What is the imperfect tense?
The imperfect is a past tense used to describe ongoing, habitual, or background actions in the past. In Spanish, the imperfect is not a single-purpose form: it covers repeated past actions, how things used to be, time and weather descriptions, mental states, and physical or emotional conditions that set the scene for other events.
Why the imperfect matters
English often uses used to or would for repeated past actions, and simple past continuous or descriptive phrases for background details. Spanish uses the imperfecto to express all those ideas with specific conjugations that make the meaning clear in one verb form.
Forming the imperfect
Imperfect conjugations are regular for most verbs, with a few irregulars. Here are the endings for the two verb groups and the irregular verb.
For -ar verbs: -aba, -abas, -aba, -ábamos, -abais, -aban
Example: hablar — yo hablaba, tú hablabas, él/ella hablaba, nosotros hablábamos, vosotros hablabais, ellos/ellas hablaban
For -er and -ir verbs: -ía, -ías, -ía, -íamos, -íais, -ían
Examples: comer — yo comía, tú comías, él/ella comía, nosotros comíamos, vosotros comíais, ellos/ellas comían
vivir — yo vivía, tú vivías, él/ella vivía, nosotros vivíamos, vosotros vivíais, ellos/ellas vivían
Irregular: ir — iba, ibas, iba, íbamos, ibais, iban
Irregular: ser — era, eras, era, éramos, erais, eran
Irregular: ver — veía, veías, veía, veíamos, veíais, veían
When to use the imperfect for habits
Use the imperfect to describe actions that used to happen repeatedly or habitually in the past. In English, these are often translated as used to or would when talking about past routines.
Key signals that call for the imperfect
Look for words that indicate repetition or habitual action: siempre, normalmente, todos los días, cada verano, de niño, cuando era pequeño, a menudo. These signal the imperfect, though context always matters.
Examples: habitual actions
Cuando era niño, jugaba en el parque todos los días.
Translation: When I was a child, I used to play in the park every day.
Mis abuelos cocinaban juntos los domingos.
Translation: My grandparents used to cook together on Sundays.
Antes iba al gimnasio por la mañana, pero ahora voy por la tarde.
Translation: Before I used to go to the gym in the morning, but now I go in the evening.
Using the imperfect to talk about age in the past
To state someone’s age at a past time, Spanish uses the imperfect of tener. English often uses was or were + age, but Spanish requires tenía + number to express age in the past.
Structure and examples
Structure: tener (imperfect) + number + años
Cuando tenía diez años, vivíamos en Madrid.
Translation: When I was ten years old, we lived in Madrid.
En esa época, ella tenía veinticinco años y trabajaba en una librería.
Translation: At that time, she was twenty-five years old and worked in a bookstore.
Note that Spanish does not use the verb ser for age in this context. Always use a form of tener when giving age, and use the imperfect when the statement refers to the past.
Descriptions and background information
The imperfect is the go-to tense for descriptions in the past. This includes physical descriptions, personality traits, time, weather, and settings that provide the backdrop for other events.
Physical and personality descriptions
Use the imperfect to describe appearances or habitual characteristics. These descriptions set the scene rather than pinpoint a completed action.
La casa era grande y tenía ventanas azules.
Translation: The house was big and had blue windows.
Mi profesor era muy paciente y siempre explicaba todo con calma.
Translation: My teacher was very patient and always explained everything calmly.
Time, weather, and ongoing states
Time and weather in the past are often described with the imperfect because they form the context for actions.
Ernesto estudiaba cuando sonó el teléfono. In this sentence, estudiaba is imperfect to show the ongoing action, while sonó is preterite to indicate the completed interruption.
Era la una de la tarde y hacía sol.
Translation: It was one in the afternoon and it was sunny.
Imperfect vs. preterite: how to choose
Choosing between the imperfect and the preterite is one of the most important skills in Spanish narrative. Use the imperfect for ongoing, habitual, or descriptive past actions. Use the preterite for actions that are completed, specific, or interrupt an ongoing activity.
Common patterns
Background description + specific event: imperfect sets the scene; preterite tells what happened.
Example combination:
Mientras yo leía el libro, mi hermano llegó a casa.
Translation: While I was reading the book, my brother arrived home.
In this example, leía is imperfect because it describes the ongoing activity; llegó is preterite because it marks a single completed event that interrupts the reading.
Contrastive examples
Imperfect for habit: Cuando vivíamos en Perú, comíamos ceviche todos los fines de semana.
Preterite for a single completed action: Una vez comimos ceviche en la playa y nos enfermamos.
Translation: When we lived in Peru, we used to eat ceviche every weekend. Once we ate ceviche on the beach and we got sick.
Common verbs and expressions often used with the imperfect
Certain verbs frequently appear in imperfect contexts because they describe states or ongoing activities: ser, estar, tener, gustar, querer, creer, saber, conocer (in the sense of knowing), and pensar (for ongoing thoughts). Verbs that describe habitual actions such as jugar, trabajar, estudiar also commonly use the imperfect when referring to past habits.
Examples:
Ella querría is conditional; but for past ongoing desire: Ella quería aprender piano. (She wanted to learn piano.)
Yo conocía a mucha gente en esa ciudad. (I knew many people in that city.)
Usage notes and cultural tips
Contractions and casual speech: In spoken Spanish, especially in Latin America, the imperfect is used naturally and sometimes combined with time expressions to emphasize routine. Be careful: some English translations may seem less literal but are correct in context.
Regional variation: The imperfect functions the same across Spanish-speaking regions, but narrative styles can differ. For instance, speakers in some areas may prefer the imperfect to soften statements or add background detail where others might use periphrastic constructions.
Politeness and storytelling: Using the imperfect to describe habits or character traits can make statements sound less abrupt and more narrative-like. This is useful in storytelling and polite descriptions of past situations.
Putting it all together: narrative examples
Short narrative using imperfect for habits, age, and descriptions followed by a preterite to show action:
Cuando era niña, vivíamos en una casa cerca del río. Tenía un jardín grande y muchos árboles. Mis hermanos y yo jugábamos todo el día; por la tarde mi madre preparaba la cena y cantaba mientras cocinaba. Un verano, mientras jugábamos en el jardín, encontramos una caja vieja debajo de un árbol y decidimos abrirla.
Translation: When I was a child, we lived in a house near the river. It had a big garden and many trees. My siblings and I used to play all day; in the afternoon my mother would prepare dinner and sing while she cooked. One summer, while we were playing in the garden, we found an old box under a tree and decided to open it.
Quick reference: when to use the imperfect
– For habitual or repeated actions in the past: yo caminaba, nosotros comíamos.
– To state age or describe physical characteristics in the past: ella tenía veinte años, era alta.
– For background descriptions: weather, time, ongoing mental or emotional states: hacía frío, era la una, estaba cansado.
– To describe what someone used to do: antes jugábamos al fútbol todos los sábados.
Conclusion
Mastering the Spanish imperfect opens up your ability to tell stories, describe people and places, and speak naturally about past routines and ages. Remember the conjugation patterns for -ar and -er/-ir verbs, use tener in the imperfect to say past ages, and contrast the imperfect with the preterite to distinguish background from completed actions. With practice, the imperfect becomes an intuitive part of your Spanish narrative toolbox.
