The Imperfect and Telling a Story
Narration
Ask an older relative what their childhood was like, and listen to the verbs. "Vivíamos en un pueblo pequeño. Mi papá trabajaba en el campo. Los domingos íbamos al mercado." (We lived in a small town. My dad worked in the fields. On Sundays we went to the market.) None of those sentences tells about one single day. They paint what life was like, over and over, for years. Spanish has a past tense built for exactly that job: the imperfect.
You already know the preterite, the tense for what happened: *fui*, *comí*, *se fue la luz*. This unit adds the imperfect, the tense for what was going on: era, hacía frío, yo leía. Then it puts the two together. Every good story in Spanish uses both. The imperfect sets the stage, with weather, time, age, feelings and habits. The preterite moves the plot, with the doorbell, the noise, the pot that fell. A handful of verbs, like conocer, saber, querer and poder, even change meaning depending on which tense you pick.
By the end of this unit you will be able to describe a childhood memory, tell what you were doing when something interrupted you, and retell a fable or a legend such as La Llorona with the scene in the imperfect and the events in the preterite. Many heritage speakers already hear the difference between iba and fui. Here you will learn why it works, so you can use it on purpose.

The story
The Town with the Blue Doors
A grandmother in Chicago remembers her childhood town in Michoacán, one habit at a time.
Every Sunday, Daniela visits her grandmother in Little Village. This week Daniela has homework for Spanish class: interview an older relative about their childhood. She sets her phone on the kitchen table and presses record. Her grandmother, Abuela Rosa, smiles and pours two cups of hot chocolate. "¿Qué quieres saber?" (What do you want to know?) she asks.
"¿Cómo era tu pueblo?" (What was your town like?) Daniela asks. Abuela Rosa closes her eyes. "Mi pueblo era pequeño. Las casas tenían puertas azules. Había una plaza con una fuente." (My town was small. The houses had blue doors. There was a plaza with a fountain.) Daniela notices that every verb ends in -aba or -ía, or is a short word like era.
"¿Y qué hacías todos los días?" (And what did you do every day?) "Todas las mañanas, yo caminaba a la escuela con mis hermanos. Mi mamá hacía tortillas y mi papá trabajaba en el campo. Los domingos, íbamos al mercado." (Every morning, I walked to school with my brothers. My mom made tortillas and my dad worked in the fields. On Sundays, we went to the market.)
Daniela stops the recording. None of these sentences tells about one single moment. They tell what life was like, over and over, for years. "Abuela," she says, "your whole story is in the same tense." Her grandmother laughs. "Claro, mija. Así se cuentan los recuerdos." (Of course, sweetheart. That is how you tell memories.)
Talk about itAbuela Rosa never says what happened on one specific day. Why do you think her memories use a different past tense than a story about one event?
Section 1
Building the Imperfect
31.1
The -aba Endings
Main ideaRegular -ar verbs form the imperfect by dropping -ar and adding -aba, -abas, -aba, -ábamos, -abais, -aban.
Picture Abuela Rosa saying, "Yo caminaba a la escuela" (I used to walk to school). The verb is caminar (to walk). To build the imperfect, drop the -ar to get the stem camin-. Then add the ending for the subject. For yo, the ending is -aba: caminaba. The imperfect is a past tense for actions that were ongoing, repeated or in the background.
Here is the full walk-through with hablar (to speak): yo hablaba, tú hablabas, él or ella hablaba, nosotros hablábamos, vosotros hablabais, ellos hablaban. Notice two things. First, the yo form and the él/ella form are the same: hablaba. Context or a subject pronoun tells you who. Second, only the nosotros form carries a written accent: hablábamos.
English speakers often forget the accent in hablábamos, or they put one where it does not belong, as in "hablába." Say the word aloud: ha-BLÁ-ba-mos. The stress falls on the third syllable from the end, so Spanish spelling needs the accent mark. Every regular -ar verb follows this pattern, including (to work) and (to play), even though jugar changes its stem in the present. In the imperfect it is simply jugaba.
Words to know
caminar
to walk — imperfect: caminaba, caminabas, caminaba, caminábamos, caminabais, caminaban
trabajar
to work — imperfect: trabajaba (I/he/she used to work)
jugar
to play — no stem change in the imperfect: jugaba, jugábamos
el imperfecto
the imperfect — a past tense for habits, descriptions and ongoing background actions
Check yourself
1. Which is the correct nosotros imperfect form of trabajar?
Why: Nosotros adds -ábamos with a written accent. Trabajamos is present or preterite, and -íamos is for -er/-ir verbs.
