yo form. The other forms keep the c because the ending starts with a or o: buscaste, buscó, buscamos, buscasteis, buscaron. The same rule applies to tocar (to play an instrument): toqué, tocaste, tocó. And to sacar (to take out, to get a grade): saqué una A (I got an A).

This is not an irregular verb. The sound follows the regular pattern; only the spelling adjusts. Students often write "buscé" or "tocé." Say those aloud with Latin American pronunciation and you hear bus-SÉ, not bus-KÉ. The spelling change keeps the word’s sound the same across all six forms.

Daniela said "Llegamos temprano," but if she were alone she would say "Llegué temprano" (I arrived early). llegar has a hard g sound. Before e, the letter g alone sounds like the Spanish j (a breathy h sound), so Spanish adds a silent u: llegué. The other forms stay plain: llegaste, llegó, llegaron. Jugar (to play a sport or game) works the same: jugué, jugaste, jugó. Pagar gives pagué.

Verbs ending in -zar change z to c before e. empezar (to begin) gives empecé (I began), but empezó (it began). almorzar (to eat lunch) gives almorcé. Here the sound does not change; Spanish spelling simply prefers ce over ze in most words, like cero and cena. Cruzar (to cross) gives crucé.

Put the three groups together with one memory line: car → qué, gar → gué, zar → cé, and only in yo. Other forms never change. A heritage speaker who says these words perfectly may still write "llegé" or "empezé" on a test. When you write the yo preterite of any verb ending in -car, -gar or -zar, stop and check the spelling.

Jazmín said "Fuimos al museo" (We went to the museum) and then "Fue un día increíble" (It was an incredible day). The word fuimos comes from ir (to go). The word fue comes from ser (to be). In the preterite, these two very different verbs use exactly the same six forms.

Here is the full set: yo fui, tú fuiste, él or ella or usted fue, nosotros fuimos, vosotros fuisteis, ellos or ustedes fueron. Notice that fui and fue have no written accent. They are one-syllable words, so they need no accent. Writing "fuí" or "fué" is a common mistake; the accent was dropped from these words in the official spelling rules long ago.

The ending pattern is also odd. The ellos form is fueron, not "fuieron." Students sometimes try to make fue look regular by writing "fuió," which is not a word. The easiest approach is to memorize the six forms as a chant: fui, fuiste, fue, fuimos, fuisteis, fueron. You will use them in almost every story about the past.

Because ser and ir share forms, you read them by their neighbors. Ir almost always has a place or a direction. The little word a (to) is a strong clue: "Fue a la biblioteca" means she went to the library. Question words help too: "¿Adónde fuiste?" (Where did you go?) must be ir.

Ser usually comes with a description, a job, or an event. "Fue fácil" means it was easy. "Fue mi maestra" means she was my teacher. "¿Cómo fue el concierto?" means How was the concert? There is no destination, so it is ser. Think: is someone going somewhere, or is something being described?

Here is a tricky one: "Fui al concierto y fue genial." The first fui is ir (I went to the concert) because of al. The second fue is ser (it was great) because genial is a description. English speakers sometimes translate every fue as went. Slow down and check the words after the verb.

Jazmín said "Vimos el esqueleto de Sue" (We saw Sue’s skeleton). ver (to see) uses the regular -er endings: vi, viste, vio, vimos, visteis, vieron. The only surprise is that vi and vio have no accent. Like fui and fue, they are one syllable, so they need none.

dar (to give) is an -ar verb, but in the preterite it borrows the -er/-ir endings: di, diste, dio, dimos, disteis, dieron. A student guessing from the -ar pattern would write "dé" or "dó," which are wrong here. Think of dar as a verb dressed in ver’s clothes: di and vi, dio and vio.

Dar is common in useful phrases. "Le di un regalo a mi mamá" means I gave my mom a gift. "El guía nos dio un mapa" means the guide gave us a map. Ver shows up whenever you describe a trip: "¿Qué viste?" (What did you see?) "Vi dinosaurios, momias y piedras preciosas" (I saw dinosaurs, mummies and gemstones).

The question "¿Qué hiciste?" (What did you do?) opens almost every conversation about the past. It uses hacer (to do, to make), one of the most important irregular verbs. Its preterite stem is hic-, not hac-. The forms are hice, hiciste, hizo, hicimos, hicisteis, hicieron.

Look closely at two things. First, hice and hizo end in -e and -o with no accent. Irregular-stem preterites do not stress the last syllable, so they need no accent mark. Second, hizo is spelled with z, not c. If you wrote "hico," the c before o would sound like k. Spanish uses z to keep the s sound (in Latin America) before o.

Hacer answers and asks. "¿Qué hizo tu hermano?" (What did your brother do?) "Hizo la tarea y luego hizo la cena" (He did his homework and then made dinner). Note that the answer to a hacer question often uses another verb: "¿Qué hiciste el sábado?" "Fui a la playa." You don’t need to repeat hacer in the answer.

Kevin said "Tuve que esperar" (I had to wait) and "Estuve allí media hora" (I was there half an hour). These verbs belong to a family with a u in the preterite stem. tener becomes tuv-, estar becomes estuv-, poder becomes pud-, and poner becomes pus-.

