One of the most significant differences between the two main dialects of Portuguese is vocabulary. Everyday words can vary significantly. For example, “breakfast” is pequeno-almoço in Portugal, and café da manhã in Brazil. Similarly, “train” is comboio in Portugal and trem in Brazil.
Over the centuries, Brazilian Portuguese has absorbed many words from indigenous and African languages. Interestingly, some of these words are now commonly used in Portugal because they refer to objects that did not exist in Europe before Brazil was colonized. Examples include jacaré (alligator) and abacaxi (pineapple).
Brazilian Portuguese has also adopted many English words, especially in IT and computing. For example, Brazilians will use the words laptop and mouse, whereas speakers in Portugal prefer computador portátil and rato.
Beyond IT, differences also appear in business and cultural contexts. For example, terms used in education, government, or even pop culture can vary, leading to confusion if the wrong variant is used. A translator must be attuned to these subtle shifts to produce text that feels natural to the target audience.
Portuguese translations need to use the right word to read smoothly. The reader may be able to understand unfamiliar words in context, but it will slow them down.
Additionally, some words have an innocent, everyday meaning in one dialect and a vulgar meaning in the other. Portuguese translators working in their native variant will know to avoid these words immediately.
