How to see the pattern in Portuguese “Ir” verbs

Introduction

Learning how to recognize the pattern in Portuguese Ir verbs gives beginners a huge advantage. This article explains the regular and common irregular patterns for verbs ending in ir in Brazilian Portuguese, with clear examples, helpful vocabulary, quick tips, and common learner mistakes.

What are Ir verbs and why they matter

Verbs that end in ir make up one of three main verb groups in Portuguese, alongside -ar and -er verbs. Knowing the typical endings for ir verbs helps you build present tense conjugations, form simple commands, and understand infinitive phrases on menus, schedules, and signs.

Many everyday verbs you will see in Brazil are ir verbs, such as abrir (to open), partir (to leave/split), decidir (to decide), and a few irregulars like ir (to go) itself. Recognizing the pattern makes reading and basic conversation faster for beginners.

Core pattern: regular -ir verbs in the present tense

Most regular ir verbs follow one straightforward pattern in the present indicative. Start with the verb stem (remove -ir) and add these endings:

eu: -o

você/ele/ela: -e

nós: -imos

vocês/eles/elas: -em

Example with abrir (to open):
eu abro
você abre
nós abrimos
eles abrem

Simple examples you will encounter

Short practical sentences show how these forms appear in real contexts:

No restaurante: Nós abrimos às 12h. — We open at 12:00.

Mensagem de texto: Eu saio agora. — I leave now. (from sair, note: irregular)

Sinal na porta: Não abrir. — Do not open. (a shortened instruction)

In a schedule: O trem parte às 18h. — The train departs at 6 PM. (from partir)

Infinitive use: seeing ir on signs and menus

The infinitive form ending in ir appears on signs, menus, and instructions. Examples to recognize:

Entrar

Estacionar

Provar

Abrir

These tell an action in a general sense, often used for labels, instructions, or menu verbs like Pedir (to order) which is an -ir verb: Pedir com antecedência means order in advance.

Stem-changing and irregular -ir verbs to watch

Not all ir verbs are perfectly regular. A few common verbs change the stem slightly or are fully irregular. Learn these common ones first:

ir — to go (very irregular)
eu vou
você vai
nós vamos
eles vão

vir — to come (irregular stem in some forms)
eu venho
você vem
nós vimos
eles vêm

dormir — to sleep (regular endings but stem vowel shifts in some tenses; present is: eu durmo, você dorme, nós dormimos, eles dormem)

pedir — to ask/order (regular present: eu peço is irregular spelling change; note: in Brazilian Portuguese eu peço uses c-cedilla in other conjugations, but focus for beginners: eu peço, você pede, nós pedimos, eles pedem)

Practical sentence examples with irregulars

Eu vou ao mercado. — I go to the market.

Você vem comigo? — Are you coming with me?

Ele dorme cedo. — He sleeps early.

Eu peço água, por favor. — I ask for water, please.

Recognizing patterns beyond the present tense

Once you know present tense endings, similar patterns repeat in other simple forms. For example, the preterite (past) for many regular ir verbs uses -i and -imos endings:

eu parti — I left
nós partimos — we left

Notice how the stem often stays the same, and -imos appears both in present (nós abrimos) and preterite (nós partimos). Context tells you the tense.

Quick rules of thumb for beginners

Look at the final two letters: if the verb ends in ir, remove them to find the stem. Then add the present endings: -o, -e, -imos, -em.

If the verb feels irregular, learn the most common exceptions first: ir, vir, dormir, pedir, sair (to leave: eu saio, você sai, nós saímos, eles saem).

Many verbs learners need at first are regular, so mastering the basic pattern gives immediate usable skills for conversation and comprehension.

Common beginner mistakes and how to fix them

Mixing -er and -ir endings: Beginners often overgeneralize endings from -er verbs. Remember that for regular -er verbs the present endings differ (eu -o, ele -e, nós -emos, eles -em). Focus on the -nos form: -imos for ir vs -emos for er.

Forgetting irregular stems: Learn a short list of high-frequency irregulars rather than trying to guess. Make flashcards with eu, você, nós, eles forms for each.

Applying Brazilian pronunciation rules: Pronounce the final -r softly at the end of verbs in Brazil, often like an English h or almost silent in many regions. Hearing native audio helps you link forms to speech.

Useful beginner vocabulary with -ir verbs

abrir — to open

partir — to leave, to depart

decidir — to decide

assistir — to watch / attend (note: in Brazil assistir can mean both to watch TV and to attend an event)

cobrir — to cover

construir — to build (irregular in some forms: construir becomes eu construo; watch accent and pronunciation differences)

Short dialogues and realistic practice

At a café:

Pronunciation tips for beginners

Final -r in Brazilian Portuguese often sounds like a soft h or is nearly silent, especially in casual speech. So abrir may sound like abri(h) or abri. The stress usually stays on the syllable before the ending, so aprender vs abrir have different stress patterns you will internalize with listening.

Practice with audio resources or language apps focusing on Brazilian Portuguese to hear the differences between eu abro and eu abri (past). Listening to short dialogues helps connect forms to meaning.

When to focus on memorizing vs pattern recognition

Memorize the handful of highly irregular verbs first: ir, vir, sair, pedir, dormir. For the rest, rely on pattern recognition: remove -ir, learn the stem, and apply endings. This balance gets beginners speaking quickly while avoiding overwhelming memorization.

Use flashcards for irregular forms and reading practice for regular verbs. Simple real-life texts—menus, schedules, signs, messages—are great practice because they reuse common verbs in predictable contexts.

Resources and next steps

Use graded readers or phrasebooks for Brazilian Portuguese that highlight verb conjugations. Practice with short dialogues, listen to Brazilian podcasts or children’s videos, and try writing short messages using ir verbs: Eu abro a janela, Nós partimos agora, Ele pede água.

Try to spot ir verbs while traveling or using apps: on menus, look for Pedir; on doors, look for Abrir; on timetables, procurar Partir. These real contexts help cement pattern recognition quickly for beginners.

Conclusion

Understanding the pattern in Portuguese ir verbs gives beginners reliable building blocks for reading, speaking, and following signs and schedules in Brazilian Portuguese. Learn the regular endings, memorize a few frequent irregulars, practice with short real-life examples, and listen to native speech to connect forms with pronunciation and meaning.
