From a classic, translated by this pipeline
The opening of Alice's Adventures in Wonderland by Lewis Carroll, translated English → Portuguese by the same pipeline that will translate your book. Nobody polished this by hand.
English original
Our Portuguese translation
Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, “and what is the use of a book,” thought Alice “without pictures or conversations?”
Alice estava a começar a ficar muito cansada de estar sentada ao lado da irmã na margem, e de não ter nada para fazer: uma ou duas vezes tinha espreitado para o livro que a irmã estava a ler, mas não tinha imagens nem diálogos, «e de que serve um livro», pensou Alice «sem imagens nem diálogos?»
What a faithful Portuguese edition must get right
Brazilian and European Portuguese differ in pronouns (você or tu), in where short pronouns sit in the sentence, and in vocabulary. The variant is chosen before translation starts and kept for the whole book.
Most Portuguese editions mark dialogue with the travessão (—). The punctuation system changes together with the text.
“You” has different forms by region and by level of formality. The form for each relationship is decided once, in the brief.
Before translation starts, we build a translator's brief from your whole book: names, terms, tone, typography. You read it and can change it. The brief then guides every chapter. Each passage is read again, independently, against your original, and translated again where that check finds a problem. The finished book gets one whole-book read for continuity. Every change goes into your quality report.
