Two cameras, one story
Think of past narration as a film shoot with two cameras. The imperfect is the wide shot: scenery, weather, what people were doing, how things used to be. The preterite is the action camera: it catches each event as it happens and moves the plot forward.
Our Study Desk lesson gives you the core completed-vs-ongoing test. This unit trains the skill that test feeds into: narrating, sentence after sentence, choosing the right camera every time.
Forming the imperfect
The imperfect is the friendliest tense in Spanish: two ending sets and only three irregular verbs in the entire language.
- The only irregulars: ser (era, eras, era, éramos, erais, eran), ir (iba, ibas...), ver (veía, veías...).
| Person | hablar | comer / vivir |
|---|---|---|
| yo | hablaba | comía / vivía |
| tú | hablabas | comías / vivías |
| él / ella / usted | hablaba | comía / vivía |
| nosotros | hablábamos | comíamos / vivíamos |
| vosotros | hablabais | comíais / vivíais |
| ellos / ustedes | hablaban | comían / vivían |
What the imperfect paints
- Background and description: Era de noche y llovía. (It was nighttime and it was raining.)
- Habits and repeated actions: De niño jugaba al fútbol. (As a child I used to play soccer.)
- Age, time, and states: Tenía ocho años. Eran las diez. (I was eight. It was ten o'clock.)
- Actions in progress at a past moment: Caminaba a casa. (I was walking home.)
| Cuando era joven, vivíamos en Sevilla. | When I was young, we lived in Seville. both verbs paint background, so both imperfect |
| Todos los veranos íbamos a la playa. | Every summer we used to go to the beach. a repeated habit takes the imperfect |
What the preterite reports
Each completed event in the storyline takes the preterite: she opened the door, the phone rang, we left. String preterites together and the story advances step by step.
| Llegué a casa, cené y me acosté. | I got home, had dinner, and went to bed. three plot events in sequence, all preterite |
The classic combo: interruption
The most common mixed sentence: an ongoing scene in the imperfect, interrupted by an event in the preterite, usually joined by cuando.
| Caminaba a casa cuando vi a Marta. | I was walking home when I saw Marta. caminaba sets the scene; vi is the event |
| Mientras cocinaba, sonó el teléfono. | While I was cooking, the phone rang. mientras + imperfect, then the preterite interruption |
| Dormíamos cuando empezó la tormenta. | We were sleeping when the storm began. |
After mientras (while), expect the imperfect. After de repente (suddenly), expect the preterite. These markers are near-mechanical signals.
Verbs that shift meaning
A few verbs translate differently depending on the tense, because the preterite turns a state into an event.
| Verb | Imperfect | Preterite |
|---|---|---|
| saber | sabía = I knew | supe = I found out |
| conocer | conocía = I knew (a person, place) | conocí = I met |
| querer | quería = I wanted | quise = I tried; no quise = I refused |
| poder | podía = I was able (in general) | pude = I managed to |
| Sabía la respuesta, pero supe la verdad ayer. | I knew the answer, but I found out the truth yesterday. |
| Conocí a mi esposa en 2010; ya conocía a su hermano. | I met my wife in 2010; I already knew her brother. |
A model narration
Read this micro-story and watch the cameras switch. Background in the imperfect, plot in the preterite.
| Era sábado y llovía. Yo leía en el sofá. De repente, alguien llamó a la puerta. Abrí y vi a mi vecino, que estaba empapado. | It was Saturday and it was raining. I was reading on the sofa. Suddenly, someone knocked at the door. I opened it and saw my neighbor, who was soaked. era, llovía, leía, estaba paint the scene; llamó, abrí, vi drive the plot |
Pronunciation corner
The imperfect endings carry a soft b sound (written b) or a stressed í. Both deserve a few slow repetitions.
| hablaba | [aˈβlaβa] | ah-BLAH-ba; both b sounds are soft, lips barely touching |
| llovía | [ʝoˈβia] | yo-BEE-ah; the í gets its own clear beat |
| veía | [beˈia] | beh-EE-ah; three vowels, keep them separate |
| éramos | [ˈeɾamos] | EH-rah-mos; stress the first syllable |

Frequently asked questions
Can one sentence mix the preterite and the imperfect?
Yes, constantly. The most common pattern is an ongoing scene in the imperfect interrupted by a preterite event: leía cuando sonó el teléfono, I was reading when the phone rang. Real narration switches between the tenses sentence by sentence and often clause by clause.
Does 'used to' always translate as the imperfect?
For past habits, yes: íbamos al parque, we used to go to the park. Watch the other English 'would': in 'I would go if I could', would signals the conditional (iría), a different tense. If you can replace 'would' with 'used to', the imperfect is right.
Which tense do I use for age, time, and weather in the past?
Default to the imperfect, because these are background states: tenía diez años, eran las cinco, hacía frío. Use the preterite only to frame them as bounded events, such as ayer hizo frío, meaning yesterday as a completed whole was cold.
Is the imperfect hard to conjugate?
It is the easiest tense in the language. Regular -ar verbs take -aba endings, -er and -ir verbs take -ía endings, and only ser, ir, and ver are irregular. The difficulty lives entirely in choosing between imperfect and preterite, and that is a trainable skill.