2. "Mi abuelo ___ en el campo." Choose the imperfect of trabajar.
Why: Mi abuelo is él, and the él imperfect ending for -ar verbs is -aba: trabajaba.
3. What is the imperfect tú form of jugar?
Why: Jugar has no stem change in the imperfect, so it is jug- + -abas: jugabas. Jugabais is vosotros.
31.2
The -ía Endings
Main ideaRegular -er and -ir verbs share one set of imperfect endings: -ía, -ías, -ía, -íamos, -íais, -ían.
Abuela Rosa says, "Mi mamá hacía tortillas" (My mom made tortillas, again and again). The verb is hacer (to make or do). Drop the -er to get hac-, then add -ía. Even though hacer is irregular in the present and the preterite, it is regular in the imperfect. That is good news: almost every verb in Spanish is regular here.
The -er and -ir verbs share the exact same endings. Compare comer (to eat) and (to live): comía, comías, comía, comíamos, comíais, comían; vivía, vivías, vivía, vivíamos, vivíais, vivían. Every form has an accent on the í. That accent breaks the i and the a into two syllables: vi-VÍ-a, not vi-VIA.
A common mistake is mixing the two families, as in "comaba" or "vivaba." Remember the rule by the vowel: -ar verbs keep an a sound (-aba), while -er and -ir verbs switch to í (-ía). Another mistake is dropping the accent. Without it, vivia looks like a different word and is misspelled. Verbs like (to have) and (to go out) follow the pattern too: tenía, salía.
Words to know
vivir
to live — imperfect: vivía, vivías, vivía, vivíamos, vivíais, vivían
hacer
to make or do — regular in the imperfect: hacía
tener
to have — imperfect: tenía (I/he/she had, used to have)
salir
to go out or leave — imperfect: salía, salíamos
Check yourself
1. Which is the correct imperfect ella form of vivir?
Why: Vivir is an -ir verb, so it takes -ía with an accent: vivía. Vivaba mixes in the -ar ending, and vivia is missing the accent.
2. "Nosotros ___ mucho pan." Choose the imperfect of comer.
Why: -er verbs take -íamos for nosotros, with an accent: comíamos.
3. Why is hacer easy in the imperfect?
Why: Hacer is irregular in other tenses but regular in the imperfect: hac- + -ía.
31.3
Only Three Irregulars
Main ideaOnly ser, ir and ver are irregular in the imperfect: era, iba and veía.
When Abuela Rosa says, "Mi pueblo era pequeño" (My town was small), she uses ser (to be). Ser does not follow the -ía pattern. Its imperfect forms are era, eras, era, éramos, erais, eran. Notice that only éramos has an accent, just like hablábamos. The stress falls on the third syllable from the end.
The second irregular is (to go): iba, ibas, iba, íbamos, ibais, iban. It looks like an -ar verb even though ir is an -ir verb. "Los domingos, íbamos al mercado" means "On Sundays, we used to go to the market." The third irregular is (to see): veía, veías, veía, veíamos, veíais, veían. Ver just keeps its e before the regular -ía ending.
That is the whole list. Spanish has dozens of irregular verbs in the preterite, but only three in the imperfect. Students sometimes invent forms like "seía" or "iría." Seía does not exist, and iría is the conditional (I would go), a different tense. When you see era, iba or veía, you know you are in the imperfect.
Words to know
ser
to be — imperfect: era, eras, era, éramos, erais, eran
ir
to go — imperfect: iba, ibas, iba, íbamos, ibais, iban
ver
to see or watch — imperfect: veía, veías, veía, veíamos, veíais, veían
Check yourself
1. Which is the imperfect nosotros form of ir?
Why: Ir is irregular: íbamos, with an accent. Fuimos is preterite and iríamos is conditional.
2. "Cuando ___ niños, vivíamos en Pátzcuaro." Which form fits?
Why: Ser in the imperfect for nosotros is éramos. Seíamos does not exist.
3. What does "Mis primos veían la tele" mean?
Why: Veían is the imperfect of ver for ellos, so it describes a repeated past habit: used to watch.
31.4
Había: There Was, There Were
Main ideaThe imperfect of hay is había, which means both there was and there were.
Abuela Rosa describes her plaza: " una fuente y había muchos árboles" (There was a fountain and there were many trees). In the present you say hay (there is, there are). In the imperfect, hay becomes había. It comes from the verb haber, and it is one of the most useful words for describing a scene.
English changes the verb for singular and plural: there was, there were. Spanish does not. Había stays the same no matter what follows: había un perro (there was a dog), había tres perros (there were three dogs). A very common error is "habían muchos árboles." Many native speakers say it, but standard Spanish uses the singular había.
