Past Actions with -ir Verbs (Pretérito Perfeito)
Grammar Rule in 30 Seconds
To talk about completed actions with -ir verbs, remove the -ir and add the specific past tense endings for each person.
- For 'eu', add -i: Partir -> Part-i (I left).
- For 'você/ele/ela', add -iu: Partir -> Part-iu (He/she left).
- For 'nós', add -imos: Partir -> Part-imos (We left).
Overview
In Portuguese grammar, the Pretérito Perfeito (Simple Past, often called the Preterite) is the primary tense used to talk about actions that were started and completed at a specific point in the past. It's the tense you use to narrate events, recount a story, or state a fact that is finished and done. Think of it as a snapshot of a past event.
Its function is to say, "This happened."
This guide focuses specifically on regular verbs ending in -ir. This group, which includes common verbs like abrir (to open), partir (to leave), and decidir (to decide), follows a highly predictable conjugation pattern. For learners at the A2 level, mastering this pattern is a crucial step toward building coherent narratives about past experiences.
Unlike irregular verbs, which require significant memorization, regular -ir verbs provide a stable framework. Once you learn the set of endings, you can apply them to hundreds of verbs.
The Pretérito Perfeito is one of two fundamental past tenses in Portuguese. It contrasts with the Pretérito Imperfeito (Imperfect), which describes ongoing or habitual past actions. The Perfeito is about the event, while the Imperfeito is about the scene.
For now, we will focus solely on the Perfeito to describe those single, completed actions. For example, Eu decidi não ir à festa (I decided not to go to the party) presents the decision as a single, concluded mental act.

How This Grammar Works
Pretérito Perfeito operates on the grammatical principle of perfective aspect. This is a technical term for viewing an action as a complete, bounded event. Imagine you are looking at a timeline of the past; the Pretérito Perfeito places a single, solid dot on that timeline.Eu acordei, levantei e abri a janela. (I woke up, I got up, and I opened the window.) Each action is a self-contained, completed step in a sequence.Ela partiu às cinco horas (She left at five o'clock), you are reporting a finished event. There is no implication that she is still in the process of leaving or that the action has any direct relevance to the present moment, other than as a piece of information.Formation Pattern
-ir verb in the Pretérito Perfeito is a simple, mechanical two-step formula. This predictability is what makes regular verbs a cornerstone of learning the tense.
-ir ending from the verb's infinitive form.
dividir (to divide) → divid-
cumprir (to fulfill/accomplish) → cumpr-
insistir (to insist) → insist-
Pretérito Perfeito Ending
decidir (to decide):
decidir | decid- | Eu | decid- + -i | Eu decidi |
decidir | decid- | Ela | decid- + -iu | Ela decidiu |
decidir | decid- | Nós | decid- + -imos | Nós decidimos |
decidir | decid- | Eles | decid- + -iram | Eles decidiram |
proibir (to prohibit). You can immediately deduce eles proibiram (they prohibited) and eu proibi (I prohibited).
When To Use It
Pretérito Perfeito is used in specific contexts, almost always tied to the idea of completion. You should use it for:- 1A single, concluded action in the past. This is its most common use. The action happened once and is finished.
Eu abri o email.(I opened the email.)O gato subiu na árvore.(The cat climbed the tree.)
- 1A sequence of completed past actions. This is how you build a narrative.
Ele entrou na loja, comprou o pão e partiu imediatamente.(He entered the store, bought the bread, and left immediately.)
- 1An action that occurred during a specific, finished period of time. Even if the action itself lasted for a while, the time frame in which it happened is now closed.
Nós discutimos o projeto por três horas.(We discussed the project for three hours.)Eles viveram em Lisboa durante a década de 90.(They lived in Lisbon during the 90s.)
- 1An action that happened a specific number of times.
Eu assisti a esse filme duas vezes.(I watched this movie twice.)
Pretérito Perfeito. Look for these time markers:ontem(yesterday)anteontem(the day before yesterday)na semana passada(last week)no mês passado(last month)no ano passado(last year)em 2015(in 2015)de repente/de súbito(suddenly)
Common Mistakes
- 1Confusing the
nósform:partimos(present) vs.partimos(past). For regular-irverbs, the conjugation fornósis identical in the present tense and thePretérito Perfeito.
Nós partimos para o Rio amanhã.(We leave for Rio tomorrow.) - Present (indicated byamanhã)Nós partimos para o Rio ontem.(We left for Rio yesterday.) - Past (indicated byontem)
agora, sempre, ontem, na semana passada) to understand if nós dividimos means "we divide" or "we divided."- 1Incorrect ending for
ele/ela/você:-ioinstead of-iu. A very frequent error is to write or say something likeele abrio. The correct ending is-iu. The sound is a quick diphthong, not two separate vowels.
- Incorrect:
*Ela decidio - Correct:
Ela decidiu
- 1Over-regularizing irregular verbs. Once you learn this clean pattern, it's tempting to apply it to every
-irverb. However, some of the most common-irverbs are irregular. For example,vir(to come) does not follow the pattern.
- Incorrect:
*Ele viu para a festa.(Applying the pattern tovir) - Correct:
Ele veio para a festa.
ir (to go), ser (to be), and vir (to come) separately. Do not apply the regular -ir endings to them.- 1Pronunciation of
-iramvs.-irão. The third-person plural ending-iram(as ineles partiram) is often confused with the future tense ending-irão.
partiram(past): The stress is on the second-to-last syllable (par-TI-ram), and the final-amis a weak, nasal sound, almost like "-own" in English.partirão(future): The stress is on the final syllable (par-ti-RÃO), and the-ãois a strong, nasal diphthong.
