Spanish past tense conjugation trips up more students than any other part of the language, and the reason is simple: Spanish has two everyday past tenses where English has one. The preterite and the imperfect both translate to “I spoke” or “I was speaking,” and choosing between them is a judgment call about how the action happened, not a rule you can look up.
This guide covers the full endings for both tenses, the irregular verbs worth memorizing, the two compound past tenses you will meet later, and a decision test for picking the right one in real sentences.
Quick Answer
Spanish has two simple past tenses. The preterite describes completed actions with a clear start or end, formed with endings like hablé and comí. The imperfect describes ongoing or habitual past actions, formed with endings like hablaba and comía. Choosing between them depends on whether the action had a boundary.
Key Takeaways
- Spanish has two simple past tenses: the preterite for completed actions and the imperfect for ongoing or habitual ones.
- Regular preterite endings split into two sets: one for -ar verbs and one shared by -er and -ir verbs.
- The imperfect has only three irregular verbs in the entire language: ser, ir, and ver.
- About a dozen preterite irregulars cover most of what you will actually say, including tener, hacer, estar, and decir.
- Six common verbs change meaning depending on which past tense you use, including saber, conocer, and querer.

The Two Past Tenses in Spanish
Spanish uses the preterite (pretérito indefinido) for actions with a clear start and finish, and the imperfect (pretérito imperfecto) for actions that were ongoing, repeated, or setting the scene. English collapses both into the simple past, which is why the distinction feels invisible to English speakers at first.
Compare these two sentences:
- Comí a las ocho. I ate at eight. One meal, finished, done.
- Comía a las ocho. I used to eat at eight. A routine, repeated over some stretch of time.
Same verb, same subject, completely different meaning. The tense carries information that English has to add with extra words like “used to” or “would.”
Preterite Conjugation: The Full Endings
The preterite has two sets of regular endings. One for verbs ending in -ar, and one shared by verbs ending in -er and -ir. Drop the infinitive ending, add the new one.
| Subject | -ar (hablar) | -er (comer) | -ir (vivir) |
|---|---|---|---|
| yo | hablé | comí | viví |
| tu | hablaste | comiste | viviste |
| el / ella / usted | habló | comió | vivió |
| nosotros | hablamos | comimos | vivimos |
| vosotros | hablasteis | comisteis | vivisteis |
| ellos / ellas / ustedes | hablaron | comieron | vivieron |
Written accents matter here. Hablo with no accent is “I speak,” present tense. Habló with an accent on the final o is “he spoke.” Same five letters, two different tenses, and the accent is the only thing separating them.
Notice that the nosotros form of -ar and -ir verbs is identical in the present and the preterite. Hablamos means both “we speak” and “we spoke.” Context does the work, and native speakers rely on it constantly.
Imperfect Conjugation: The Easier Half
The imperfect is the most regular tense in Spanish. Two sets of endings, three irregular verbs in the entire language, and no stem changes to worry about.
| Subject | -ar (hablar) | -er / -ir (comer, vivir) |
|---|---|---|
| yo | hablaba | comía / vivía |
| tu | hablabas | comías / vivías |
| el / ella / usted | hablaba | comía / vivía |
| nosotros | hablábamos | comíamos / vivíamos |
| vosotros | hablabais | comíais / vivíais |
| ellos / ellas / ustedes | hablaban | comían / vivían |
The yo and el forms are identical in the imperfect, so speakers often keep the subject pronoun to avoid ambiguity. Yo hablaba and el hablaba are the same word with a different pronoun in front.
The only three irregular verbs in the imperfect
| Subject | ser (to be) | ir (to go) | ver (to see) |
|---|---|---|---|
| yo | era | iba | veía |
| tu | eras | ibas | veías |
| el / ella / usted | era | iba | veía |
| nosotros | éramos | íbamos | veíamos |
| vosotros | erais | ibais | veíais |
| ellos / ellas / ustedes | eran | iban | veían |
That is the complete list. Memorize these three and you have mastered every irregular imperfect form in Spanish.
Irregular Preterite Verbs Worth Memorizing
The preterite is where the irregulars pile up. The good part is that most of them follow a shared pattern: an irregular stem plus a single set of endings that has no written accents at all.
Those shared endings are -e, -iste, -o, -imos, -isteis, -ieron.
| Infinitive | Irregular stem | yo form | el form | ellos form |
|---|---|---|---|---|
| tener (to have) | tuv- | tuve | tuvo | tuvieron |
| estar (to be) | estuv- | estuve | estuvo | estuvieron |
| poder (to be able) | pud- | pude | pudo | pudieron |
| poner (to put) | pus- | puse | puso | pusieron |
| saber (to know) | sup- | supe | supo | supieron |
| hacer (to do, make) | hic- | hice | hizo | hicieron |
| querer (to want) | quis- | quise | quiso | quisieron |
| venir (to come) | vin- | vine | vino | vinieron |
| decir (to say) | dij- | dije | dijo | dijeron |
Two things to watch. Hacer changes c to z in the el form (hizo) to keep the sound consistent. And decir drops the i in the ellos ending: dijeron, not dijieron. Verbs with a j stem always do this.
Ser and ir share the same preterite
Ser (to be) and ir (to go) have identical preterite forms: fui, fuiste, fue, fuimos, fuisteis, fueron. Context tells you which verb you are hearing.
- Fui profesor. I was a teacher. That is ser.
- Fui a Madrid. I went to Madrid. That is ir.
Dar (to give) is also worth flagging because it takes -er endings despite being an -ar verb: di, diste, dio, dimos, disteis, dieron.