Había is perfect for describing a (town square) or (the market) in a memory. "En el mercado había frutas, flores y música." (At the market there were fruits, flowers and music.) Once you have había, you can build a whole picture of a place, one detail at a time.
Words to know
había
there was, there were — the imperfect of hay; it never changes for plural
la plaza
the town square — the center of many Mexican and Latin American towns
el mercado
the market — often open-air, with food, flowers and crafts
la fuente
the fountain (also means source)
Check yourself
1. "En mi escuela ___ muchos estudiantes." Which form is standard Spanish?
Why: Había stays singular even before a plural noun in standard Spanish.
2. What does "Había un gato en la ventana" mean?
Why: Había is the imperfect of hay: there was.
3. What is the present-tense form that había comes from?
Why: Hay means there is or there are; its imperfect is había.
Section 2
Habits and Descriptions
31.5
Used To and Would
Main ideaThe imperfect tells what someone used to do or would do again and again in the past.
Think about something you did every summer when you were small. Maybe you went to the pool or visited a cousin. In English you might say "I used to swim" or "I would swim every day." In Spanish, one form covers both: nadaba. "Todos los veranos, nadaba en el lago." (Every summer, I used to swim in the lake.)
Words of repetition often travel with the imperfect. (always), todos los días (every day), cada domingo (every Sunday), (often) and (from time to time) all signal a habit. "Mi papá siempre se levantaba a las cinco." (My dad always got up at five.) The habit happened many times, so Spanish uses the imperfect.
Be careful with English would. "I would go to the market" can mean a past habit (imperfect: iba) or something that depends on a condition (conditional: iría). Ask yourself: is this describing what used to happen? If yes, use the imperfect. English speakers who translate would word for word often write iría when they need iba.
Words to know
siempre
always — a common clue for a repeated past habit
a menudo
often — Íbamos al río a menudo. (We often went to the river.)
de vez en cuando
from time to time, once in a while
todos los días
every day — signals a routine
Check yourself
1. "When I was little, I would eat cereal every morning." Which verb fits?
Why: This would describes a past habit, so Spanish uses the imperfect comía, not the conditional comería.
2. Which phrase signals a repeated habit?
Why: De vez en cuando (from time to time) describes something that happened repeatedly.
3. What does "Siempre visitábamos a mis tíos" mean?
Why: Siempre plus the imperfect visitábamos describes a regular past habit.
31.6
Describing People and Places
Main ideaUse the imperfect to describe how people, places and things were in the past.
Imagine a photo of Abuela Rosa’s house. It does not move, but it has details. "La casa era de adobe. Tenía un patio con macetas. La cocina olía a canela." (The house was made of adobe. It had a patio with flowerpots. The kitchen smelled of cinnamon.) Each verb describes how things were, so each is imperfect.
Physical and personality descriptions also go in the imperfect. "Mi abuelo era alto y . Llevaba un sombrero de paja." (My grandfather was tall and quiet. He wore a straw hat.) Use ser for traits: era alto. Use estar for conditions and locations: la casa estaba cerca del río (the house was near the river).
Students sometimes use the preterite for descriptions because it feels like "the" past tense: "La casa fue grande." That sentence sounds odd, as if the house was big for a set time and then stopped. For a description of how something was, choose the imperfect: la casa era grande. Words like and help you build the setting.
Words to know
callado
quiet (person) — callada for a woman or girl
el patio
the courtyard or patio, often in the center of a house
el adobe
adobe — sun-dried brick of earth and straw used in many older homes
llevar
to wear or carry — Llevaba un sombrero. (He wore a hat.)
Check yourself
1. "Mi escuela ___ grande y moderna." Which verb best describes it in the past?
Why: Describing what the school was like uses ser in the imperfect: era.
2. "La casa ___ cerca del río." Which verb fits?
Why: Location uses estar, and a past description uses the imperfect: estaba.
3. What does "Mi abuelo llevaba un sombrero de paja" mean?
Why: Llevaba is the imperfect of llevar (to wear), describing him.
31.7
Age, Time and Weather
Main ideaAge, clock time and weather in the past are background facts, so they use the imperfect.
"Cuando siete años, aprendí a nadar." (When I was seven, I learned to swim.) In Spanish you have years, so age uses tener. Age in the past is a background fact, so it uses the imperfect: tenía. Saying "era siete años" is a common mistake from English; Spanish always uses tener for age.
Clock time in the past also uses the imperfect of ser. "Era la una" (It was one o’clock) uses the singular because una is one hour. For every other hour, use the plural: "Eran las ocho" (It was eight o’clock). The time does not start or end in the story; it is simply the setting.