Contrast With Similar Patterns
Pretérito Perfeito and the Pretérito Imperfeito (Imperfect). Using the wrong one is a clear sign of a non-native speaker. They are not interchangeable.Pretérito Perfeito (The Snapshot) | Pretérito Imperfeito (The Scenery/Video) |De repente, o telefone tocou. (Suddenly, the phone rang.) | O telefone tocava sem parar. (The phone was ringing non-stop.) |Eu abri a janela. (I opened the window. - A single action) | A janela estava aberta. (The window was open. - A state/description) |Ela comeu o bolo. (She ate the cake. - It's gone.) | Ela comia bolo todos os dias. (She used to eat cake every day. - A habit) |Era uma noite fria e as pessoas andavam rapidamente pelas ruas. (It was a cold night and people were walking quickly through the streets.)De repente, eu ouvi um grito e decidi ver o que era. (Suddenly, I heard a scream and decided to see what it was.)Pretérito Perfeito often covers the meaning of both the Simple Past and the Present Perfect.Eu já comi.can translate to "I already ate" (Simple Past) or "I have already eaten" (Present Perfect).Você já assistiu a este filme?means "Have you ever watched this movie?"
Pretérito Perfeito is the correct choice.Real Conversations
Textbook examples are clean, but real language is often faster and more direct. Here’s how you'll see the Pretérito Perfeito with -ir verbs in the wild.
On WhatsApp or Social Media:
- Person A: E aí, conseguiu o ingresso? (So, did you get the ticket?)
- Person B: Consegui! A gente dividiu o custo. (I got it! We split the cost.)
- Person A: Boa! Já partiu pra lá? (Nice! Have you left for there yet?)
- Person B: Parti agora msm. (Leaving right now. msm = mesmo)
Notice the directness. The questions and answers are short and focused on completed actions.
Casual Spoken Portuguese:
- Nossa, eu assisti um documentário incrível ontem à noite. Abriu minha mente. (Wow, I watched an incredible documentary last night. It opened my mind.)
- Sério? Sobre o quê? Eu não vi nada. Eu dormi cedo. (Really? About what? I didn't see anything. I slept early.)
Here, assisti, abriu, and dormi are all snapshots of last night's events.
In a Work Context (Email/Slack):
- Olá equipe, já dividi as tarefas para o novo projeto. Todos receberam o convite para a reunião? (Hello team, I have already divided the tasks for the new project. Did everyone receive the meeting invitation?)
- Sim, recebi. Você incluiu o feedback do cliente? (Yes, I received it. Did you include the client's feedback?)
Again, the tense confirms completed professional actions: the tasks were divided, the invitation was received.
Progressive Practice
To internalize this pattern, work through these exercises, moving from simple mechanics to more complex application.
Step 1: Mechanical Conjugation
Take the verb cumprir (to fulfill/accomplish) and write out its full conjugation in the Pretérito Perfeito for eu, você, ela, nós, and eles.
Step 2: Fill in the Blank
Complete these sentences with the correct Pretérito Perfeito form of the verb in parentheses.
Eu ______ (abrir) a porta para o carteiro.
Nós ______ (decidir) viajar nas férias.
Ontem, eles ______ (assistir) ao jogo de futebol.
Você já ______ (dividir) o documento com a equipe?
Step 3: Create Your Own Sentences
Write three original sentences about things you did yesterday. Use a different regular -ir verb in each one. Examples: partir, discutir, cumprir.
Step 4: Build a Narrative
Write a short paragraph (3-4 sentences) describing a sequence of actions. For example, describe making a simple decision. Start with Ontem à noite... and use at least two -ir verbs in the Pretérito Perfeito.
Step 5: Contextual Choice
Choose the correct verb tense (Present or Pretérito Perfeito) based on the context.
No ano passado, nós ______ (viajar) para o Brasil.
Normalmente, eu ______ (dividir) a conta com meus amigos.
Agora mesmo, ela ______ (partir) de casa.
Quick FAQ
nós form for -ir verbs really identical in the present and past?Yes, it is one of the quirks of the language. Nós abrimos can mean "we open" or "we opened." The same is true for -ar verbs (nós falamos). Only context, especially time markers like hoje versus ontem, can tell you which is which.
parti and partiu?The subject. The -i ending is exclusively for eu (I). Eu parti. The -iu ending is for ele (he), ela (she), and você (you). Ela partiu. Mixing these up is a very common mistake, so pay close attention to that final vowel.
-ir verb I learn is regular or irregular in the Pretérito Perfeito?There is no foolproof trick. The vast majority of -ir verbs are regular. The best strategy is to learn the regular pattern thoroughly and then memorize the handful of very common irregulars as exceptions (e.g., ir/ser, vir, pôr, dizer, fazer). When in doubt, try the regular pattern first; you will be right most of the time.
assistir o jogo but Portuguese people say assistir ao jogo?This is a grammar point called regência verbal (verb transitivity). In formal and European Portuguese, the verb assistir meaning "to watch" requires the preposition a (assistir a algo). In informal Brazilian Portuguese, this preposition is often dropped. Both Eu assisti ao filme (formal/EP) and Eu assisti o filme (informal BP) are common.
