Spanish Imperfect: ER/IR Verbs (comía, vivía)
ía suffix to describe the ongoing background and habits of your past life.
Grammar Rule in 30 Seconds
The Imperfect tense describes ongoing past actions or habits using the suffix -ía for all ER and IR verbs.
- Remove the -er or -ir ending from the infinitive.
- Add the imperfect endings: -ía, -ías, -ía, -íamos, -íais, -ían.
- Remember that all forms carry a written accent on the 'i'.
Overview
The Spanish Imperfect tense, particularly for verbs ending in -er and -ir, serves as a fundamental linguistic tool for recounting the past from a perspective of ongoingness, habituality, or description. It contrasts sharply with the Preterite, which focuses on completed actions. The Imperfect allows you to paint vivid pictures of past scenarios, describing what things were like, what actions were in progress, or what routines used to occur, rather than isolating specific, concluded events.
This tense is indispensable for storytelling, setting background scenes, and detailing the conditions that prevailed in a past moment.
Mastering the Imperfect for -er and -ir verbs is streamlined by their shared conjugation pattern. This consistency highlights a phonological preference within Spanish verb morphology, where both verb categories receive identical endings, distinct from -ar verbs. The presence of a consistent accent mark on the í in all forms (-ía) is not merely a orthographic detail; it ensures correct stress placement, maintaining the natural rhythm and pronunciation of the verb across conjugations.
This shared pattern simplifies memorization and application, providing a robust foundation for narrating past events with nuance.

How This Grammar Works
Ayer leí un libro (Yesterday I read a book) is a snapshot of a finished event.Cuando era niño, leía muchos libros (When I was a child, I used to read many books) depicts an ongoing habit over an extended period. The action of leía (reading) is presented as a continuous or iterative activity, not as a discrete, finished occurrence.was/were -ing or used to; these are simply common English approximations that capture some of its functions. The Imperfect intrinsically signals duration, iteration (repetition), or description within a past context. For instance, Vivía en un pueblo pequeño can convey I was living in a small town (duration), I used to live in a small town (habitual), or simply I lived in a small town when the emphasis is on the conditions or duration rather than the act of moving there or leaving.-er and -ir verbs in the Imperfect is a feature of their historical development within Latin, where they often shared conjugational paradigms. The consistent í accent across all forms is critical for maintaining prosody—the natural stress and rhythm of the language. Without this accent, the stress would shift, altering pronunciation and potentially creating ambiguity or misinterpretation.comia (without the accent) would naturally be stressed on the penultimate syllable (co-MI-a), which is phonetically incorrect for the Imperfect, which requires stress on the í (co-MÍ-a). This accent ensures that the stress always falls on the characteristic Imperfect vowel.Formation Pattern
-er and -ir verbs is one of the most predictable conjugational patterns in Spanish. Its regularity is a significant advantage for learners, as there are only three truly irregular verbs in the entire Imperfect tense across all verb categories (ser, ir, ver). For all other regular -er and -ir verbs, the process is consistent:
-er or -ir (e.g., aprender, correr, escribir, asistir).
-er or -ir to reveal the verb stem. This stem is the base to which you will attach the Imperfect endings. For aprender, the stem is aprend-. For escribir, the stem is escrib-.
í is included in all forms. The endings are: -ía, -ías, -ía, -íamos, -íais, -ían.
Correr (to run)
corr-
Yo corría (I used to run / was running)
Tú corrías (You used to run / were running)
Él/Ella/Ud. corría (He/She/You used to run / was/were running)
Nosotros/as corríamos (We used to run / were running)
Vosotros/as corríais (You all used to run / were running - Spain)
Ellos/Ellas/Uds. corrían (They/You all used to run / were running - LatAm/Spain)
Asistir (to attend)
asist-
Yo asistía (I used to attend / was attending)
Ella asistía a la universidad (She was attending university).
Nosotros asistíamos a clases de baile (We used to attend dance classes).
-er and -ir verbs provides a robust framework for describing myriad past situations, from habitual childhood activities to ongoing historical events.
When To Use It
-er and -ir verbs is employed when the narrative focus is on the duration, repetition, or descriptive nature of past actions or states, rather than their completion. It provides context and background. Understanding its distinct applications is key to fluent communication:- To Describe Past Conditions, People, or Places (Setting the Scene): Use the Imperfect to depict what things were like in the past. This often sets the stage for other events.
La ciudad tenía calles estrechas y edificios antiguos.(The city had narrow streets and old buildings.)Ella era una persona muy alegre y siempre llevaba ropa colorida.(She was a very cheerful person and always wore colorful clothes.)