Weather works the same way. " frío" (It was cold), "hacía sol" (it was sunny), "" (it was raining) and "" (it was snowing) all describe the conditions. Put age, time and weather together and you have an opening line: "Eran las siete, hacía frío y yo tenía doce años." (It was seven, it was cold and I was twelve.)
Words to know
tenía
had; with años, was (age) — Tenía diez años. (I/he/she was ten.)
hacía
it was (weather) — hacía calor, hacía frío, hacía viento
llovía
it was raining — imperfect of llover
nevaba
it was snowing — imperfect of nevar
Check yourself
1. How do you say "I was ten years old"?
Why: Spanish uses tener for age, and background age in the past is imperfect: tenía.
2. "___ las tres cuando llegamos." Which form fits?
Why: Time in the past uses the imperfect of ser, plural for every hour except one: eran las tres.
3. What does "Hacía mucho viento" mean?
Why: Hacía with weather words describes past weather: it was windy.
Section 3
Memories of Childhood
31.8
Cuando Era Niño o Niña
Main ideaCuando era niño or cuando era niña (when I was a child) opens a memory and sets up the imperfect.
Many memories in Spanish begin with the same four words: "..." or "Cuando era niño..." (When I was a child...). The ending matches the speaker: a girl or woman says niña, a boy or man says niño. Daniela’s grandmother says, "Cuando era niña, vivía en Michoacán." (When I was a girl, I lived in Michoacán.)
The phrase sets a long stretch of time as the background. Everything that fits inside that stretch usually follows in the imperfect too. "Cuando era niño, mi familia tenía una tienda y yo ayudaba después de clases." (When I was a boy, my family had a store and I helped after school.) You can swap in other stages: cuando era joven (when I was young), cuando estaba en primaria (when I was in elementary school).
Michoacán is a state in western Mexico, and many families in Chicago have roots there. Memories are often shared at the table in more than one language. If your relatives mix Spanish and English, that is normal. The pattern still holds: cuando era niño or niña, then imperfect verbs that paint (childhood).
Words to know
cuando era niña
when I was a girl (a boy says cuando era niño)
la niñez
childhood — En mi niñez... (In my childhood...)
joven
young — cuando era joven (when I was young)
el recuerdo
the memory — Tengo un recuerdo bonito. (I have a nice memory.)
Check yourself
1. A boy wants to say "When I was a child, I lived in Aurora." Which is correct?
Why: A boy says niño; the background of childhood uses era and vivía.
2. What does "Cuando era joven, mi abuela bailaba mucho" mean?
Why: Era joven sets the time, and bailaba describes a repeated habit.
3. Why does cuando era niña use ser and not estar?
Why: Stages of life like niño, joven and viejo describe what someone was, so they take ser.
31.9
Soler: Usually Did
Main ideaSoler in the imperfect plus an infinitive means used to or usually did something.
Spanish has a special verb for habits: (to usually do). It is always followed by an infinitive, the basic -ar, -er or -ir form of another verb. "Solía leer antes de dormir" means "I used to read before sleeping." Soler does the job of the habit, and leer names the action.
In the past, soler is almost always in the imperfect: solía, solías, solía, solíamos, solíais, solían. It is a regular -er verb here. "Mis padres solían cenar tarde." (My parents used to have dinner late.) Compare it with the plain imperfect: "Mis padres cenaban tarde." Both are correct and mean nearly the same thing. Solía simply puts a spotlight on the habit.
Two mistakes are common. First, conjugating both verbs: "solía leía." Only soler changes; the second verb stays an infinitive (the unconjugated form). Second, using soler for one event. "Ayer solía correr" does not make sense, because ayer (yesterday) is one day and soler means a habit.
Words to know
soler
to usually do — solía + infinitive: used to, usually did
el infinitivo
the infinitive — a verb's basic form ending in -ar, -er or -ir (leer, jugar)
cenar
to have dinner — Solíamos cenar juntos. (We used to have dinner together.)
Check yourself
1. Which sentence uses soler correctly?
Why: Only soler is conjugated (solíamos); the second verb stays an infinitive: jugar.
2. What does "Mi abuela solía cantar en la cocina" mean?
Why: Solía + infinitive describes a past habit: used to sing.
3. Why is "Ayer solía correr" wrong?
Why: Soler means usually do, so it cannot describe a single day like ayer.
31.10
Feelings and States in the Past
Main ideaHow someone felt or what they thought or wanted in the past is usually background, so it goes in the imperfect.
