The Sentence I Got Wrong for a Year

I was telling a Brazilian friend about my childhood. I wanted to say "I lived in São Paulo when I was a kid," so I said "eu morei em São Paulo quando eu era criança." She tilted her head. "Morei? So you lived there once and left? Or you grew up there?"

I grew up there. Which meant the word was "morava," not "morei." Same verb, same past, but one of them says the whole thing was a finished event and the other says it was the backdrop of my childhood. I had been picking wrong for a year, and Brazilians had been quietly decoding what I actually meant the whole time.

If you have ever frozen mid-sentence trying to choose between "fiz" and "fazia," or "foi" and "era," this post is for you. Brazilian Portuguese has two everyday past tenses, and the choice between them is not random. There is one question that sorts almost every case.

Two Past Tenses, Two Different Jobs

English mostly gets by with one simple past. "I ate," "I lived," "I spoke." Portuguese splits that job in two.

The pretérito perfeito is your snapshot. It captures a finished action, something that started and ended. "What happened?"

The pretérito imperfeito is your movie camera rolling in the background. It shows an action in progress, a habit that repeated, or the scene around an event. "What was happening?" or "What used to happen?"

Listen to the same verb in both tenses:

"Eu morei no Rio" says you lived there for a defined stretch that is now closed: two years, a semester, one chapter. "Eu morava no Rio" sets a scene: back then, that was where your life happened, and something else is about to be told against that backdrop.

That is the whole idea. Everything below is just learning to feel which one a sentence wants.

The One Question That Decides It

Before the rules, here is the shortcut I wish someone had handed me on day one.

Ask yourself: can I put "and then" in front of the verb?

• "And then I arrived." → finished event → cheguei (perfeito)
• "I used to arrive early every day." → repeated habit, no single moment → chegava (imperfeito)

If the verb moves the story forward one step, it is perfeito. If the verb just describes how things were, sat still, or repeated on a loop, it is imperfeito. Hold onto that and most sentences sort themselves.

When to Use the Pretérito Perfeito

Reach for the perfeito when the action is done and boxed in. Five common cases:

1. A single completed action. "Ela falou com o chefe hoje de manhã." (She spoke with the boss this morning.) One event, over.
2. An action with a clear time frame, even a long one. "Eu morei no Rio por dois anos." (I lived in Rio for two years.) The two years are finished, so the box is closed.
3. A sequence of events in a story. "Nós fomos à praia e comemos pastel." (We went to the beach and ate pastel.) Each verb is one step forward.
4. A sudden event that interrupts something. "O telefone tocou." (The phone rang.) More on this pairing below.
5. The weather or a state, when it is treated as one finished stretch. "Choveu muito ontem à noite." (It rained a lot last night.) The rain started and stopped.

Words that often pair with the perfeito: ontem (yesterday), hoje (today, for something already done), na semana passada (last week), de repente (suddenly), em 2019 (in 2019).

When to Use the Pretérito Imperfeito

Reach for the imperfeito when you are painting the background instead of reporting an event. Five common cases:

1. Habits and routines in the past. "Todo domingo a gente almoçava na casa da minha avó." (Every Sunday we used to have lunch at my grandmother's house.) It happened over and over, so there is no single moment to point at.
2. Descriptions and states. "Ela falava três línguas fluentemente." (She spoke three languages fluently.) This describes how she was, not one thing she did.
3. Age, time, and weather as a backdrop. "Eu tinha vinte anos e fazia muito calor." (I was twenty and it was very hot.) Age and weather setting the scene, not moving the plot.
4. An action in progress in the past, usually with estar in the imperfeito plus the gerund. "Estava chovendo quando eu saí do trabalho." (It was raining when I left work.)
5. Emotions and mental states. "Eu queria ir, mas estava cansado." (I wanted to go, but I was tired.)

Words that often pair with the imperfeito: sempre (always), todo dia (every day), antigamente (in the old days), naquela época (back then), geralmente (usually), enquanto (while).

The Two Tenses Working Together

Here is where it clicks. Real stories use both tenses in the same breath. The imperfeito sets the stage, then the perfeito drops the event onto it.

"Eu estava dormindo quando o telefone tocou." (I was sleeping when the phone rang.)

The sleeping was already going, spread out in the background: imperfeito. The ring was a single sharp moment that cut in: perfeito. Almost every past-tense story in Portuguese is built from this pattern. Scene, then event. Camera rolling, then snapshot.

Compare the rain again, in both roles:

"Choveu ontem" reports the rain as a done thing. "Estava chovendo quando eu saí" makes the rain the wet backdrop to the real event, you leaving. Same rain, different job.