- To Express Habitual or Repeated Actions in the Past (
used to/would): When discussing routines, customs, or actions that occurred regularly over a period of time in the past, without a specific endpoint. In English, this often translates toused toorwould(for past habit). Cuando vivía en la costa, comía pescado fresco todos los días.(When I lived on the coast, I used to eat fresh fish every day.)Cada verano, mis primos y yo corríamos por el bosque.(Every summer, my cousins and I would run through the forest.)
- To Describe Actions Ongoing in the Past (
was/were -ing): Use the Imperfect for actions that were in progress when another event happened, often a single event in the Preterite that interrupts or coincides. The Imperfect provides the background action. Nosotros escribíamos un informe cuando se fue la luz.(We were writing a report when the power went out.)Mientras tú aprendías a conducir, yo trabajaba en la tienda.(While you were learning to drive, I was working at the store.)
- To Express Age in the Past: In Spanish, age is expressed with
tener(to have), and when speaking about age in the past, the Imperfect is always used. Mi hermano tenía doce años cuando nos mudamos.(My brother was twelve years old when we moved.)
- To Tell Time or Describe Weather in the Past: When stating what time it was or describing weather conditions, the Imperfect is the correct tense.
Eran las tres de la tarde y hacía mucho sol.(It was three in the afternoon and it was very sunny.)
- To Describe Mental, Emotional, or Physical States: For feelings, thoughts, desires, or physical conditions that endured for a period in the past, rather than a sudden onset or termination.
Yo quería estudiar medicina desde pequeño.(I wanted to study medicine since I was little.)Ellos sentían mucha alegría al recordar su viaje.(They felt a lot of joy remembering their trip.)
- To Report Indirect Speech or Thoughts in the Past: When reporting what someone thought, said, or believed in the past, where the original statement was concurrent with the past perspective.
Ella dijo que creía en tus ideas.(She said that she believed in your ideas.)
Common Mistakes
-er/-ir verbs. Recognizing these pitfalls is crucial for developing accurate and natural-sounding Spanish:- Omitting or Misplacing the Accent Mark: This is perhaps the most ubiquitous error. Writing
comiainstead ofcomíais orthographically incorrect and signals a misunderstanding of Spanish stress rules. The accent on theíis not optional; it dictates the correct pronunciation by marking the stressed syllable (co-MÍ-a) and distinguishes the Imperfect from other possible (and often non-existent) forms. Without it, the natural stress would fall elsewhere, usually the penultimate syllable, leading to mispronunciation.
- Confusing Imperfect with Preterite: This is the most fundamental and persistent challenge. The primary distinction lies in aspect: Imperfect for ongoing, habitual, or descriptive actions; Preterite for completed, single actions. A common error is using the Imperfect for a definite, completed past action:
Ayer comía pizza(Incorrect, implies 'I used to eat' or 'was eating' pizza yesterday as a habit, not a single meal). The correct form would beAyer comí pizza(I ate pizza yesterday). Always evaluate whether the action is viewed as a finished event (Preterite) or as a process, habit, or background (Imperfect).
- Applying
-arEndings to-er/-irVerbs: The Imperfect endings for-arverbs are-aba,-abas, etc. A typical beginner's mistake is to incorrectly apply these to-eror-irverbs, producing forms likecomabaorvivaba. This demonstrates a lack of awareness of the distinct conjugation patterns. Always recall that-erand-irverbs uniformly use the-íapattern in the Imperfect.
- Over-reliance on English
used toTranslation: Whileused tois a valid translation for habitual Imperfect actions, limiting its interpretation to only this phrase restricts understanding.Comíacan also meanI was eating(ongoing action) or simplyI atewhen the context is descriptive or highlights duration. For instance,Cuando era joven, comía muchotranslates well toWhen I was young, I used to eat a lot. However,Yo comía cuando me llamasteisI was eating when you called me. Do not force a single English equivalent onto the Imperfect, as its usage is broader.
- Incorrect
SerandEstarUsage: Bothser(era,eras, etc.) andestar(estaba,estabas, etc.) are irregular in the Imperfect. Learners often struggle with when to use each verb, a challenge that persists from the present tense. The core rules distinguishingser(inherent qualities, identity, origin, time) fromestar(temporary states, location, condition) remain constant. An error might beElla estaba mi hermana(incorrect, Ella era mi hermana) orLa casa era sucia(incorrect if temporary, La casa estaba sucia if temporary, La casa era sucia if inherently dirty).
