Past Habits: Portuguese Imperfect Tense (-er & -ir Verbs)
Grammar Rule in 30 Seconds
Use the imperfect tense to describe repeated actions or states in the past, specifically for -er and -ir verbs.
- Remove the -er/-ir ending from the infinitive.
- Add the suffix -ia to the stem for all persons (eu, você, ele/ela).
- Remember the plural forms end in -iam (nós -íamos, vocês/eles -iam).
Overview
The Portuguese Imperfect Tense, known as the Pretérito Imperfeito do Indicativo, serves a crucial role in describing past events from a continuous or habitual perspective. Unlike the Pretérito Perfeito, which marks actions as completed, the Imperfect focuses on the duration, repetition, or general state of affairs in the past. It provides the background, the atmosphere, and the recurring elements of a past narrative, rather than its specific, delimited events.
Think of the Imperfect as the tense that answers questions like "What was happening?" or "What used to happen?" It's less about specific start and end points and more about the ongoing nature or the regularity of an action or condition. For regular verbs ending in -er and -ir, a significant simplification occurs: they share identical conjugation endings, making this tense particularly accessible once the pattern is learned. This consistency allows learners to apply a single set of endings across a broad range of verbs.

How This Grammar Works
Eu lia um livro (I was reading a book / I used to read a book) and Eu li um livro (I read a book [and finished it]). The first emphasizes the process or habit; the second, the completion. The Imperfect allows you to paint a continuous picture of the past, describing conditions, mental states, or activities that formed the backdrop for other events.were at a certain point in the past. It enables a nuanced portrayal of temporal relationships, allowing speakers to distinguish between actions that were in progress (chovia - it was raining) and those that happened suddenly or definitively (choveu - it rained [a specific event]).Formation Pattern
Pretérito Imperfeito for regular -er and -ir verbs involves a straightforward, three-step process. This pattern is exceptionally reliable for these verb categories, making it one of the most predictable conjugations in Portuguese grammar.
-er or -ir. For instance, correr (to run) or subir (to climb).
-er or -ir from the infinitive to reveal the verb's stem. For correr, the stem is corr-. For subir, the stem is sub-.
-er and -ir verbs. For example, eu corria (I used to run / I was running) or nós subíamos (we used to climb / we were climbing).
ser (to be), ter (to have), vir (to come), and pôr (to put). All other -er and -ir verbs follow the regular pattern presented here. Understanding this consistent formation is foundational for accurate and fluent communication about past events.
When To Use It
Pretérito Imperfeito is deployed in several distinct contexts to convey specific nuances about past actions and states. Its usage hinges on whether you intend to describe continuity, habit, or background, rather than a single, completed event.- Habitual or Repeated Actions in the Past: Use the Imperfect for actions you performed regularly or repeatedly in a past period. These are actions that occurred multiple times, forming a routine or habit.
Quando eu era criança, nós visitávamos a praia todos os verões.(When I was a child, we used to visit the beach every summer.)Ele sempre lia o jornal enquanto tomava café.(He always used to read the newspaper while he drank coffee.)
- Ongoing or Continuous Actions in the Past: This tense describes actions that were in progress at a particular moment in the past, often serving as background to another event (which may be expressed in the
Pretérito Perfeito). Ela escrevia uma carta quando o telefone tocou.(She was writing a letter when the phone rang.)Nós aprendíamos português quando a professora entrou.(We were learning Portuguese when the teacher entered.)
- Descriptions of Past States, Conditions, or Characteristics: The Imperfect is crucial for painting a picture of the past—describing weather, time, age, emotions, physical appearance, or general situations.
Era inverno e chovia muito naquela semana.(It was winter and it was raining a lot that week.)A casa tinha três quartos e parecia muito antiga.(The house had three bedrooms and seemed very old.)
- Setting the Scene in Narratives: When telling a story, the Imperfect establishes the initial conditions, mood, and descriptive elements before the main actions (often in
Pretérito Perfeito) unfold. O sol nascia, os pássaros cantavam e a cidade dormia.(The sun was rising, the birds were singing, and the city was sleeping.)
- Polite Requests (Brazilian Portuguese): In informal Brazilian Portuguese, the Imperfect of
querer(queria) is frequently used to make polite requests, softening the directness ofEu quero(I want). Eu queria um café com leite, por favor.(I would like a coffee with milk, please.) This implies a polite desire rather than a direct command.
Common Mistakes
Pretérito Perfeito, are frequent sources of error for learners. Recognizing these patterns and understanding why they are incorrect is key to mastering this aspect of Portuguese.- Confusing Imperfect with Preterite for Habitual Actions: A common pitfall is using the
Pretérito Perfeitofor actions that occurred repeatedly. For example,Eu comi pizza todos os sábados(Incorrect: I ate pizza every Saturday, implying a single event of 'eating pizza every Saturday') should beEu comia pizza todos os sábados(Correct: I used to eat pizza every Saturday).
- Omitting Accents in
nósandvósForms: Forgetting the accent mark on theíin forms likenós vivíamosorvós abríveisis a common orthographical error. These accents are not merely decorative; they indicate the stressed syllable and are essential for correct pronunciation and grammar.
- Using Imperfect for Single, Completed Past Events: The Imperfect should not be used for actions that occurred once and were completed at a specific past point. For instance,
Ontem, eu vendia meu carro(Incorrect: Yesterday, I was selling my car) is incorrect if the car was actually sold. The correct form isOntem, eu vendi meu carro(Yesterday, I sold my car).
- Misinterpreting
irforms:iavs.fui: The verbir(to go) frequently causes confusion.Eu iais the Imperfect, meaning "I was going" or "I used to go".Eu fuiis thePretérito Perfeito, meaning "I went". UsingEu fui à escola todos os dias(Incorrect: I went to school every day) suggests you completed the single act of going to school every day. The correct usage isEu ia à escola todos os dias.