Daniela asks, "¿Estabas contenta en tu pueblo?" (Were you happy in your town?) Her grandmother answers, "Sí, pero a veces extrañaba a mi papá cuando viajaba." (Yes, but sometimes I missed my dad when he traveled.) Feelings that lasted over time, like being happy or missing someone, are states, not events. Spanish puts them in the imperfect.
Verbs of thinking and wanting work the same way. "Pensaba que la ciudad era enorme" (I thought the city was huge). "Quería ser maestra" (I wanted to be a teacher). "No sabía leer" (I didn’t know how to read). Estar with emotions is very common: estaba nerviosa, estaba cansado, estábamos (we were excited).
Watch for the English word "was." It can become era, estaba, fue or estuvo, depending on the meaning. For a feeling or condition in the background, estaba is usually right: "Estaba triste" (I was sad). Choosing fue for a feeling is a common error. Save the preterite for a feeling that began at a clear moment, which you will study in the next chapter.
Words to know
extrañar
to miss (someone or something) — Extrañaba mi pueblo. (I missed my town.)
emocionado
excited — emocionada for a girl or woman; emocionados for a group
querer
to want or love — imperfect: quería (I/he/she wanted)
pensar
to think — imperfect: pensaba (I/he/she thought)

1. "I was tired" as a background feeling. Which is best?
Why: A temporary feeling uses estar, and as background it takes the imperfect: estaba cansado.
2. What does "No sabía nadar" mean?
Why: Sabía is the imperfect of saber; with an infinitive it means knew how to.
3. Which sentence describes a lasting wish in the past?
Why: Quería, the imperfect, describes a wish that lasted over time.

Preterite and Imperfect Together
Aspect
Big questionHow do you choose between two past tenses to tell a story that makes sense?
The story
The Night the Lights Went Out
A storm, a power outage and two versions of what really happened.
On Monday, Marco and his sister Lucía both tell their Spanish class about the storm on Saturday night. Marco goes first. "Era tarde. Llovía mucho y hacía viento. Yo leía en mi cuarto y Lucía veía una película." (It was late. It was raining hard and it was windy. I was reading in my room and Lucía was watching a movie.)
"De repente, se fue la luz." (Suddenly, the power went out.) The class leans in. "Oí un ruido muy fuerte en la cocina. Tomé mi linterna y bajé la escalera." (I heard a very loud noise in the kitchen. I grabbed my flashlight and went down the stairs.) Marco's voice drops. "Había una sombra enorme en la pared." (There was a huge shadow on the wall.)
Lucía raises her hand. "Eso no es exactamente lo que pasó." (That's not exactly what happened.) She tells her version. "Yo tenía hambre, entonces fui a la cocina. Estaba muy oscuro. Abrí el refrigerador y se cayó una olla." (I was hungry, so I went to the kitchen. It was very dark. I opened the refrigerator and a pot fell.) The shadow was Lucía, holding a banana.
The teacher, Señora Ortiz, writes two columns on the board. On the left: era, llovía, leía, veía, había, tenía, estaba. On the right: se fue, oí, tomé, bajé, fui, abrí, se cayó. "Look," she says. "The left column is the stage. The right column is the plot. You need both to tell a good story."
Talk about itLook at Señora Ortiz's two columns. What kinds of information end up on the left, and what kinds end up on the right?
Section 1
Scene and Action
32.1
The Stage and the Plot
Main ideaThe imperfect sets the scene in the background, and the preterite moves the story forward with completed actions.
Think of a movie. Before anything happens, the camera shows the setting: rain, a dark house, a boy reading. That is the : era tarde, llovía, Marco leía. Then something happens: the lights go out, a noise, footsteps. Those events are the preterite: se fue la luz, oí un ruido, bajé. The imperfect is the stage; the preterite is the plot.
The preterite shows actions as complete, with a beginning or an end in view. Each one moves the story to its next step. "Tomé la linterna, bajé la escalera y abrí la puerta." (I grabbed the flashlight, went down the stairs and opened the door.) If you can put "and then" between the verbs, they are probably preterite.
The imperfect shows actions in progress or states with no clear beginning or end. "Hacía frío y todos dormían." (It was cold and everyone was sleeping.) Nothing moves forward; the camera just looks around. The difference between these two views of an action is called (aspect). English marks it less clearly, which is why this choice takes practice.
Words to know
el pretérito
the preterite — past tense for completed events that move a story forward
el imperfecto
the imperfect — past tense for background, habits and actions in progress
el aspecto
aspect — whether an action is viewed as complete or ongoing
la linterna
the flashlight
Check yourself
1. In "Llovía cuando salí," what does llovía do?
Why: Llovía is imperfect: it describes the ongoing weather in the background.
