Introduction
Learning to write in Brazilian Portuguese involves more than memorizing vocabulary. Beginners and intermediate learners often make predictable mistakes when choosing everyday words, using accents, punctuation, and adjusting tone. This article explains common errors and gives practical sentence patterns, sample messages, and short writing exercises aimed at real-life contexts like shopping, travel, work messages, and casual chat.
Why common vocabulary mistakes happen
Many mistakes come from direct translation from English, false friends, missing accents, and ignoring register differences between formal and informal settings. Portuguese spelling and pronunciation influence how words are written, and small differences change meaning or sound unnatural to native readers.
Portuguese also relies on diacritics to mark stressed syllables and vowel quality. Omitting them can create different words or confuse readers. In short writing—messages, labels, forms—errors multiply because learners rush or rely on phonetic guessing.
Key categories of everyday mistakes
Focus on these common areas: false cognates, accent and vowel errors, word order differences, preposition choices, informal vs formal vocabulary, contractions and clitics, and punctuation in questions and greetings.
False friends and similar-looking words
Some Portuguese words look like English words but mean something else. Confusing them leads to embarrassing or confusing messages.
Examples:
actual -> atual
Correct: O preço atual é mais baixo.
assist -> assistir (to watch) vs ajudar (to help)
Correct: Eu vou assistir ao filme. / Você pode me ajudar?
pretend -> pretender (to intend) vs fingir (to pretend)
Correct: Eu pretendo viajar amanhã. / Ela fingiu que estava doente.
Accents and vowel errors that change meaning
Portuguese uses acute and circumflex accents and the tilde. Missing or wrong accents can change meaning or produce nonwords.
Common beginner errors and corrections:
avô vs avo vs avó
Correct: Meu avô mora no sul. / Minha avó cozinha bem.
é vs e vs se
Correct: Ele é médico. / Eu e você vamos. / Se chover, fico em casa.
maçã vs maca
Correct: Comprei uma maçã. (maca is stretcher)
Word order: adjectives and placement
Portuguese often places adjectives after nouns, unlike English. Beginners may translate literally, producing unusual orders.
Typical error: bonito casa
Correct: casa bonita
Example sentence: A casa é bonita.
Some adjectives come before for emphasis or idiomatic use. Learn common pairs and practice patterns.
Example practice: bom dia vs dia bom
Correct: bom dia (greeting). Dia bom is uncommon in greetings.
Prepositions: choosing the right one
Prepositions cause many small errors because Portuguese uses different prepositions than English in certain verbs and expressions.
Examples:
arrive in -> chegar em vs chegar a
Correct: Cheguei em São Paulo. / Cheguei a uma conclusão.
listen to -> ouvir vs escutar + a (less common)
Correct: Eu ouvi a música. / Eu escutei a música.
depend on -> depender de
Correct: Dependo do transporte público.
Formality and tone in messages and emails
Choosing between tu and você, or using formal greetings, matters. In Brazil, você is common in most regions; tu appears regionally. For learners, use você unless you know the local usage.
Email openings and closings:
Informal: Oi Maria, tudo bem? / Abraços, João
Formal: Prezada Sra. Silva, / Atenciosamente, João Silva
Using the wrong register in a job email or with older people feels impolite. Practice set phrases to match contexts.
Practical sentence patterns for everyday contexts
Below are templates and short examples beginners can use and adapt. Replace bracketed parts with your information.
Shopping and restaurants
Quero [item], por favor. Ex: Quero uma água sem gás, por favor.
Quanto custa [item]? Ex: Quanto custa esta blusa?
Você aceita cartão? Ex: Vocês aceitam cartão de crédito?
Travel and directions
Onde fica [place]? Ex: Onde fica a estação de metrô?
Como eu chego a [place]? Ex: Como eu chego ao aeroporto?
Tem ônibus para [place]? Ex: Tem ônibus para o centro?
Work and scheduling

Vou chegar atrasado. Ex: Desculpe, vou chegar 15 minutos atrasado.
Por favor, envie o arquivo. Ex: Por favor, envie o arquivo até sexta.
Casual chat and messaging

Short email and message examples beginners can copy
Informal message to a friend:
Oi Ana, tudo bem? Estou chegando amanhã às 14h. Queremos almoçar no centro? Abraços, Pedro
Formal email to a teacher:
Prezada Professora Silva, bom dia. Não pude comparecer à aula ontem. Poderia me enviar os materiais? Atenciosamente, Lucas Souza
Simple request at a store:
Com licença, você pode me mostrar outra cor deste casaco? Obrigado(a).
Common punctuation and capitalization pitfalls
Portuguese punctuation rules are similar but have small differences. Learn these practical points for clear writing.
Question marks: Always use a question mark at the end of direct questions. In informal chat, learners sometimes omit them. Example: Você vai ao mercado?
Commas: Use commas to separate clauses and items. Avoid comma splices by using conjunctions or separate sentences. Example: Fui ao mercado, comprei pão e voltei para casa.
Capitalization: Days of the week, months, and languages are not capitalized in Portuguese. Beginners often write them with capitals from English. Example: terça-feira, março, português.
Contractions and clitics: practical use in writing
Portuguese has contractions that are common in speech and writing. Learning them makes messages more natural.
Examples:
de + o = do; em + o = no
Correct: O livro do aluno. / Estou no mercado.
para + o = para o or pro (informal)
Correct formal: Vou para o trabalho.
Informal: Vou pro trabalho.
me + verb -> me + verbo (placement matters in formal writing)
Correct informal chat: Me ajuda? Formal: Você pode me ajudar?
Everyday accent and spelling practice exercises
Practice small writing tasks focused on accents and common words. Set a timer for 10 minutes and write short messages using the prompts below.
Prompts:
Write a shopping list with five items, using accents where needed. Example: pão, maçã, açúcar, café, queijo.
Write a short message asking to reschedule a meeting. Include a day and time. Example: Desculpe, posso remarcar a reunião para quinta às 16h?
Write a polite request to a hotel: Example: Bom dia, tenho uma reserva no nome Silva. É possível solicitar um quarto mais silencioso?
Common beginner mistakes with quick corrections
Wrong: Eu tenho 20 anos de idade.
Better: Tenho 20 anos. (Both work, but native speakers often omit de idade)
Wrong: Eu gosto muito de jogar futebol em o parque.
Correct: Eu gosto muito de jogar futebol no parque.
Wrong: Você fala Inglês?
Correct: Você fala inglês? (lowercase inglês)
Wrong: Vou na loja.
Correct: Vou à loja. or Vou na loja. (Note: na = em + a is common; use à when direction + article fits: Vou à loja is standard)
Tips to avoid these mistakes in real writing
Use simple templates first: memorize a few ready-made sentences for common situations and adapt them. This reduces errors from on-the-spot translation.
Study small sets of false friends and accents each week. Focused lists help retention and reduce incorrect word choices.
Read short real texts in Brazilian Portuguese: menus, signs, chat messages. Notice word order, contractions, and punctuation.
When in doubt, choose the simpler construction. For example, use você + verb, prefer no contractions if you are unsure, and avoid complex prepositions until comfortable.
Conclusion
Mastering everyday vocabulary choices in Brazilian Portuguese is a mix of learning specific patterns, recognizing false friends, and practicing accent and preposition use. Use the provided templates and short exercises in real-life contexts: shopping, travel, work, and chat. With targeted practice on the common mistakes outlined here, your written Portuguese will become clearer, more natural, and easier for native speakers to read.
