Preterite Tense in Spanish: How to Conjugate Past Tense Verbs
Tenses and Moods | Preterite Quiz
Grammar Guide
The preterite tense (el pretérito indefinido) is for completed past actions — events with a clear beginning or end. Unlike the imperfect, which describes ongoing or habitual past actions, the preterite tells what happened. This guide covers regular patterns, the essential irregulars, spelling changes, and the nuanced meanings that trip up even advanced learners. The quiz above drills the contrast. The guide is for review and reference.
Regular Conjugation: -AR, -ER, -IR
Regular verbs follow predictable patterns. Learn one -AR verb and one -ER/-IR verb, and you can conjugate hundreds of others.
| Pronoun | -AR (hablar) | -ER (comer) | -IR (vivir) |
|---|---|---|---|
| Yo | hablé | comí | viví |
| Tú | hablaste | comiste | viviste |
| Él / Ella / Usted | habló | comió | vivió |
| Nosotros | hablamos | comimos | vivimos |
| Vosotros | hablasteis | comisteis | vivisteis |
| Ellos / Ellas / Ustedes | hablaron | comieron | vivieron |
Note: the nosotros form of -AR verbs is identical in the present and preterite (hablamos). Context tells you which tense is meant. -ER and -IR verbs share the same preterite endings — learn one, and you’ve learned both.
High-Frequency Irregular Verbs
These verbs don’t follow the regular patterns and must be memorized. They’re the highest-frequency irregulars in the language.
| Verb | Yo | Él / Ella | Pattern |
|---|---|---|---|
| Ser / Ir | fui | fue | Identical forms — context tells you which verb |
| Hacer | hice | hizo | z in third-person singular |
| Tener | tuve | tuvo | u-stem |
| Estar | estuve | estuvo | u-stem |
| Poder | pude | pudo | u-stem |
| Querer | quise | quiso | s-stem; in affirmative preterite = “tried/wanted and did” |
| Poner | puse | puso | u-stem + s |
| Saber | supe | supo | u-stem; in preterite = “found out” |
| Dar | di | dio | Almost regular — only yo is irregular; no accent |
| Ver | vi | vio | Almost regular — only yo is irregular; no accent |
Spelling Changes
Some verbs change spelling in the preterite to preserve pronunciation or to follow a pattern. Three groups matter most.
Stem-changing -IR verbs
Only -IR verbs undergo stem changes in the preterite — and only in the third-person forms (él / ella / usted and ellos / ellas / ustedes).
| Change | Infinitive | Yo | Él / Ella | Ellos |
|---|---|---|---|---|
| E → I | Pedir (to ask) | pedí | pidió | pidieron |
| O → U | Dormir (to sleep) | dormí | durmió | durmieron |
The “Y” change (third person)
Verbs ending in -aer, -eer, -oír, -uir (e.g., caer, leer, oír, construir) add a y in the third-person forms to avoid awkward vowel combinations.
| Verb | Yo | Él / Ella | Ellos |
|---|---|---|---|
| Leer (to read) | leí | leyó | leyeron |
| Oír (to hear) | oí | oyó | oyeron |
| Construir (to build) | construí | construyó | construyeron |
The “J” stem group
Verbs like decir, traer, and conducir use a j-stem in the strong preterite. The ellos / ellas ending is -eron (not -ieron).
| Verb | Yo | Él / Ella | Ellos |
|---|---|---|---|
| Decir (to say) | dije | dijo | dijeron |
| Traer (to bring) | traje | trajo | trajeron |
| Conducir (to drive) | conduje | condujo | condujeron |
Nuanced Meanings
Some irregular verbs change meaning subtly in the preterite. These are the ones examiners love to test.
| Verb | Imperfect | Preterite |
|---|---|---|
| Querer | quería = wanted | no quiso = refused (in negative); quiso = tried/wanted and did |
| Saber | sabía = knew | supe = found out |
| Poder | podía = was able to | pude = managed to |
| Conocer | conocía = knew | conocí = met |
Common Mistakes
1. Wrong third-person form of hacer.
✗ Él hació la tarea.
✓ Él hizo la tarea.
Hacer has a z in the third-person singular: hizo, not hació.
2. Adding an “i” to the j-stem ellos form.
✗ Ellos dijieron la verdad.
✓ Ellos dijeron la verdad.
The j-stem group uses -eron (not -ieron): dijeron, trajeron, condujeron.
3. Forgetting the “y” in leer / oír / construir.
✗ Ella leió el periódico.
✓ Ella leyó el periódico.
Verbs ending in -eer, -oír, -uir change i → y in the third person: leyó, oyó, construyó.
4. Stem-changing -IR verbs changed in the wrong person.
✗ Yo pedí (with stem change to pidi-)
✓ Yo pedí (no stem change); Él pidió (stem change)
Stem changes in -IR verbs happen only in the third-person forms: pedí (no change) vs. pidió (change).
5. Using the imperfect for a completed action.
✗ Ayer comía una pizza.
✓ Ayer comí una pizza.
“Ayer” signals a completed action → preterite (comí). The imperfect (comía) would describe a habitual or ongoing past action.
6. Missing the accent on first-person singular.
✗ Yo hable con mi madre.
✓ Yo hablé con mi madre.
The yo form of -AR verbs takes an accent: hablé, not hable (which is subjunctive).

Two Sentences That Show the Difference
Ayer leí el libro.
Yesterday I read the book.
“Ayer” signals a completed action → preterite (leí). The action had a clear beginning and end.
Cuando era niño, leía mucho.
When I was a child, I read a lot.
“Cuando era niño” signals a habitual past action → imperfect (leía). The action was ongoing and repeated over time.