The Conjugations You Actually Need

Good news: the endings are regular for the huge majority of verbs, and the imperfeito is one of the easiest tenses in the whole language.

Pretérito perfeito, regular endings (eu / você-ele / nós / eles):

• -ar (falar): falei, falou, falamos, falaram
• -er (comer): comi, comeu, comemos, comeram
• -ir (partir): parti, partiu, partimos, partiram

Pretérito imperfeito, regular endings:

• -ar (falar): falava, falava, falávamos, falavam
• -er (comer): comia, comia, comíamos, comiam
• -ir (partir): partia, partia, partíamos, partiam

Notice the imperfeito only has two ending shapes: -ava for -ar verbs and -ia for -er and -ir verbs. That is basically the whole tense.

And here is the gift: the pretérito imperfeito has only four irregular verbs in the entire language.

• ser → era, era, éramos, eram
• ter → tinha, tinha, tínhamos, tinham
• vir → vinha, vinha, vínhamos, vinham
• pôr → punha, punha, púnhamos, punham

That is it. Even the notoriously messy verb ir is regular here (ia, ia, íamos, iam). The perfeito has more irregulars to memorize (fui, fiz, tive, quis, pude, and friends), but the imperfeito you can nearly master in an afternoon.

The Mistakes English Speakers Make Most

Using perfeito for childhood and habits. This was my São Paulo mistake. "When I was a kid I played soccer" is a repeated habit, so it is "eu jogava futebol," not "eu joguei." If it happened again and again, go imperfeito.

Translating "was + verb-ing" word for word. English "I was eating" is one idea, but in Portuguese it splits into estar (imperfeito) plus the gerund: "eu estava comendo." Do not try to force a single word to carry it.

Freezing on "era" vs "foi." Both come from ser. Use era to describe how something was ("a festa era grande," the party was big, as a general description) and foi for a finished verdict or event ("a festa foi ótima," the party was great, now that it is over). When you are describing the scene, lean imperfeito.

Overthinking it mid-conversation. Brazilians will understand you either way. The tense rarely blocks meaning, it just marks you as still learning. So say it wrong, get corrected, and move on. That loop is how the feel gets built.

Build the Feel, Not Just the Rules

Rules get you started, but the choice between perfeito and imperfeito eventually has to become a reflex. You will not have time to run the "and then" test in the middle of a real conversation. You need to have heard and said these patterns enough times that the right tense just falls out of your mouth.

That is the part reading cannot give you. It comes from telling actual stories, out loud, and getting corrected in the moment when you say "morei" and meant "morava."

This is one of the reasons we built Sotaque Brasileiro. The AI tutor lets you tell stories about your past and gently flags when the tense does not match what you mean, without the awkwardness of asking a friend to correct you for the tenth time. You practice the scene-then-event pattern in real sentences until it stops being a decision and starts being a habit.

Take the free placement test to see where your past tense stands. It takes about five minutes, and it will tell you fast whether the perfeito and imperfeito are already clicking or still need work.

Frequently Asked Questions

What is the difference between pretérito perfeito and imperfeito?

The pretérito perfeito describes a finished action with a clear start and end ("eu comi," I ate). The pretérito imperfeito describes an ongoing, habitual, or background action in the past ("eu comia," I used to eat / I was eating). Perfeito is a snapshot of an event; imperfeito is the camera rolling in the background.

When do you use the imperfect tense in Portuguese?

Use the imperfeito for past habits ("todo dia eu corria," every day I used to run), descriptions and states ("ela era alta," she was tall), age and weather as background ("eu tinha dez anos"), and actions in progress ("estava chovendo"). If the action repeated or set the scene rather than happening once, it is imperfeito.

Is pretérito perfeito the same as the English preterite?

Roughly, yes. The pretérito perfeito lines up with the English simple past for finished actions: "eu falei" = "I spoke." The tricky part is that English also uses the simple past for habits ("I used to speak" or "I would speak"), and Portuguese moves those into the imperfeito instead.

How do you conjugate the pretérito imperfeito?

For regular verbs, add -ava endings to -ar verbs (falava, falávamos, falavam) and -ia endings to -er and -ir verbs (comia, comíamos, comiam). Only four verbs are irregular in the imperfeito: ser (era), ter (tinha), vir (vinha), and pôr (punha). It is one of the most regular tenses in Portuguese.

Which past tense should I learn first?

Learn the pretérito perfeito first, since you use it to report anything that happened, which is most of everyday conversation. Then add the imperfeito for habits, descriptions, and storytelling. Once you can tell a simple story using both together (scene in imperfeito, events in perfeito), you have the core of the Brazilian Portuguese past tense.