2. Which sentence lists plot events in order?
Why: A sequence of completed actions (and then...) takes the preterite.
3. Which verb describes the scene, not an event?
Why: Había (there was) is imperfect and describes the setting.
32.2
Interrupted Actions
Main ideaAn action in progress takes the imperfect, and the action that interrupts it takes the preterite.
"Leía cuando sonó el teléfono." (I was reading when the phone rang.) Two things happen in this sentence. Reading was already going on; it is the background, so it is imperfect. The phone ringing cut in at one moment; it is the event, so it is preterite. The word (when) often links the two.
You can flip the order and keep the same tenses. "Cuando sonó el teléfono, yo leía." Or use an interruption with another subject: "Lucía comía cuando se fue la luz." (Lucía was eating when the power went out.) A good test: which action was already in progress? That one is imperfect. Which one happened suddenly? That one is preterite.
English speakers sometimes put both verbs in the preterite: "Leí cuando sonó el teléfono." That means "I read when the phone rang," as if you started reading because of the call. English "was -ing" is a strong hint for the imperfect. Words like (suddenly) usually point to the preterite event that interrupts.
Words to know
cuando
when — often links a background action and an interrupting event
de repente
suddenly — usually introduces a preterite event
sonar
to ring or sound — preterite: sonó (it rang)
leer
to read — imperfect: leía (was reading); preterite: leyó
Check yourself
1. "Yo ___ la cena cuando ___ mi hermano."
Why: Cooking was in progress (preparaba); the brother's arrival interrupted it (llegó).
2. What does "Dormíamos cuando empezó la tormenta" mean?
Why: Dormíamos is the action in progress; empezó is the event that happened.
3. Why is "Leí cuando sonó el teléfono" odd for "I was reading when the phone rang"?
Why: An action in progress needs the imperfect, leía.
32.3
Two Things at Once
Main ideaTwo actions going on at the same time in the past both take the imperfect, often joined by mientras.
" yo leía, Lucía veía una película." (While I was reading, Lucía was watching a movie.) Neither action interrupts the other. Both were in progress at the same time, like two cameras showing two rooms. When two background actions run side by side, both take the imperfect. Mientras means while.
Compare these two sentences. "Mientras mamá cocinaba, papá lavaba los platos." (While Mom was cooking, Dad was washing the dishes.) Both actions are ongoing. "Mientras mamá cocinaba, sonó el teléfono." (While Mom was cooking, the phone rang.) Now the second action is an interruption, so it switches to the preterite.
Mientras usually pairs with the imperfect for the action in progress. A common error is writing "mientras cociné," which sounds like a single finished act. You can also use estar in the imperfect with a gerund, the -ando or -iendo form: "Estaba leyendo" (I was reading). It stresses that the action was in the middle of happening, just like (at that moment).
Words to know
mientras
while — joins two actions happening at the same time
estaba leyendo
I/he/she was reading — imperfect of estar + gerund, stresses an action in progress
en ese momento
at that moment
lavar los platos
to wash the dishes
Check yourself
1. "Mientras yo ___, mi hermano ___ la tarea."
Why: Two simultaneous ongoing actions both take the imperfect.
2. Which sentence shows an interruption?
Why: Se cayó is a sudden preterite event that interrupts the ongoing singing.

Clues for the Preterite
Main ideaWords that point to one moment or a closed period, like ayer or de repente, usually signal the preterite.
Some time words point to a specific moment or a finished block of time. (yesterday), anoche (last night), el sábado (on Saturday), la semana pasada (last week), (once) and de repente (suddenly) all pin an action to a clear time. "Anoche se fue la luz." (Last night the power went out.)
Phrases with a clear length or count also call for the preterite. "Viví en Morelia tres años" (I lived in Morelia for three years) treats the three years as a closed block. "Llamé dos veces" (I called twice) counts the events. " terminé" (I finally finished) marks an ending.
Clue words are helpful, but they are not magic. They show what is usually true. The real question is always how the speaker sees the action: as a complete event or as ongoing background. Still, if you see ayer, anoche or de repente, check your verb. Nine times out of ten, the preterite is the right choice.
Words to know
ayer
yesterday — often signals the preterite
una vez
once, one time — counts a single event
por fin
finally, at last — marks a completed action
anoche
last night

1. "Ayer ___ al cine con mis primos."
Why: Ayer marks one completed outing, so the preterite fui fits.
2. Which phrase most likely signals the preterite?
Why: De repente marks a sudden single event.
3. "Viví en Texas cinco años" treats the five years as...