All of them take the same special endings: -e, -iste, -o, -imos, -isteis, -ieron. So tener gives tuve, tuviste, tuvo, tuvimos, tuvisteis, tuvieron. Poder gives pude, pudiste, pudo, pudimos, pudisteis, pudieron. The yo and él forms end in plain -e and -o with no accent. Writing "tuvé" or "pudó" is the most common error here.

Some of these verbs shift meaning in the preterite. "No pude ver todo" means I couldn’t see everything, in the sense that I tried and failed. "Tuve que esperar" means I had to wait, and I did. Estar in the preterite tells how long someone was somewhere: "Estuvimos en el museo cinco horas" (We were at the museum for five hours).

Some irregular verbs change their stem vowel to i. venir (to come) becomes vin-: vine, viniste, vino, vinimos, vinisteis, vinieron. querer (to want) becomes quis-: quise, quisiste, quiso, quisimos, quisisteis, quisieron. They use the same accent-free endings as the u-stem group.

Be careful with vino. It is also the noun meaning wine, but in a sentence like "Mi prima vino al museo" it means my cousin came to the museum. Context makes it clear. Another trap is mixing up the present and past: vengo (I come) versus vine (I came). The g appears only in the present yo form.

Querer changes meaning in the preterite. "Quise llamarte" means I tried to call you. "No quiso comer" means he refused to eat, not just that he didn’t feel like it. So Kevin could say "No quise esperar, pero tuve que esperar" (I didn’t want to wait, but I had to wait). The preterite makes wanting sound like a decision.

Jazmín reported that "mi amiga dijo que Sue es enorme" (my friend said that Sue is huge). decir (to say, to tell) uses the stem dij-: dije, dijiste, dijo, dijimos, dijisteis, dijeron. traer (to bring) uses traj-: traje, trajiste, trajo, trajimos, trajisteis, trajeron.

Look at the ellos form. After j, the ending is -eron, not -ieron. So it is dijeron, not "dijieron." This mistake is very common, even among fluent speakers, but standard Spanish writes dijeron and trajeron. The rule: when the stem ends in j, drop the i.

Decir is the verb of reporting. "Me dijo la verdad" means he told me the truth. "¿Qué dijiste?" means What did you say? Traer shows up on trips and at parties: "Traje mi almuerzo" (I brought my lunch). "¿Quién trajo la cámara?" (Who brought the camera?) Both verbs use no accent in yo and él forms.

Ana said "Leí todos los carteles" (I read all the signs). Try building leer (to read) with the regular endings. The stem is le-. Yo: leí. Tú: leíste. But for él, le- + ió would give three vowels in a row, "leió." Spanish changes that unstressed i to y: leyó. The ellos form becomes leyeron.

creer (to believe) and oír (to hear) follow the same rule: creyó, creyeron; oyó, oyeron. The other forms add written accents to keep the i as its own syllable: leí, leíste, leímos, leísteis; creí, creíste, creímos. Without the accent, leíste would be read as one blended sound.

These are not irregular verbs in meaning or stem. They follow the regular endings, and spelling simply keeps them pronounceable. A good tip: whenever the stem ends in a vowel and the ending is -ió or -ieron, expect a y. "Mi abuela leyó el periódico" (My grandmother read the newspaper). "¿Oyeron la música?" (Did you all hear the music?)

Ana joked that "en el autobús, Kevin durmió" (on the bus, Kevin slept). dormir (to sleep) has a stem change in the present (duermo). In the preterite, -ar and -er verbs lose their stem changes, but -ir verbs keep a smaller change in two forms. The o becomes u only in él and ellos: dormí, dormiste, durmió, dormimos, dormisteis, durmieron.

pedir (to ask for, to order) does the same with e→i: pedí, pediste, pidió, pedimos, pedisteis, pidieron. Servir (to serve) gives sirvió and sirvieron. Preferir (to prefer) gives prefirió. Morir (to die) gives murió. Think of it as a change that appears only in the third person, both singular and plural.

Two mistakes are common. One is using the present stem in every form: "duermí" or "piediste." The other is forgetting the change in the third person: "Kevin dormió." Remember: yo, tú, nosotros and vosotros keep the infinitive stem, and only él and ellos change. "Pedí un sándwich y mi amiga pidió una sopa" (I ordered a sandwich and my friend ordered a soup).

Now you can tell the whole museum trip. Start with the setting: "El viernes fuimos al Field Museum." Add actions in order with words like primero (first), luego (then) and después (afterward): "Primero vimos a Sue. Luego estuvimos en la sala de Egipto. Después comimos en la cafetería."

As you write, sort each verb into its family. Regular -ar: visitamos, caminamos. Regular -er/-ir: comimos, salimos. Ser/ir: fuimos, fue. New stems: hicimos, tuvimos, pudimos, vinieron, dijo. Spelling changes: llegué, leyó. Third-person stem change: durmió, pidió. Knowing the family tells you the ending and whether it needs an accent.

End with a reaction, which often uses ser: "Fue un día fantástico" (It was a fantastic day). Before you share, reread for the three biggest errors: missing accents on regular yo and él forms (llegó, comí), extra accents on irregular ones (hizo, tuvo, fue), and -ieron after j (dijeron, not dijieron). Those checks fix most mistakes.
