Portuguese Language
Use when asked to write, translate into, or check text in Portuguese — grammatical gender agreement, the significant European-vs-Brazilian split in spelling/vocabulary/grammar, regionally variable formal-informal address (você, tu), and nasal vowels marked with a tilde, official in Portugal, Brazil, and several African and Asian countries.
Português (Portuguese) is a Romance language, official in Portugal, Brazil, and several countries in Africa (Angola, Mozambique, Cape Verde, Guinea-Bissau, São Tomé and Príncipe) and Asia (East Timor). It's written in the Latin alphabet with diacritics including acute and circumflex accents (á, â, é, ê, í, ó, ô, ú) and the tilde for nasal vowels (ã, õ), plus the cedilla (ç).
Nasal vowels
Portuguese has nasal vowel sounds with no direct English equivalent — air passes through the nose during the vowel, changing both its sound and meaning from the non-nasal version. Two are marked directly with a tilde in spelling: ã (as in mãe, "mother," or São) and õ (as in questões). Other nasal sounds are written with a vowel followed by m or n (bem, som) rather than a tilde. Getting these diacritics right matters for meaning, not just accent: irmã (sister) vs. irma is a real spelling distinction.
Grammatical gender
Nouns are masculine or feminine, with articles and adjectives agreeing: o menino alto (the tall boy), a menina alta (the tall girl). Gender generally follows the -o/-a pattern with exceptions to learn individually (o problema, a mão), similar to the pattern in Spanish and Italian.
European vs. Brazilian Portuguese
European and Brazilian Portuguese differ enough in spelling, vocabulary, and some grammar that specifying which variant is needed matters for any translation task — this isn't a minor accent difference. The Orthographic Agreement of 1990 unified some spelling differences between the two (and other Portuguese-speaking countries) but didn't eliminate them fully, and adoption has been uneven. Vocabulary differs notably: comboio vs. trem (train), autocarro vs. ônibus (bus), pequeno-almoço vs. café da manhã (breakfast). Grammar differs too — Brazilian Portuguese commonly places object pronouns before the verb where European Portuguese places them after or attaches them with a hyphen (te vejo vs. vejo-te), and Brazilian Portuguese uses gerund constructions (estou fazendo) more than European Portuguese, which favors the infinitive construction (estou a fazer).
Formal/informal address
Address conventions vary meaningfully by region rather than following one uniform pattern. In Brazil, você functions as a fairly neutral, widely used default for "you" in most everyday contexts, with tu used mainly in certain regions (notably the South and Northeast) — but você, despite looking like a formal pronoun historically, is not perceived as particularly formal in Brazilian usage. In Portugal, tu is the everyday informal form used with family, friends, and peers, while você reads as more formal or distant there than it does in Brazil, and formal address often uses o senhor/a senhora instead. This means the "same" pronoun carries a different formality register depending on which variant is in use.
Common pitfalls
- Translating into "Portuguese" without specifying European or Brazilian — vocabulary, some grammar, and even some spelling differ enough that the result can read as wrong or foreign to either audience.
- Dropping the tilde on nasal vowels (mae for mãe) — a real spelling error, not a cosmetic omission, and can create ambiguity.
- Assuming você carries the same formality in Portugal that it does in Brazil — it reads more formal/distant in Portugal than in Brazil.
- Using Brazilian object-pronoun placement or gerund constructions when European Portuguese is wanted, or vice versa.
- Guessing gender from the final vowel without checking exceptions like o problema, o dia, or a mão.