Why: A stated length of time presented as finished takes the preterite.
32.5
Clues for the Imperfect
Main ideaWords for habits, ongoing time and background, like siempre, mientras and de niño, usually signal the imperfect.
The imperfect has its own clue words. Words of habit, like siempre, todos los días, cada verano (every summer), (usually) and a menudo (often), point to repeated actions. "Cada verano visitábamos a mis abuelos." (Every summer we used to visit my grandparents.)
Words that stretch time also point to the imperfect: mientras (while), (as a child), en aquella época (back then) and todavía (still). "En aquella época no había internet en el pueblo." (Back then there was no internet in the town.) These phrases open a window onto a long stretch of time rather than one moment.
Some words can go either way. Cuando can introduce background (cuando era niño) or an event (cuando sonó el teléfono). Siempre can even take the preterite for a finished period: "Siempre fue mi mejor amigo" (He was always my best friend, and that time is over). Use clues as hints, then ask: scene or plot?
Words to know
generalmente
usually, generally — signals a habit
de niño
as a child (de niña for a girl) — sets a long background period
en aquella época
back then, in those days
todavía
still, yet — Todavía llovía. (It was still raining.)
Check yourself
1. "De niña, yo ___ con muñecas."
Why: De niña sets a long background period of habits: jugaba.
2. Which clue word points to a past habit?
Why: Generalmente (usually) describes something that happened regularly.
3. What does "Todavía llovía cuando salimos" mean?
Why: Todavía llovía is ongoing background; salimos is the event.
32.6
Same Verb, Two Stories
Main ideaSwitching one verb between preterite and imperfect changes what the sentence tells the listener.
Look at two sentences. "Iba a la biblioteca" means "I was going to the library" or "I used to go to the library." "Fui a la biblioteca" means "I went to the library," one completed trip. Same verb, same subject, different story. The tense tells the listener how to picture the action.
Here is another pair. "Mi abuela cocinaba" says she used to cook, or she was cooking when something else happened. "Mi abuela cocinó" says she cooked, and the meal was done. Adding a clue helps: "Mi abuela cocinaba cuando llegamos" (She was cooking when we arrived) versus "Mi abuela cocinó y luego comimos" (She cooked and then we ate).
In Lucía’s story, both tenses matter. "Fui a la cocina" (I went to the kitchen) is a trip she finished. "Iba a la cocina cuando oí el ruido" (I was going to the kitchen when I heard the noise) freezes her in the hallway. Good storytellers use this (contrast) on purpose to control the (pace) of a story.
Words to know
el contraste
the contrast — a difference shown side by side
el ritmo
the rhythm or pace of a story
luego
then, later — often links preterite events in order
la biblioteca
the library

1. Which sentence means the apple is finished?
Why: The preterite comió presents the eating as complete.
2. What does "Iba a la tienda cuando te vi" mean?
Why: Iba is the action in progress; vi is the event that interrupted it.
3. Why would a writer choose "Hablábamos" instead of "Hablamos"?
Why: The imperfect shows the action as ongoing or habitual.
Section 3
Verbs That Shift Meaning
32.7
Conocer and Saber
Main ideaIn the preterite, conocer means met for the first time and saber means found out.
Some verbs change meaning when you switch tenses. (to know a person or place) is one. "Conocía a Lucía" (I knew Lucía) describes an ongoing acquaintance. "Conocí a Lucía en 2019" (I met Lucía in 2019) marks the moment the knowing began. In the preterite, conocer usually means met.
(to know a fact) shifts too. "Sabía la verdad" (I knew the truth) is a background state. "Supe la verdad" (I found out the truth) marks the moment the knowledge arrived. The preterite of saber is irregular: supe, supiste, supo, supimos, supisteis, supieron, with no written accents.
English uses different verbs here, so learners often translate "met" with encontré. Encontrar means to find, or to run into by chance. For meeting someone for the first time, Spanish uses conocí. And for "I found out," use supe or me enteré, not "sabí," which does not exist.
Words to know
conocer
to know (a person or place) — preterite conocí often means I met
saber
to know (a fact) — preterite supe means I found out
enterarse
to find out — Me enteré de la noticia. (I found out about the news.)
Check yourself
1. How do you say "I met my best friend in third grade"?
Why: The preterite conocí marks the first meeting.
2. What does "Supimos la noticia anoche" mean?
Why: Supimos, the preterite of saber, means found out.
3. Which is the correct yo preterite of saber?
Why: Saber has an irregular preterite stem sup- and no accent: supe.
32.8
Querer and Poder
Main ideaIn the preterite, quise means I tried, no quise means I refused, pude means I managed, and no pude means I failed.
