Irregular Preterites in Portuguese
Pretéritos Irregulares
This article is part of the Portuguese grammar tree on Settemila Lingue.
In Brief
Several very common Portuguese verbs have irregular forms in the pretérito perfeito simples, the tense used for completed past events. Instead of applying the regular endings mechanically, learn forms such as fui (I went/I was), tive (I had), fiz (I did/made), disse (I said), and pude (I managed to/could on one occasion). These forms normally describe an action or state as a completed whole.
Overview
The Portuguese pretérito perfeito simples, often called the preterite in English-language learning materials, presents a past event as completed: Ontem fiz o jantar means “Yesterday I made dinner.” Most verbs follow regular patterns, but some of the most frequent verbs do not. Because verbs such as ser, ir, ter, fazer, and poder appear constantly in everyday conversation, their irregular forms are essential at A2.
English also has high-frequency irregular past forms—went, was, had, did, and said. Portuguese differs in one important respect: each person (the speaker, listener, or person being discussed) has its own verb form. You therefore need more than one past form for each verb. The good news is that several irregular verbs share endings, and the subject pronoun is often unnecessary because the ending identifies the subject.
The core beginner task is to recognize and use the most common forms for single, completed events. Later, you will learn finer contrasts with the imperfect (a past tense commonly used for background, habits, and ongoing states) and some meaning changes that certain verbs have in the preterite.
How It Works
The basic sentence pattern
A typical statement follows this pattern:
subject (often omitted) + irregular preterite + rest of the sentence
- (Eu) fiz o almoço. — I made lunch.
- (Nós) tivemos um problema. — We had a problem.
- Eles vieram cedo. — They came early.
Portuguese often leaves out eu, nós, and other subject pronouns when the verb ending makes the meaning clear. Negation is straightforward: put não before the verb—Não pude ir (“I could not go”).
Core conjugations
The table below contains the ten core verbs in this concept. Você, ele, and ela use the same form; vocês, eles, and elas also share a form.
| Person | ser / ir | estar | ter | fazer | dizer |
|---|---|---|---|---|---|
| eu | fui | estive | tive | fiz | disse |
| tu | foste | estiveste | tiveste | fizeste | disseste |
| você / ele / ela | foi | esteve | teve | fez | disse |
| nós | fomos | estivemos | tivemos | fizemos | dissemos |
| vocês / eles / elas | foram | estiveram | tiveram | fizeram | disseram |
| Person | vir | poder | pôr | saber | trazer |
|---|---|---|---|---|---|
| eu | vim | pude | pus | soube | trouxe |
| tu | vieste | pudeste | puseste | soubeste | trouxeste |
| você / ele / ela | veio | pôde | pôs | soube | trouxe |
| nós | viemos | pudemos | pusemos | soubemos | trouxemos |
| vocês / eles / elas | vieram | puderam | puseram | souberam | trouxeram |
These paradigms reveal useful families:
- estar, ter: estive/esteve/estiveram and tive/teve/tiveram
- fazer, dizer, trazer: first-person forms ending in -z, -sse, or -xe, with third-person plurals in -eram
- poder, pôr, saber: short changed stems—pud-, pus-, soub-
- vir: vim, veio, vieram must be learned as a set
Do not attach regular endings to the infinitive. Forms such as faziu or podeu are not standard Portuguese forms of these verbs.
One set of forms, two verbs: ser and ir
Ser (“to be”) and ir (“to go”) have exactly the same preterite forms: fui, foste, foi, fomos, foram. Context supplies the meaning:
- Fui ao banco. — I went to the bank.
- A reunião foi longa. — The meeting was long.
A destination introduced by a or para usually points to ir. A description, identity, or evaluation usually points to ser.
Stress and written accents
Most forms have no written accent, but two third-person singular forms deserve attention:
- pôde = he/she/you formal could, was able to (past)
- pode = he/she/you formal can (present)
- pôs = he/she put (past)
The circumflex in pôde distinguishes past from present in writing. The infinitive pôr also keeps its circumflex, while forms such as pus and puseram do not.
Questions and objects
Portuguese does not add an equivalent of English did to make preterite questions. Intonation or a question word is enough:
- O que fizeste? — What did you do? (informal singular tu)
- Quando vocês vieram? — When did you all come?
An object pronoun (a short word standing for the person or thing affected by the action) may accompany the verb: Disseram-me a verdade means “They told me the truth.” Pronoun position varies by region and context; the irregular verb itself does not change.
Examples in Context
| Portuguese | English | Note |
|---|---|---|
| Fui ao cinema ontem. | I went to the cinema yesterday. | ir, completed trip |
| A festa foi ótima. | The party was great. | ser, evaluation |
| Estivemos em Lisboa durante três dias. | We were in Lisbon for three days. | Bounded stay |
| Tive uma reunião de manhã. | I had a meeting in the morning. | ter, completed past situation |
| Ela fez o jantar para todos. | She made dinner for everyone. | Third-person fez |
| Fez bom tempo no fim de semana. | The weather was good at the weekend. | Common weather use of fazer |
| Disseram-me a verdade. | They told me the truth. | Object pronoun after the verb |
| Eu disse que chegaria cedo. | I said that I would arrive early. | First-person disse |
| Os meus amigos vieram de comboio. | My friends came by train. | Third-person plural vieram |
| Não pude vir à reunião. | I could not come to the meeting. | A specific failed possibility |
| Finalmente pudemos entrar. | We were finally able to enter. | Successful opportunity |
| Pus as chaves em cima da mesa. | I put the keys on the table. | First-person pus |
| Só soube da notícia ontem. | I only found out about the news yesterday. | soube often means “found out” |
| O Rui trouxe café para o escritório. | Rui brought coffee to the office. | Third-person trouxe |
| Onde vocês estiveram? | Where were you? | Plural vocês, estiveram |
Common Mistakes
Building an irregular form from the regular pattern
- Wrong: Ela fazeu o jantar.