Contrast With Similar Patterns
-er/-ir verbs is greatly enhanced by contrasting it with other past tense forms. The most critical distinction is with the Preterite tense, as they both describe past actions but from fundamentally different aspects.-ía for ER/IR verbs) | Preterite (e.g., comí, viví) |used to, was/were -ing, would (for habit), kept doing. | did, -ed (simple past), finished doing. |Ella leía el libro cuando él llegó. (She was reading...) | Ella leyó el libro anoche. (She read the book last night.) |Nosotros vivíamos en México en ese entonces. (We were living...) | Nosotros vivimos en México por un año. (We lived in Mexico for a year.) |he comido, has vivido) describes actions completed in the past but with a direct relevance to the present moment. The Imperfect, conversely, has no connection to the present; it functions entirely within a past context. Do not confuse He vivido aquí (I have lived here – implying I still do, or its effects are present) with Vivía aquí (I used to live here / was living here – no present implication).-ría):would for both habitual past actions (Imperfect) and hypothetical actions (Conditional), Spanish maintains a clear distinction. The Conditional tense (comería, viviría) translates to would eat or would live but exclusively expresses hypothetical situations, polite requests, or future actions from a past perspective (would do). It never describes habitual past actions.Cuando era niño, comería dulces cada día is incorrect for 'I used to eat candy each day'; it should be comía.estar + -ndo):estoy comiendo) describes an action happening now. While was/were -ing is a common translation for the Imperfect, it's crucial to understand that the past progressive (estaba comiendo) exists in Spanish for very specific emphasis on an action that was definitively in progress at a particular past moment. The simple Imperfect (comía) is broader and can encompass habit, description, or general duration, not just strict moment-by-moment progress.Yo comía pizza can mean 'I was eating pizza' or 'I used to eat pizza', while Yo estaba comiendo pizza strongly emphasizes 'I was (definitively) in the process of eating pizza'.Real Conversations
The Imperfect is ubiquitous in everyday Spanish, appearing naturally in various contexts from casual texting to more formal narratives. It provides the essential texture for conveying past experiences.
Scenario 1
- Amigo 1 (Texto): ¿Qué hacías cuando eras niño? (What did you used to do when you were a child?)
- Amigo 2 (Texto): Uf, corría por el parque, comía helado todos los días y veía muchos dibujos. (Ugh, I used to run through the park, I used to eat ice cream every day, and I used to watch lots of cartoons.)
- Here, corría, comía, veía depict habitual past actions and conditions.
Scenario 2
- Colega (conversación): ¿Cómo era tu primer trabajo? (What was your first job like?)
- Tú: Trabajaba en una cafetería pequeña. Siempre tenía mucha gente y los clientes eran muy amables. (I worked in a small cafe. It always had many people and the clients were very kind.)
- Trabajaba describes an ongoing past situation, tenía describes a continuous condition, and eran describes a characteristic of the clients.
Scenario 3
- Narrador: Era una noche oscura. La lluvia caía sin cesar y el viento silbaba entre los árboles. María sentía un miedo profundo. (It was a dark night. The rain was falling without ceasing and the wind was whistling through the trees. María felt a deep fear.)
- All Imperfect verbs here (era, caía, silbaba, sentía) create the descriptive background for the narrative.
Scenario 4
- Post: Cuando vivía en Madrid, siempre quería visitar el Prado. ¡Por fin lo hice! (When I was living in Madrid, I always wanted to visit the Prado. I finally did it!)
- Vivía describes an ongoing past residency, quería an enduring desire.
Progressive Practice
Effective learning of the Imperfect for -er/-ir verbs moves beyond simple conjugation drills. Focus on contextualized practice to internalize its nuanced usage:
- Storytelling: Narrate simple stories about your past, your childhood, or recent events. Consciously decide when to use the Imperfect for descriptions, habits, and ongoing actions, and when to switch to the Preterite for specific events. Start with phrases like Cuando era niño... or Antes....
- Daily Journaling (Past Tense Focus): Each day, write a few sentences describing what a typical day used to be like when you were younger, or describe a place you used to know. This forces continuous application of the Imperfect in a descriptive context.
- Picture Description: Find old photographs or images of scenes. Describe what was happening, what the people were wearing, how the weather was, or what objects were present using the Imperfect. Then, introduce a single event in the Preterite: Todos sonreían mientras el fotógrafo tomaba la foto.
- Contrast Exercises: Actively seek or create sentences where you must choose between the Imperfect and Preterite. For example, fill-in-the-blank exercises that provide context clues (e.g., siempre, todos los días for Imperfect; ayer, una vez for Preterite).
- Retellings: Watch a short video clip or read a brief story. Then, retell the events, paying close attention to which actions were ongoing (Imperfect) and which were completed (Preterite).