Querer (to want) in the imperfect describes a wish: "Quería salir" (I wanted to go out). In the preterite, it becomes an action. "Quise abrir la puerta" suggests I tried to open the door. In the negative, the shift is stronger: "No quise comer" means I refused to eat. Preterite forms: quise, quisiste, quiso, quisimos, quisisteis, quisieron.
Poder (to be able to) follows a similar path. "Podía correr rápido" (I could run fast) describes a general ability. "Pude terminar" means I managed to finish, and it happened. "No pude dormir" means I tried and failed to sleep. Preterite forms: pude, pudiste, pudo, pudimos, pudisteis, pudieron.
In the storm story, Marco says, "Quise encender la luz, pero no pude." (I tried to turn on the light, but I couldn’t.) Lucía adds, "No quise decir nada." (I refused to say anything.) If Marco had said "no podía," it would sound like a general or ongoing inability. The preterite pins it to one failed attempt.
Words to know
quise
I tried (preterite of querer); no quise means I refused
pude
I managed to (preterite of poder); no pude means I failed, I couldn't
encender
to turn on (a light) or light (a candle)
la vela
the candle

3. Which sentence describes a general ability in the past?
Why: The imperfect podía describes an ongoing ability.
Section 4
Telling a Tale
32.9
Retelling a Fable
Main ideaA retold fable opens with imperfect background, moves with preterite events and ends with a lesson.
A (fable) is a short story, often with animals, that teaches a lesson. Many fables in Spanish begin with "Había una vez..." (Once upon a time there was...). Había sets the scene. Then more imperfect verbs describe the characters: "Había una vez una liebre que era muy rápida y muy orgullosa." (Once upon a time there was a hare who was very fast and very proud.)
Then something happens, and the preterite takes over. "Un día, la liebre vio a una tortuga y se rió de ella. La tortuga la desafió a una carrera." (One day, the hare saw a tortoise and laughed at her. The tortoise challenged her to a race.) Un día (one day) is a classic signal that the plot is starting.
In the middle, the two tenses mix. "Mientras la tortuga caminaba despacio, la liebre dormía bajo un árbol. Cuando se despertó, la tortuga ya cruzaba la meta." (While the tortoise walked slowly, the hare was sleeping under a tree. When she woke up, the tortoise was already crossing the finish line.) The story ends with (the moral): "Poco a poco se llega lejos." (Little by little you go far.)
Words to know
la fábula
the fable — a short tale that teaches a lesson
había una vez
once upon a time there was — the classic opening of a tale
la moraleja
the moral — the lesson at the end of a fable
la liebre
the hare — the fast, proud runner in the fable; la tortuga is the tortoise
Check yourself
1. Why does "Había una vez una liebre" use the imperfect?
Why: The opening of a tale describes the setting, which is background.
2. "Un día, la tortuga ___ a la liebre a una carrera."
Why: Un día signals a single completed event: the preterite desafió.
3. In "Cuando se despertó, la tortuga ya cruzaba la meta," which verb is the background?
Why: Cruzaba is imperfect: the tortoise was already crossing when the hare woke up.
32.10
La Llorona in Outline
Main ideaA legend like La Llorona uses the imperfect for its eerie setting and the preterite for the events that made the legend.
(the legend) of La Llorona (the Weeping Woman) is told across Mexico, the U.S. Southwest and other parts of Latin America. Versions differ from town to town and family to family. In outline, a woman loses her children near a river, and afterward her spirit wanders at night, crying for them. Many families tell it to warn children to stay away from the water after dark.
Tellers often start with the setting in the imperfect. "Hace muchos años, en un pueblo junto a un río, vivía una mujer." (Many years ago, in a town beside a river, there lived a woman.) The key events move to the preterite: "Un día, perdió a sus hijos en el río." (One day, she lost her children in the river.)
Then the story returns to the imperfect to describe what happens again and again. "Desde entonces, todas las noches se oía un junto al agua." (Since then, every night a cry could be heard by the water.) Because the legend has so many versions, ask your family how they tell it. Notice which verbs set the mood and which ones tell what happened.
Words to know
la leyenda
the legend — a traditional story passed down, often with many versions
el llanto
the weeping, crying — La Llorona means the weeping woman
desde entonces
since then, from then on
el río
the river — where the legend of La Llorona takes place: junto al río (beside the river)

Use de repente or un día to switch to the preterite for the events.
Check every accent: hablábamos, comía, llegó, supe (no accent).
Try one mientras sentence and one cuando sentence with an interruption.
Read it aloud and ask: is this verb the scene or the plot?