- Right: Ela fez o jantar.
- Why: Fazer changes its stem in the preterite. Its third-person singular is fez, not a regularized form.
Confusing present pode with past pôde
- Wrong: Ontem ele não pode entrar.
- Right: Ontem ele não pôde entrar.
- Why: Pode is present; pôde is the third-person singular preterite. The written accent marks the difference.
Assuming fui always means “went”
- Wrong interpretation: O filme foi interessante = “The film went interesting.”
- Right interpretation: O filme foi interessante = “The film was interesting.”
- Why: Foi belongs to both ir and ser. Use the surrounding words to decide which verb is meant.
Using the infinitive after English-style “did”
- Wrong: Você fez ir ao mercado?
- Right: Você foi ao mercado?
- Why: Portuguese forms a normal past question with the conjugated verb. It does not use an auxiliary equivalent to English did.
Choosing the wrong person ending
- Wrong: Nós tiveram um problema.
- Right: Nós tivemos um problema.
- Why: Nós requires the first-person plural form tivemos. Tiveram belongs with vocês/eles/elas.
Translating “knew” mechanically as soube
- Potentially wrong: Quando era criança, soube nadar.
- Better: Quando era criança, sabia nadar. — When I was a child, I knew how to swim.
- Why: Soube often means “found out” or came to know at a particular moment. Sabia, the imperfect, normally describes knowledge or ability that already existed over a period.
Usage Notes
Brazilian and European Portuguese
The conjugations above work across the major standards, but preferred pronouns differ. In much of Brazil, você/vocês are common, so third-person forms such as você fez and vocês fizeram are especially useful. Tu is also widely used in several Brazilian regions, sometimes with regional patterns of agreement. In Portugal, tu fizeste is normal in informal singular address; speakers often avoid an explicit você, while still using third-person verb forms in suitable forms of address.
European Portuguese commonly places an unstressed object pronoun after an affirmative preterite verb: Disseram-me a verdade. In conversational Brazilian Portuguese, Me disseram a verdade is very common. This difference concerns pronoun placement, not the conjugation of dizer.
Traditional tables may include vós forms such as fostes, estivestes, tivestes, and fizestes. Modern everyday speech rarely uses vós except in limited regional, religious, historical, or ceremonial settings. At A2, prioritize tu, você, nós, and vocês.
Preterite versus imperfect
Use the irregular preterite when you view the event as complete or bounded:
- Estive doente durante uma semana. — I was ill for a week.
- Tive dois empregos naquele ano. — I had two jobs that year.
Use the imperfect for background, repeated situations, or states without a highlighted endpoint:
- Estava doente quando telefonaste. — I was ill when you called.
- Tinha muito tempo livre naquela época. — I had a lot of free time then.
The distinction is not simply English “was” versus “was.” English often uses the same past form where Portuguese chooses between estive/estava, tive/tinha, or fui/era according to how the speaker presents the situation.
Beyond the Basics / Advanced Use
You do not need to master every nuance yet, but several of these verbs can change meaning when the preterite highlights a result or a moment of discovery.
| Preterite | Frequent meaning in context | Contrast |
|---|---|---|
| soube | found out, learned | sabia: knew, was aware |
| pude | was able to, managed to | podia: could, had the ability or permission |
| não pude | could not, was unable to on that occasion | não podia: was not able/allowed as an ongoing condition |
| tive de | had to, and presents the obligation as a completed event | tinha de: had to as background or an ongoing obligation |
| quis | wanted; in context, made a definite attempt or decision | queria: wanted, often softer or ongoing |
With poder, context determines whether the opportunity led to an actual result. Finalmente pude falar com ela strongly suggests that the conversation became possible and normally that it happened. In a negative sentence, não pude falar com ela states that the attempt or opportunity failed.
Some forms are easy to confuse even though they belong to different verbs. Viemos means “we came” (preterite of vir), while vimos means either “we see” or “we saw” (present or preterite of ver, depending on context). Likewise, fomos may mean “we were” or “we went.” Natural Portuguese tolerates genuine overlaps because the rest of the sentence is usually decisive.
In narratives, the preterite moves the sequence of events forward: Cheguei, pus a mala no quarto e fui jantar (“I arrived, put the suitcase in the room, and went to dinner”). The imperfect instead supplies the scene around those events: Estava cansado e fazia frio (“I was tired and it was cold”). Learning this foreground/background contrast will become important beyond A2.
Practice Tips
- Learn forms in short person sets. Start with eu–você/ele/ela–nós–vocês/eles/elas: fiz–fez–fizemos–fizeram. Add tu according to the variety of Portuguese you use. Saying a whole set helps you notice the shared stem.
- Pair each form with a time marker and a real event. Make sentences with ontem, na semana passada, and em 2025: Ontem tive muito trabalho; depois fiz o jantar. Personal memories are easier to retain than isolated lists.
- Practice contrasts, not just translations. Write pairs such as estive/estava, tive/tinha, and soube/sabia. Ask whether the sentence reports a completed event, a discovery, or background information before choosing the tense.