How to Choose Between Preterite and Imperfect
Here is the test that works in most sentences. Ask whether the action has a boundary. If you can point to the moment it started or finished, use the preterite. If it is background, habit, or description with no clear edge, use the imperfect.
| Use the preterite for | Use the imperfect for |
|---|---|
| A completed action: Terminé la tarea. | A habit: Siempre terminaba la tarea tarde. |
| A specific number of times: Fui tres veces. | An ongoing state: Estaba cansado. |
| An action that interrupts: Sonó el teléfono. | The scene being interrupted: Yo dormía. |
| A defined stretch of time: Viví allí dos años. | Age, time, and weather: Tenía diez años. Llovía. |
| A sequence of events in a story | Physical and emotional description in a story |
Trigger words that point you to the right tense
Certain time expressions almost always pull one tense or the other. They are not laws, but they are reliable enough to lean on while you build instinct.
- Preterite signals: ayer, anoche, la semana pasada, el año pasado, de repente, una vez, entonces.
- Imperfect signals: siempre, todos los días, mientras, generalmente, a menudo, cada verano, de niño.
The six verbs that change meaning
A handful of verbs mean genuinely different things depending on the tense. This is the detail that separates intermediate students from beginners, and it shows up constantly in real conversation.
| Verb | Imperfect | Preterite |
|---|---|---|
| saber | Sabía. I knew (a fact). | Supe. I found out. |
| conocer | Conocía. I knew (a person, place). | Conocí. I met. |
| poder | Podía. I was able to. | Pude. I managed to. |
| no poder | No podía. I was not able to. | No pude. I tried and failed. |
| querer | Quería. I wanted to. | Quise. I tried to. |
| no querer | No quería. I did not want to. | No quise. I refused. |
The Two Compound Past Tenses
Beyond the preterite and imperfect, Spanish has two compound past tenses built with the helper verb haber plus a past participle. Both map cleanly onto English, so they are easier than they look.
Present perfect (pretérito perfecto)
Formed with the present tense of haber plus a participle. Used for actions that happened recently or that still connect to now.
| Subject | haber | Example |
|---|---|---|
| yo | he | He comido. I have eaten. |
| tu | has | Has llegado. You have arrived. |
| el / ella / usted | ha | Ha salido. He has left. |
| nosotros | hemos | Hemos vivido aqui. We have lived here. |
| vosotros | habéis | Habéis visto. You all have seen. |
| ellos / ellas / ustedes | han | Han terminado. They have finished. |
Participles are regular for most verbs: -ar becomes -ado (hablado), -er and -ir become -ido (comido, vivido). The common irregulars are hecho (hacer), dicho (decir), visto (ver), escrito (escribir), puesto (poner), and vuelto (volver).
Usage varies by region. In Spain, the present perfect is used constantly for anything that happened today. In most of Latin America, speakers reach for the preterite instead: Comí hoy rather than He comido hoy. Both are correct in their own place.
Past perfect (pluscuamperfecto)
Formed with the imperfect of haber (había, habías, había, habíamos, habíais, habían) plus a participle. It describes something that happened before another past event.
Cuando llegué, ya habían cenado. When I arrived, they had already eaten. The eating happened first, the arriving second, and the past perfect makes the order explicit.
Practice Exercises
Fill in the correct past tense. Answers follow each set.
- De niño, yo (jugar) en el parque todos los sábados. Answer: jugaba. Repeated habit, so imperfect.
- Ayer nosotros (ver) una película. Answer: vimos. One completed event, so preterite.
- Mientras ella (leer), su hermano (entrar). Answer: leía, entró. Background action plus interruption.
- Yo no (saber) que estabas aquí hasta ayer. Answer: supe. Found out at a specific moment.
- El ano pasado ellos (vivir) en Bogotá. Answer: vivieron. Defined stretch of time with an endpoint.
- Siempre (hacer) frío en esa casa. Answer: hacía. Ongoing description of weather.
If you got four or more right, you have the core distinction. The remaining work is volume, not theory.
One more thing worth knowing if you are planning ahead. The preterite and imperfect split exists across the whole Romance family, so a Spanish speaker picking up Portuguese, Italian or French finds the same two tenses waiting, with different endings on the same logic. The grammar you build here transfers.

Frequently Asked Questions About Spanish Past Tense Conjugation
How many past tenses does Spanish have?
Spanish has two simple past tenses, the preterite and the imperfect, plus two compound ones, the present perfect and the past perfect. Most everyday speech uses the preterite and imperfect. Students typically learn those two first and add the compound tenses at the intermediate level.
What is the difference between preterite and imperfect?
The preterite describes completed actions with a clear beginning or end. The imperfect describes ongoing actions, habits, and background conditions. Comí means I ate, once, finished. Comía means I used to eat, repeatedly, over an unspecified period.
Which Spanish past tense should I learn first?
Start with the imperfect. It has only two sets of endings and three irregular verbs in the whole language, so you can conjugate almost anything within a week. The preterite has far more irregulars and takes longer to internalize.
Why do some Spanish past tense verbs have accent marks?
Written accents mark which syllable is stressed, and in the preterite they also prevent confusion with other tenses. Hablo without an accent means I speak. Habló with an accent on the final o means he spoke. Dropping the accent changes both the tense and the subject.
How long does it take to master Spanish past tenses?
Most students can conjugate both tenses accurately within two to three months of consistent study. Choosing correctly between them in live conversation usually takes six months to a year, because the decision has to become automatic rather than calculated.
Do all Spanish-speaking countries use the past tenses the same way?
The conjugations are identical everywhere. Usage differs in one notable way: Spain uses the present perfect for recent events where most of Latin America uses the preterite. The vosotros forms are also standard in Spain and largely absent elsewhere.
